                      IMPORTANT NOTICE ABOUT INFORMATION IN
           THIS PROSPECTUS SUPPLEMENT AND THE ACCOMPANYING PROSPECTUS

         This document is in two parts. The first part is this prospectus
supplement, which describes the specific terms of the notes we are offering and
also adds to and updates certain information contained in the accompanying
prospectus and the documents incorporated by reference. The second part, the
accompanying prospectus dated March 26, 2004, gives more general information,
some of which may not apply to the notes we are offering. The accompanying
prospectus is referred to as the "prospectus" in this prospectus supplement.

         IF THE DESCRIPTION OF THE TERMS OF THE NOTES VARIES BETWEEN THIS
PROSPECTUS SUPPLEMENT AND THE PROSPECTUS, YOU SHOULD RELY ON THE INFORMATION IN
THIS PROSPECTUS SUPPLEMENT.

         YOU SHOULD RELY ONLY ON THE INFORMATION CONTAINED IN OR INCORPORATED BY
REFERENCE IN THIS PROSPECTUS SUPPLEMENT AND THE PROSPECTUS. WE HAVE NOT, AND THE
UNDERWRITERS HAVE NOT, AUTHORIZED ANY OTHER PERSON TO PROVIDE YOU WITH DIFFERENT
INFORMATION. IF ANYONE PROVIDES YOU WITH DIFFERENT OR INCONSISTENT INFORMATION,
YOU SHOULD NOT RELY ON IT. WE ARE NOT, AND THE UNDERWRITERS ARE NOT, MAKING AN
OFFER TO SELL THESE SECURITIES IN ANY JURISDICTION WHERE THE OFFER OR SALE IS
NOT PERMITTED. YOU SHOULD ASSUME THAT THE INFORMATION APPEARING IN THIS
PROSPECTUS SUPPLEMENT AND THE PROSPECTUS, AS WELL AS INFORMATION WE PREVIOUSLY
FILED WITH THE U.S. SECURITIES AND EXCHANGE COMMISSION AND WITH THE SECURITIES
REGULATORY AUTHORITY IN EACH OF THE PROVINCES AND TERRITORIES OF CANADA THAT IS
INCORPORATED BY REFERENCE, IS ACCURATE AS OF THEIR RESPECTIVE DATES ONLY. OUR
BUSINESS, FINANCIAL CONDITION, RESULTS OF OPERATIONS AND PROSPECTS AND THAT OF
ENCANA CORPORATION MAY HAVE CHANGED SINCE THOSE DATES.

         We are a wholly owned indirect subsidiary of EnCana Corporation. All
references in this prospectus supplement and the prospectus to "EnCana Holdings
Finance", "we", "us" and "our" mean EnCana Holdings Finance Corp. Unless the
context otherwise requires, references to "EnCana" and "the Guarantor" mean
EnCana Corporation and its consolidated subsidiaries or partnerships, except
that in the sections entitled "Summary of the Offering" and "Description of the
Notes" in this prospectus supplement and "Description of Debt Securities" in the
prospectus, references to "EnCana Corporation" and "the Guarantor" mean EnCana
Corporation, without any of its subsidiaries or partnerships through which it
operates.

         In this prospectus supplement, all capitalized terms used and not
otherwise defined herein have the meanings provided in the prospectus. In this
prospectus supplement, the prospectus and any document incorporated by
reference, unless otherwise specified or the context otherwise requires, all
dollar amounts are expressed in United States dollars, and all financial
information is determined using generally accepted accounting principles which
are in effect from time to time in Canada ("Canadian GAAP"). "U.S. GAAP" means
generally accepted accounting principles which are in effect from time to time
in the United States. For a discussion of the principal differences between
EnCana's financial results as calculated under Canadian GAAP and under U.S.
GAAP, you should refer to note 20 of EnCana's audited comparative consolidated
financial statements for the year ended December 31, 2003, incorporated by
reference in the prospectus.

         This prospectus supplement contains disclosure respecting oil and gas
production expressed as "cubic feet of natural gas equivalent" and "barrels of
oil equivalent" or "boe". All equivalency volumes have been derived using the
ratio of six thousand cubic feet of natural gas to one barrel of oil.
Equivalency measures may be misleading, particularly if used in isolation. A
conversion ratio of six thousand cubic feet of natural gas to one barrel of oil
is based on an energy equivalence conversion method primarily applicable at the
burner tip and does not represent a value equivalency at the wellhead.

                           FORWARD-LOOKING STATEMENTS

         Certain statements included in this prospectus supplement, the
prospectus and the documents incorporated by reference therein constitute
forward-looking statements within the meaning of the United States Private
Securities Litigation Reform Act of 1995 relating to, but not limited to, the
operations of EnCana (including the U.S. Group, as hereinafter defined),
anticipated financial performance, business prospects and strategies.
Forward-looking statements typically contain statements with words such as
"anticipate", "believe", "expect", "plan", "intend" or similar words suggesting
future outcomes or statements regarding an outlook on crude oil and natural gas
prices, estimates of future production, reserves and resources, the estimated
amounts and timing of capital expenditures, anticipated future debt levels and
royalty rates, or other expenditures, beliefs, plans, objectives, assumptions or
statements about future events or performance.

         You are cautioned not to place undue reliance on forward-looking
statements. By their nature, forward-looking statements involve numerous
assumptions, inherent risks and uncertainties, both general and specific, that
contribute to the possibility that the predicted outcomes will not occur. These
factors include, but are not limited to:

         o        general economic, business and market conditions;

         o        volatility of crude oil, natural gas and natural gas liquids
                  prices;

         o        fluctuations in currency and interest rates, product supply
                  and demand;

         o        competition;

         o        risks inherent in foreign operations, including political and
                  economic risk;

         o        risks of war, hostilities, civil insurrection and terrorist
                  threats;

         o        risks inherent in marketing operations including credit risks;

         o        imprecision of reserve estimates;

         o        EnCana's ability to replace or expand reserves;

         o        EnCana's ability to either generate sufficient cash flow to
                  meet current and future obligations or to obtain external debt
                  or equity financing;

         o        EnCana's ability to enter into or renew leases;

         o        the timing and costs of pipeline and natural gas storage
                  facility construction and expansion;

         o        EnCana's ability to make capital investments and the amounts
                  thereof;

         o        imprecision in estimating future production capacity, and the
                  timing, costs and levels of production and drilling;

         o        results of EnCana's exploration, development and drilling
                  activity;

         o        EnCana's ability to secure adequate product transportation;

         o        changes in regulations, including environmental regulations;

         o        risks associated with existing and potential future lawsuits
                  and regulatory actions against EnCana;

         o        uncertainty in amounts and timing of royalty payments; and

         o        imprecision in estimating product sales.

         We caution that the foregoing list of important factors is not
exhaustive. Events or circumstances could cause our or EnCana's actual results
to differ materially from those estimated or projected and expressed in, or
implied by, these forward-looking statements. You should also carefully consider
the matters discussed under "Risk Factors" in the prospectus. Neither we nor
EnCana Corporation undertake any obligation to update publicly or otherwise
revise any forward-looking statements, whether as a result of new information,
future events or otherwise, or the foregoing list of factors affecting this
information.

                                   See "Description of Debt
                                   Securities--Covenants" in the prospectus.
                                   These covenants are subject to important
                                   exceptions and qualifications which are
                                   described under the caption "Description of
                                   Debt Securities" in the prospectus.

USE OF PROCEEDS................    The net proceeds to us from this offering
                                   will be approximately US$988.6 million, after
                                   deducting the underwriting commission and the
                                   estimated expenses payable by us of
                                   approximately US$1.0 million. The net
                                   proceeds received by us from the sale of the
                                   notes will be loaned to the parent
                                   partnership of the U.S. Group to be used to
                                   pay a portion of the acquisition cost for the
                                   proposed acquisition of Tom Brown, Inc. ("Tom
                                   Brown"). If the acquisition of Tom Brown is
                                   not completed, the net proceeds loaned to the

                                   used to repay indebtedness of the U.S. Group
                                   or for other general corporate purposes of

ADDITIONAL AMOUNTS.............    Any payments made by us with respect to the
                                   notes will be made without withholding or
                                   deduction for Canadian taxes unless required
                                   to be withheld or deducted by law or by the
                                   interpretation or administration thereof. If
                                   we are so required to withhold or deduct for
                                   Canadian taxes with respect to a payment to
                                   the holders of notes, we will pay the
                                   additional amount necessary so that the net
                                   amount received by the holders of notes after
                                   such withholding or deduction is not less
                                   than the amount that such holders would have
                                   received in the absence of the withholding or
                                   deduction. However, no additional amount will
                                   be payable in excess of the additional amount
                                   that would be payable if the holder was a
                                   resident of the United States for purposes of

                          ENCANA HOLDINGS FINANCE CORP.

         We are an unlimited liability company incorporated on August 25, 2003
under the laws of the province of Nova Scotia, Canada. We are a wholly owned
indirect subsidiary of EnCana Corporation and are part of a group of EnCana
Corporation's subsidiaries and partnerships which carry on substantially all of
EnCana Corporation's operations in the United States (the "U.S. Group"). We have
been established for the purpose of raising financing for the U.S. Group. We
have no subsidiaries and, except as aforesaid, have no active business.

         The U.S. Group is involved in both upstream and midstream operations.
The upstream operations of the U.S. Group are currently focused on exploiting
deep, tight, long life natural gas formations primarily in the Jonah sweet
natural gas field located in the Green River Basin of southwest Wyoming and the
Mamm Creek natural gas field located in the Piceance Basin of northwest
Colorado. The U.S. Group also explores for, develops and produces natural gas
and crude oil in other areas, including north Texas, the Gulf of Mexico and
Alaska. The U.S. Group's midstream operations include an extensive natural gas
storage network with facilities in California and Oklahoma, as well as various
natural gas gathering and processing assets.

         The funds required by us to satisfy our obligations under the notes we
issue under this prospectus supplement will be obtained through our debt
interests in other members of the U.S. Group or through other advances from
EnCana Corporation or its subsidiaries or partnerships. The notes will be fully
and unconditionally guaranteed by EnCana Corporation.

                               ENCANA CORPORATION

         EnCana Corporation is one of the world's leading independent crude oil
and natural gas exploration and production companies, based on landholdings and
production at December 31, 2003. EnCana's key landholdings are in Western
Canada, the U.S. Rocky Mountains, Ecuador, the United Kingdom ("U.K.") central
North Sea, offshore Canada's East Coast and the Gulf of Mexico. It explores for,
produces and markets natural gas, crude oil and natural gas liquids ("NGLs") in
Canada and the United States. EnCana is also engaged in exploration and
production activities internationally including production from Ecuador and the
U.K. central North Sea. EnCana has interests in midstream operations and assets,
including natural gas storage, NGLs gathering and processing facilities, power
plants and pipelines.

                               RECENT DEVELOPMENTS

PROPOSED ACQUISITION OF TOM BROWN, INC.

         EnCana has entered into an agreement and plan of merger, dated as of
April 14, 2004, with independent energy company Tom Brown of Denver, Colorado
providing for the acquisition by a wholly owned subsidiary of EnCana of all of
the outstanding shares of Tom Brown, for cash, at a price of US$48.00 per share.
The shares of Tom Brown are listed on the New York Stock Exchange. EnCana
estimates that the total consideration for the acquisition will be approximately
US$2.7 billion, including acquired debt of Tom Brown (which, at December 31,
2003, was approximately US$400 million). EnCana has arranged a US$3 billion
non-revolving bridge financing with a Canadian chartered bank to fund the
acquisition.

         Pursuant to the agreement between EnCana and Tom Brown, a subsidiary of
EnCana has commenced a tender offer to purchase all of the outstanding shares of
Tom Brown. The Tom Brown board of directors has recommended to the shareholders
of Tom Brown that they accept the offer and the directors and senior executive
team of Tom Brown have informed EnCana of their intention to tender their shares
to the offer. The tender offer is scheduled to expire on May 18, 2004. If the
tender offer is successful, following its completion and receipt of any
necessary Tom Brown stockholder approval, Tom Brown will merge with a subsidiary
of EnCana and each share of Tom Brown not tendered in the tender offer will be
converted into the right to receive US$48.00 in cash. Upon completion of the
merger, Tom Brown will become an indirect wholly owned subsidiary of EnCana and
part of the U.S. Group.

         The completion of the tender offer and merger of the EnCana subsidiary
and Tom Brown is subject to the tender of at least a majority of Tom Brown's
outstanding shares on a fully diluted basis and other customary conditions.

         Tom Brown is engaged primarily in the exploration for, and the
acquisition, development, production, marketing, and sale of, natural gas, NGLs
and crude oil in North America. Its activities are conducted principally in the
Wind River and Green River Basins of Wyoming, the Piceance Basin of Colorado,
the Paradox Basin of Utah and Colorado, the Val Verde Basin and Permian Basin of
west Texas and southeast New Mexico, the East Texas Basin and the Western
Canadian Sedimentary Basin.


                                       S-7


         EnCana expects, based on its preliminary assessment of information
provided to EnCana by Tom Brown, that the acquisition of Tom Brown would add
current production of approximately 325 million cubic feet of natural gas
equivalent per day (of which approximately 87% is natural gas production),
approximately 1.2 trillion cubic feet of proved natural gas equivalent reserves
(of which approximately 92% is natural gas reserves) and approximately 2 million
net undeveloped acres.

PLANNED DISPOSITIONS

         EnCana has announced that it plans to sell, over the next 12 months,
conventional assets currently producing between 40,000 and 60,000 barrels of oil
equivalent per day for estimated proceeds of US$1 billion to US$1.5 billion.

                                 USE OF PROCEEDS

         The net proceeds to us from this offering will be approximately
US$988.6 million, after deducting the underwriting commission and the estimated
expenses payable by us of approximately US$1.0 million. The net proceeds
received by us from the sale of the notes will be loaned to the parent
partnership of the U.S. Group to be used to pay a portion of the acquisition
cost for the proposed acquisition of Tom Brown. If the acquisition of Tom Brown
is not completed, the net proceeds loaned to the parent partnership of the U.S.
Group will be used to repay indebtedness of the U.S. Group or for other general
corporate purposes of the U.S. Group.

(1)      Cash flow is not a measure that has any standardized meaning prescribed
         by Canadian GAAP and is considered a non-GAAP measure. Therefore, this
         measure may not be comparable to similar measures presented by other
         issuers. Cash flow is presented in order to provide additional
         information regarding the Guarantor's liquidity and its ability to
         generate funds to finance its operations. Cash flow is not intended to
         represent the Guarantor's operating cash flows or operating profits for
         the period nor should it be viewed as an alternative to cash flow from
         operating activities, net earnings or other measures of financial
         performance calculated in accordance with Canadian GAAP.

         exchange (gain) loss, Accretion of asset retirement obligation,
         Interest, net and Depreciation, depletion and amortization. EBITDA is
         not a measure that has any standardized meaning prescribed by Canadian
         GAAP and is considered a non-GAAP measure. Therefore, this measure may
         not be comparable to similar measures presented by other issuers.
         EBITDA is presented in order to provide additional information
         regarding the Guarantor's liquidity and its ability to generate funds
         to finance its operations. EBITDA should not be considered an
         alternative to net earnings, cash flow from operating activities or
         other measures of financial performance calculated in accordance with
         Canadian GAAP.

(1)      As described under "Use of Proceeds", the net proceeds received by us
         from the sale of the notes will be loaned to the parent partnership of
         the U.S. Group to be used to pay a portion of the acquisition cost for
         the proposed acquisition of Tom Brown. If the acquisition of Tom Brown
         is not completed, the net proceeds loaned to the parent partnership of
         the U.S. Group will be used to repay indebtedness of the U.S. Group or
         for other general corporate purposes of the U.S. Group. If indebtedness
         of the U.S. Group is repaid with the net proceeds received by us from
         the sale of the notes, the indebtedness repaid will be indebtedness
         payable to certain subsidiaries of EnCana which are not members of the
         U.S. Group. The funds received from such repayment will be used to
         repay revolving credit and term loan borrowings of EnCana.

(2)      Excludes current portion of long-term debt.

(3)      The Guarantor and its subsidiaries have two revolving credit and term
         loan facilities in place totalling approximately C$4.4 billion (US$3.4
         billion) at March 31, 2004. One of the facilities, totalling C$4
         billion (US$3.1 billion), consists of two tranches of C$2 billion
         (US$1.5 billion) each. One tranche is fully revolving for a 364-day
         period with provision for annual extensions at the option of the
         lenders and upon notice from the Guarantor. If not extended, this
         tranche converts to a non-revolving reducing loan for a term of one
         year. The second tranche is fully revolving for a period of three years
         from December 2003 with provision for annual extensions at the option
         of the lenders and upon notice from the Guarantor. The other facility,
         for one of the Guarantor's subsidiaries, totalling $300 million (C$393
         million), is guaranteed by the Guarantor and fully revolving for three
         years from December 2003. The facility is extendable annually for an
         additional one year period at the option of the lenders and upon notice
         from the subsidiary. Revolving credit and term loan borrowings include
         bankers acceptance, LIBOR loan and commercial paper indebtedness of
         $1,780 million as at March 31, 2004.

(4)      Canadian dollar denominated debt has been converted to U.S. dollar
         amounts using the exchange rate of C$1.00 equals US$0.7631 at March 31,
         2004.

(5)      Subsequent to March 31, 2004, the Guarantor arranged a $3 billion
         non-revolving term loan facility to fund the proposed Tom Brown
         acquisition and other related costs. Amounts borrowed under the
         facility are to be repaid as follows: 25 percent within 9


                                       S-11


         months of the initial drawdown, a further 50 percent within 15 months
         of the initial drawdown, and the final 25 percent within 24 months of
         the initial drawdown.

(6)      In addition to the notes offered hereby, we may incur additional
         long-term indebtedness, under our new $3 billion credit facility or
         otherwise, to fund the approximately $2.7 billion proposed acquisition
         of Tom Brown.

(7)      An unlimited number of common shares are authorized. At March 31, 2004,
         there were approximately 459.8 million common shares outstanding.

(8)      The Guarantor has option plans which permit common shares to be
         reserved for issuance pursuant to options granted to its directors and
         employees. At March 31, 2004, options to purchase approximately 24.2
         million common shares were outstanding, 11.3 million of which were then
         exercisable, at exercise prices ranging from C$13.50 to C$53.00 per
         common share.

(9)      Share options, net is defined as the fair value of AEC share options
         exchanged for share options of the Guarantor as part of the Merger.

                                 CREDIT RATINGS

         The notes have been assigned a rating of "A--" by Standard & Poor's
Ratings Services ("S&P"), a rating of "Baal" by Moody's Investors Service
("Moody's") and a rating of "A (low)" by Dominion Bond Rating Service Limited
("DBRS"). Credit ratings are intended to provide investors with an independent
measure of credit quality of any issue of securities. The rating by S&P is on
CreditWatch with negative implications, the rating by Moody's is under review
for downgrade and the rating by DBRS is with a negative trend.

         S&P's credit ratings are on a long-term debt rating scale that ranges
from AAA to D, which represents the range from highest to lowest quality of such
securities rated. A rating of A-- by S&P is the third highest of eleven
categories and indicates that the obligor is somewhat more susceptible to the
adverse effects of changes in circumstances and economic conditions than
obligors in higher-rated categories. However, the obligor's capacity to meet its
financial commitment on the obligation is still strong. The addition of a plus
(+) or minus (--) designation after a rating indicates the relative standing
within a particular rating category.

         Moody's credit ratings are on a long-term debt rating scale that ranges
from Aaa to C, which represents the range from highest to lowest quality of such
securities rated. A rating of Baal by Moody's is the fourth highest of nine
categories and is assigned to debt securities which are considered medium-grade
obligations (i.e. they are neither highly protected nor poorly secured).
Interest payments and principal security appear adequate for the present but
certain protective elements may be lacking or may be characteristically
unreliable over any great length of time. Such debt securities lack outstanding
investment characteristics and in fact have speculative characteristics as well.
The addition of a 1, 2 or 3 modifier after a rating indicates the relative
standing within a particular rating category. The modifier 1 indicates that the
issue ranks in the higher end of its generic rating category, the modifier 2
indicates a mid-range ranking and the modifier 3 indicates that the issue ranks
in the lower end of its generic rating category.

         DBRS' credit ratings are on a long-term debt rating scale that ranges
from AAA to D, which represents the range from highest to lowest quality of such
securities rated. A rating of A (low) by DBRS is the third highest of nine
categories and is assigned to debt securities considered to be of satisfactory
credit quality. Protection of interest and principal is still substantial, but
the degree of strength is less than with AA rated entities. While a respectable
rating, entities in the A category are considered to be more susceptible to
adverse economic conditions and have greater cyclical tendencies than higher
rated companies. The assignment of a "(high)" or "(low)" modifier within each
rating category indicates relative standing within such category. The "high" and
"low" grades are not used for the AAA category.

         The credit ratings accorded to the notes by the rating agencies are not
recommendations to purchase, hold or sell the notes inasmuch as such ratings do
not comment as to market price or suitability for a particular investor. Any
rating may not remain in effect for any given period of time or may be revised
or withdrawn entirely by a rating agency in the future if in its judgement
circumstances so warrant, and if any such rating is so revised or withdrawn, we
are under no obligation to update this prospectus supplement.

                            DESCRIPTION OF THE NOTES

         The following description of the terms of the notes (referred to in the
prospectus as the "debt securities") supplements, and to the extent inconsistent
therewith replaces, the description set forth under "Description of Debt
Securities" in the prospectus and should be read in conjunction with such
description. Capitalized terms used but not defined in this prospectus
supplement have the meanings ascribed to them in the prospectus. In this
section, "EnCana Corporation" or "the Guarantor" refer to EnCana Corporation
without any of its subsidiaries or partnerships through which it operates.

GENERAL

         Payment of the principal, premium, if any, and interest on the notes
will be made in United States dollars.

         The notes initially will be issued in an aggregate principal amount of
US$1.0 billion and will mature on May 1, 2014. The notes will bear interest at
the rate of 5.80% per year from May 13, 2004 or from the most recent date to
which interest has been paid or provided for, payable semi-annually on May 1 and
November 1 of each year, commencing November 1, 2004 to the persons in whose
names the notes are registered at the close of business on the preceding April
15 or October 15, respectively. The notes will be sold in denominations of
US$1,000 and integral multiples thereof.

         We may from time to time without notice to, or the consent of, the
holders of the notes, create and issue additional notes under the Indenture.
Unless otherwise set forth in a prospectus supplement, such additional notes
will rank equally and have the same terms as the notes offered hereby in all
respects (or in all respects except for the payment of interest accruing prior
to the issue date of the new notes, or except for the first payments of interest
following the issue date of the new notes) so that the new notes may be
consolidated and form a single series with these notes. In the event that
additional notes are issued, we will prepare a new prospectus supplement.

         The notes will not be entitled to the benefits of any sinking fund. We
may issue debt securities and incur additional indebtedness other than through
the offering of notes pursuant to this prospectus supplement.

         The provisions of the Indenture relating to the payment of Additional
Amounts in respect of Canadian withholding taxes in certain circumstances
(described under the caption "Description of Debt Securities--Additional
Amounts" in the prospectus) and the provisions of the Indenture relating to the
redemption of notes in the event of specified changes in Canadian withholding
tax law on or after the date of this prospectus supplement (described under the
caption "Description of Debt Securities--Tax Redemption" in the prospectus) will
apply to the notes.

GUARANTEE

         The notes will be fully and unconditionally guaranteed by EnCana
Corporation as to payment of principal (and premium, if any) and interest, if
any, and any Additional Amounts.

RANKING AND OTHER INDEBTEDNESS

         The notes will be our direct, unsecured and unsubordinated obligations
and will rank equally with all of our unsecured and unsubordinated debt. The
notes and the guarantee will be effectively subordinated to all of our and the
Guarantor's secured debt to the extent of the assets securing such debt.

         The guarantee will be the Guarantor's unsecured and unsubordinated
obligation, ranking equally in right of payment with all of its other unsecured,
unsubordinated obligations outstanding from time to time. The Guarantor conducts
a substantial portion of its business through corporate and partnership
subsidiaries. The Guarantor's obligations under the guarantee will be
structurally subordinate to all existing and future indebtedness and liabilities
of any of the Guarantor's corporate and partnership subsidiaries. As at March
31, 2004, the Guarantor's corporate and partnership subsidiaries had no
long-term debt outstanding to third parties.

OPTIONAL REDEMPTION

         The notes will be redeemable, in whole or in part, at our option at any
time at a redemption price equal to the greater of:

         o        100% of the principal amount of the notes to be redeemed, and


                                       S-15


         o        the sum of the present values of the remaining scheduled
                  payments of principal and interest on the notes to be redeemed
                  (exclusive of interest accrued to the date of redemption)
                  discounted to the redemption date on a semi-annual basis
                  (assuming a 360-day year consisting of twelve 30-day months)
                  at the Adjusted Treasury Rate (as defined below) plus 20 basis
                  points,

in either case, plus accrued interest thereon to the date of redemption.

         "ADJUSTED TREASURY RATE" means, with respect to any redemption date,
the rate per year equal to the semi-annual equivalent yield to maturity of the
Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue
(expressed as a percentage of its principal amount) equal to the Comparable
Treasury Price for such redemption date.

         "COMPARABLE TREASURY ISSUE" means the United States Treasury security
or securities selected by the Independent Investment Banker as having an actual
or interpolated maturity comparable to the remaining term of the notes to be
redeemed that would be utilized, at the time of selection and in accordance with
customary financial practice, in pricing new issues of corporate debt securities
of comparable maturity to the remaining term of the notes.

         "COMPARABLE TREASURY PRICE" means, with respect to any redemption date,
(A) the average of the Reference Treasury Dealer Quotations for such redemption
date, after excluding the highest and lowest such Reference Treasury Dealer
Quotations, or (B) if fewer than four such Reference Treasury Dealer Quotations
are obtained, the average of all such quotations.

         "INDEPENDENT INVESTMENT BANKER" means one of the Reference Treasury
Dealers, which is appointed by the Trustee after consultation with us.

         "REFERENCE TREASURY DEALERS" means each of Deutsche Bank Securities
Inc. and Morgan Stanley & Co. Incorporated or their affiliates, plus three
others which are primary U.S. Government securities dealers and their respective
successors; PROVIDED, HOWEVER, that if any of the foregoing or their affiliates
shall cease to be a primary U.S. Government securities dealer in the United
States (a "Primary Treasury Dealer"), we shall substitute for it another Primary
Treasury Dealer.

         "REFERENCE TREASURY DEALER QUOTATIONS" means, with respect to each
Reference Treasury Dealer and any redemption date, the average, as determined by
the Reference Treasury Dealer, of the bid and asked prices for the Comparable
Treasury Issue (expressed in each case as a percentage of its principal amount)
quoted by such Reference Treasury Dealers at 3:30 p.m. New York Time on the
third business day preceding such redemption date.

         Notice of any redemption will be mailed at least 30 days but not more
than 60 days before the redemption date to each holder of the notes to be
redeemed.

         Unless we default in payment of the redemption price, on and after the
redemption date, interest will cease to accrue on the notes or the portions of
the notes called for redemption.

         In the case of a partial redemption of notes, selection of such notes
for redemption will be made PRO RATA, by lot or such other method as the Trustee
in its sole discretion deems appropriate and just. If any note is redeemed in
part, the notice of redemption relating to such note shall state the portion of
the principal amount thereof to be redeemed; PROVIDED that no note in an
aggregate principal amount of US$1,000 or less shall be redeemed in part. A
replacement note in principal amount equal to the unredeemed portion thereof
will be issued in the name of the holder thereof upon cancellation of the
original note.

BOOK-ENTRY SYSTEM

         The Depository Trust Company (hereinafter referred to as the
"Depositary") will act as securities depository for the notes. The notes will be
issued as fully registered notes registered in the name of Cede & Co. (the
Depositary's nominee). One or more fully registered global notes (hereinafter
referred to as the "global notes") will be issued for each of the notes, in the
aggregate principal amount of the issue, and will be deposited with the
Depositary. The provisions set forth under "Description of Debt
Securities--Global Securities" in the prospectus will be applicable to the
notes.

         The following is based on information furnished by the Depositary:

         The Depositary is a limited-purpose trust company organized under the
New York Banking Law, a "banking organization" within


                                       S-16


the meaning of the New York Banking Law, a member of the Federal Reserve System,
a "clearing corporation" within the meaning of the New York Uniform Commercial
Code, and a "clearing agency" registered pursuant to the provisions of Section
17A of the United States Securities Exchange Act of 1934. The Depositary also
facilitates the settlement among participants of notes transactions, such as
transfers and pledges, in deposited notes through electronic computerized
book-entry charges in participants' accounts, thereby eliminating the need for
physical movement of notes certificates. Direct participants include:

         o        securities brokers and dealers;

         o        banks;

         o        trust companies;

         o        depositories for Euroclear and Clearstream;

         o        clearing corporations; and

         o        certain other organizations.

         The Depositary is owned by a number of its direct participants and by
the New York Stock Exchange, Inc., the American Stock Exchange, LLC, and the
National Association of Securities Dealers, Inc. Access to the Depositary's
system is also available to others such as securities brokers and dealers, banks
and trust companies that clear through or maintain a custodial relationship with
a direct participant, either directly or indirectly, in the case of "indirect
participants". The rules applicable to the Depositary and its participants are
on file with the SEC.

         Purchases of notes under the Depositary's system must be made by or
through direct participants, which will receive a credit for the notes on the
Depositary's records. The ownership interest of each actual purchaser of notes
represented by the global notes by a "beneficial owner" is in turn to be
recorded on the direct and indirect participant's records. Beneficial owners
will not receive written confirmation from the Depositary of their purchases but
beneficial owners are expected to receive written confirmation providing details
of the transaction, as well as periodic statements of their holdings, from the
direct or indirect participants through which the beneficial owners entered into
the transaction. Transfers of ownership interest in the global notes
representing the notes are to be accomplished by entries made on the books of
participants acting on behalf of beneficial owners. Beneficial owners of the
global notes representing notes will not receive notes in definitive form
representing their ownership interests, except in the event that use of the
book-entry system for the notes is discontinued or upon the occurrence of
certain other events described in this prospectus supplement.

         To facilitate subsequent transfers, the global notes representing notes
which are deposited with the Depositary are registered in the name of the
Depositary's nominee, Cede & Co. The deposit of the global notes with the
Depositary and its registration in the name of Cede & Co. effect no change in
beneficial ownership. The Depositary has no knowledge of the actual beneficial
owners of the global notes representing the notes. The Depositary's records
reflect only the identity of the direct participants to whose accounts the notes
are credited, which may or may not be the beneficial owners. The participants
will remain responsible for keeping account of their holdings on behalf of their
customers.

         Conveyance of notices and other communications by the Depositary to
direct participants, by direct participants to indirect participants and by
direct participants and indirect participants to beneficial owners will be
governed by arrangements among them, subject to any statutory or regulatory
requirements as may be in effect from time to time.

         Neither the Depositary nor Cede & Co. will consent or vote with respect
to the global notes representing the notes. Under its usual procedures, the
Depositary mails an "omnibus proxy" to us as soon as possible after the
applicable record date. The omnibus proxy assigns Cede & Co.'s consenting or
voting rights to those direct participants whose accounts the notes are credited
on the applicable record date (identified in a listing attached to the omnibus
proxy).

         Principal and interest payments on the global notes representing the
notes will be made to the Depositary. The Depositary's practice is to credit
direct participants' accounts on the applicable payment date in accordance with
their respective holdings shown on the Depositary's records unless the
Depositary has reason to believe that it will not receive payment on that date.
Payments by participants to beneficial owners will be governed by standing
instructions and customary practices, as is the case with notes held for the
account of customers in bearer form or registered in "street name", and will be
the responsibility of the participant and not of the Depositary, the Trustee or
us, subject to any statutory or regulatory requirements as may be in effect from
time to time. Payment of


                                       S-17


principal and interest to the Depositary is the responsibility of us or the
Trustee, disbursement of these payments to direct participants shall be the
responsibility of the Depositary, and disbursement of these payments to the
beneficial owners shall be the responsibility of direct and indirect
participants. Neither we nor the Trustee will have any responsibility or
liability for disbursements of payments in respect of ownership interest in the
notes by the Depositary or the direct or indirect participants or for
maintaining or reviewing any records of the Depositary or the direct or indirect
participants relating to ownership interests in the notes or the disbursement of
payments in respect of the notes.

         The information in this section concerning the Depositary and the
Depositary's system has been obtained from sources that we believe to be
reliable, but is subject to any changes to the arrangements between us and the
Depositary and any changes to these procedures that may be instituted
unilaterally by the Depositary.

CERTIFICATED NOTES

         The Depositary may discontinue providing its services as depository
with respect to the notes at any time by giving reasonable notice to us and the
Trustee. Under these circumstances, and in the event that a successor depository
is not appointed, notes in certificated form are required to be printed and
delivered. We may decide to discontinue use of the system of book-entry
transfers through the Depositary (or a successor depository). In that event,
notes in certificated form will be printed and delivered. If at any time the
Depositary ceases to be a clearing agency registered under the Exchange Act and
a successor depository is not appointed by us within 90 days or if there shall
have occurred and be continuing an Event of Default under the Indenture with
respect to the notes and the Trustee has received a request from a beneficial
holder of outstanding notes to issue notes in certificated form to such holder,
we will issue individual notes in certificated form in exchange for the global
notes.

                         CERTAIN INCOME TAX CONSEQUENCES

         THE FOLLOWING SUMMARY IS OF A GENERAL NATURE ONLY AND IS NOT INTENDED
TO BE, AND SHOULD NOT BE CONSTRUED TO BE, LEGAL OR TAX ADVICE TO ANY PROSPECTIVE
INVESTOR AND NO REPRESENTATION WITH RESPECT TO THE TAX CONSEQUENCES TO ANY
PARTICULAR INVESTOR IS MADE. ACCORDINGLY, PROSPECTIVE INVESTORS SHOULD CONSULT
WITH THEIR OWN TAX ADVISORS FOR ADVICE WITH RESPECT TO THE INCOME TAX
CONSEQUENCES TO THEM OF PURCHASING, HOLDING OR DISPOSING OF THE NOTES HAVING
REGARD TO THEIR OWN PARTICULAR CIRCUMSTANCES, INCLUDING ANY CONSEQUENCES OF AN
INVESTMENT IN THE NOTES ARISING UNDER STATE, PROVINCIAL OR LOCAL TAX LAWS IN THE
UNITED STATES OR CANADA OR TAX LAWS OF JURISDICTIONS OUTSIDE THE UNITED STATES
OR CANADA.

CERTAIN CANADIAN FEDERAL INCOME TAX CONSIDERATIONS

         The following summary describes the principal Canadian federal income
tax considerations generally applicable to you as a consequence of acquiring,
holding and disposing of notes; provided that you, at all relevant times, for
the purposes of the INCOME TAX ACT (Canada) (the "Tax Act") deal with us and the
Guarantor at arm's length, are not, and are not deemed to be, a resident of
Canada, do not use or hold and are not deemed by the provisions of the Tax Act
to use or hold the notes in the course of carrying on a business in Canada and,
where you carry on an insurance business in Canada and elsewhere, you establish
that the notes are neither "designated insurance property" (as defined in the
Tax Act and the regulations thereunder (the "Regulations")) nor effectively
connected with the insurance business you carry on in Canada.

         This summary is based upon the current provisions of the Tax Act and
the Regulations, all specific proposals to amend such provisions publicly
announced by or on behalf of the Minister of Finance (Canada) prior to the date
hereof, and an understanding of the current published administrative practices
of the Canada Revenue Agency. This summary is not exhaustive of all possible
Canadian federal income tax consequences, and except as noted above does not
take into account or anticipate any changes in law, whether by legislative,
governmental or judicial action, and does not take into account tax legislation
or considerations of any province, territory or foreign jurisdiction, which may
differ from the federal income tax considerations.

         Under the Tax Act, you will not be subject to Canadian withholding tax
in respect of any amounts paid or credited by us to you as, on account of, in
lieu of, or in satisfaction of interest on the notes. There are no other
Canadian taxes on income or capital gains payable under the Tax Act in respect
of the holding, redemption or disposition of the notes or the receipt of
interest on the notes by you from us, or the Guarantor, as the case may be.

CERTAIN U.S. FEDERAL INCOME TAX CONSIDERATIONS

         The following summary describes certain U.S. federal income tax
consequences that may be relevant to the purchase, ownership and disposition of
notes by U.S. Holders and Non-U.S. Holders (as defined below). This summary does
not address tax consequences applicable to subsequent purchasers of the notes.
This discussion does not purport to deal with all aspects of U.S. federal income
taxation that may be relevant to particular holders in light of their particular
circumstances nor does it deal with persons that are subject to special tax
rules, such as dealers in securities or currencies, financial institutions,
insurance companies, tax-exempt organizations, persons holding the notes as a
part of a straddle, hedge, or conversion transaction or a synthetic security or
other integrated transaction, U.S. expatriates, persons whose "functional
currency" is not the U.S. dollar. This discussion does not cover any state,
local, or foreign tax consequences. The discussion is based upon the provisions
of the Code and United States Treasury regulations, rulings and judicial
decisions under the Code, all as currently in effect as of the date of this
prospectus supplement, and those authorities may be repealed, revoked or
modified (possibly with retroactive effect) so as to result in U.S. federal
income tax consequences different from those discussed below. There can be no
assurance that the Internal Revenue Service (the "IRS") will take a similar view
as to any of the tax consequences described in this summary.

         PERSONS CONSIDERING THE PURCHASE, OWNERSHIP OR DISPOSITION OF NOTES
SHOULD CONSULT THEIR OWN TAX ADVISORS CONCERNING THE U.S. FEDERAL INCOME TAX
CONSEQUENCES IN LIGHT OF THEIR PARTICULAR SITUATIONS AS WELL AS ANY CONSEQUENCES
ARISING UNDER THE LAWS OF ANY STATE OR OF ANY LOCAL OR FOREIGN TAXING
JURISDICTION.

U.S. HOLDERS

         As used in this section, the term "U.S. Holder" means a beneficial
owner of a note that purchases notes in this offering and that holds the notes
as capital assets within the meaning of Section 1221 of the Internal Revenue
Code of 1986 (the "Code"), and that is (i)


                                       S-19


a citizen or resident of the United States, (ii) a corporation created or
organized in or under the laws of the United States or any political subdivision
thereof or therein, (iii) an estate the income of which is subject to U.S.
federal income taxation regardless of its source, or (iv) a trust (A) which is
subject to the supervision of a court within the United States and the control
of a United States person, or (B) that was in existence on August 20, 1996, was
treated as a United States person under the Code on the previous day, and
validly elected to continue to be so treated under applicable United States
Treasury regulations.

         As used herein, "Non-U.S. Holder" means a beneficial owner of a note
that purchases notes in this offering, holds the notes as capital assets within
the meaning of Section 1221 of the Code, and is not a U.S. Holder.

         If a partnership holds a note, the U.S. federal income tax treatment of
a partner generally will depend on the status of the partner and the activities
of the partnership. A U.S. holder that is a partner of the partnership holding a
note should consult its own tax advisors.

CHARACTERIZATION OF ENCANA HOLDINGS FINANCE CORP. AND THE NOTES

         We believe that EnCana Holdings Finance will be treated as a
"disregarded entity" for U.S. federal income tax purposes, and accordingly, that
its assets and liabilities should be treated as assets and liabilities of its
100% shareholder, the parent of the U.S. Group. Accordingly, the notes should be
treated as issued by the parent of the U.S. Group for U.S. federal income tax
purposes.

PAYMENTS OF INTEREST

         Interest on a note will generally be includable by a U.S. Holder as
ordinary income at the time the interest is paid or accrued, depending on the
U.S. Holder's method of accounting for U.S. federal income tax purposes. In
addition to interest on the notes, a U.S. Holder would be required to include as
income any Canadian withholding taxes and any additional amounts we may pay as a
result of the imposition of Canadian withholding taxes. As a result, a U.S.
Holder may be required to include more amounts in gross income than the amount
of cash it actually receives. A U.S. Holder may be entitled to deduct or credit
foreign withheld tax, subject to applicable limitations in the Code. We believe
that for U.S. foreign tax credit purposes and other U.S. tax purposes, interest
income on the notes should constitute income from sources within the United
States. U.S. foreign tax credits generally are not available to reduce taxes
imposed on income from sources within the United States, such as interest on the
notes. Accordingly, a U.S. Holder will not be able to claim a credit for
Canadian withholding taxes attributable to payments of interest on the notes
unless such U.S. Holder has foreign source income in the same category as that
to which the interest income is allocated. Interest income generally will
constitute "passive income" (or "financial services income" for some U.S.
Holders) for U.S. foreign tax credit purposes. If, however, such withholding tax
is imposed at a rate of 5% or more, such income will constitute "high
withholding tax interest". The rules governing the foreign tax credit are
complex, and investors are urged to consult their tax advisors regarding the
availability of the credit under their particular circumstances.

ORIGINAL ISSUE DISCOUNT

         It is not expected that the notes will be issued with original issue
discount ("OID"). If, however, the notes are issued with more than a de minimis
amount of OID, then such OID would be treated for U.S. federal income tax
purposes as accruing over the notes' term as interest income of the U.S.
Holders. A U.S. Holder's adjusted tax basis in a note would be increased by the
amount of any original issue discount included in its gross income. In
compliance with United States Treasury regulations, if we determine that the
notes have original issue discount, we will provide certain information to the
IRS and/or U.S. Holders that is relevant to determining the amount of original
issue discount in each accrual period.

SALE, EXCHANGE OR RETIREMENT OF THE NOTES

         Upon the sale, exchange or retirement of a note, a U.S. Holder
generally will recognize a taxable gain or loss equal to the difference between
the amount realized on such sale, exchange, retirement, or redemption (reduced
by any amounts attributable to accrued but unpaid interest, which will be
taxable as ordinary income) and the U.S. Holder's adjusted tax basis in the
note. Such gain or loss generally will constitute a long term capital gain or
loss if the note was held by such U.S. Holder for more than one year and
otherwise will be short term capital gain or loss. Under current law, net
capital gains of non-corporate taxpayers (including individuals) are, under some
circumstances, taxed at lower rates than items of ordinary income. The
deductibility of capital losses is subject to limitations. In the case of a U.S.
Holder who is a United States resident (as defined in Section 865 of the Code),
any such gain or loss will be treated as U.S. source, unless it is attributable
to an office or other fixed place of business outside the United States and
certain other conditions are met.


                                       S-20


NON-U.S. HOLDERS

         The rules governing U.S. federal income taxation of Non-U.S. Holders
are complex and no attempt is made herein to provide more than a summary of
those rules. Non-U.S. Holders should consult with their own tax advisors to
determine the effect of federal, state, local and foreign income tax laws, as
well as treaties, with regard to an investment in the notes, including any
reporting requirements.

PAYMENT OF INTEREST

         Subject to the discussion below concerning backup withholding, payments
of interest (including OID) on the notes by us or our paying agent to any
Non-U.S. Holder will not be subject to U.S. federal withholding tax, provided
that:

         o        such holder (i) does not own, actually or constructively, 10%
                  or more of the total combined voting power of all classes of
                  the voting stock of the parent of the U.S. Group, (ii) is not
                  a controlled foreign corporation related, directly or
                  indirectly, to the parent of the U.S. Group through stock
                  ownership and (iii) is not a bank receiving interest described
                  in Section 881(c)(3)(A) of the Code; and

         o        the certification requirement, as described below, has been
                  fulfilled with respect to the beneficial owner.

         The certification requirement referred to above will be fulfilled if
either (A) the Non-U.S. Holder provides to us or our paying agent an IRS Form
W-8BEN (or successor form), signed under penalties of perjury, that includes
such holder's name and address and certifies as to its non-U.S. status or (B) a
securities clearing organization, bank or other financial institution that holds
customers' securities in the ordinary course of its trade or business, and holds
the note on behalf of the beneficial owner, provides a statement to us or our
paying agent signed under penalties of perjury in which the organization, bank
or financial institution certifies that an IRS Form W-8BEN (or successor form)
has been received by it from the Non-U.S. Holder or from another financial
institution acting on behalf of the Non-U.S. Holder and furnishes us or our
paying agent with a copy. Other methods might be available to satisfy the
certification requirements described above, depending upon the circumstances
applicable to the Non-U.S. Holder.

         We will withhold U.S. federal withholding tax at a rate of 30% on the
gross amount of payments of interest (including OID) that do not qualify for the
exception from withholding described above (the "portfolio interest exemption")
unless (i) the Non-U.S. Holder provides us with a properly-executed IRS Form
W-8BEN (or successor form) claiming an exemption from or reduction in
withholding under an applicable tax treaty or (ii) such interest (including OID)
is effectively connected with the conduct of a United States trade or business
by such Non-U.S. Holder and a properly-executed IRS Form W-8ECI (or successor
form) is provided to us or our paying agent.

         If a Non-U.S. Holder is engaged in a trade or business in the United
States and if interest (including OID) on the note or gain realized on the
disposition of the note is effectively connected with such trade or business,
then the Non-U.S. Holder generally will be subject to regular U.S. federal
income tax on such interest (including OID) or gain on a net basis in the same
manner as if it were a U.S. Holder, unless an applicable tax treaty provides
otherwise. If the Non-U.S. Holder is a foreign corporation, it may also be
subject to a branch profits tax at a rate of 30%, unless reduced or eliminated
by an applicable tax treaty. Even though such effectively connected income is
subject to income tax, and may be subject to the branch profits tax, it is not
subject to withholding tax if the Non-U.S. Holder satisfies the certification
requirements described above.

SALE, EXCHANGE OR DISPOSITION OF THE NOTES

         Subject to the discussion below concerning backup withholding, a
Non-U.S. Holder of a note will not be subject to U.S. federal income tax on gain
realized on the sale, exchange or other taxable disposition of such note,
unless:

         o        such holder is an individual who is present in the United
                  States for 183 days or more in the taxable year of disposition
                  and certain other conditions are met;

         o        such gain is effectively connected with the conduct of a
                  United States trade or business by such Non-U.S. Holder; or

         o        such gain represents accrued but unpaid interest not
                  previously included in income or OID, in which case the rules
                  for interest would apply.


                                       S-21


U.S. FEDERAL ESTATE TAX

         The notes will not be included in the estate of a deceased Non-U.S.
Holder for U.S. federal estate tax purposes if interest on the notes is exempt
from withholding of U.S. federal income tax under the portfolio interest
exemption (without regard to the certification requirement).

INFORMATION REPORTING AND BACKUP WITHHOLDING

         If you are a U.S. Holder, in general, information reporting
requirements may apply to payments of interest on the notes (including OID)
unless you are an exempt recipient (such as a corporation). Backup withholding
tax will apply to such payments if you fail to provide your taxpayer
identification number or certification of foreign or other exempt status or fail
to report in full dividend and interest income.

         If you are a Non-U.S. Holder, in general, you will not be subject to
backup withholding and information reporting with respect to payments that we
make to you provided that we do not have actual knowledge or reason to know that
you are a U.S. person and you have given us the statement described above under
"--Non-U.S. Holders-- Payments of Interest". In addition, you will not be
subject to backup withholding or information reporting with respect to the
proceeds of the sale of a note within the United States or conducted through
certain U.S.-related financial intermediaries, if the payor receives the
statement described above and does not have actual knowledge or reason to know
that you are a U.S. person, as defined under the Code, or you otherwise
establish an exemption. However, we may be required to report annually to the
IRS and to you the amount of, and the tax withheld respect to, any interest paid
to you, regardless of whether any tax was actually withheld. Copies of these
information returns may also be made available under the provisions of a
specific treaty or agreement to the tax authorities of the country in which the
Non-U.S. Holder resides.

         Any amounts withheld under the backup withholding rules will be allowed
as a refund or a credit against your U.S. federal income tax liability provided
the required information is furnished timely to the IRS.

         THE FOREGOING DISCUSSION IS FOR GENERAL INFORMATION ONLY AND IS NOT TAX
ADVICE. ACCORDINGLY, YOU SHOULD CONSULT YOUR TAX ADVISOR AS TO THE PARTICULAR
TAX CONSEQUENCES TO YOU OF PURCHASING, HOLDING AND DISPOSING OF THE NOTES,
INCLUDING THE APPLICABILITY AND EFFECT OF ANY STATE, LOCAL OR NON-U.S. TAX LAWS
AND ANY RECENT OR PROPOSED CHANGES IN APPLICABLE TAX LAWS.

         In the underwriting agreement, the several underwriters have agreed,
subject to the terms and conditions set forth therein, to purchase all the notes
offered hereby if any of the notes are purchased. In the event of default by an
underwriter, the underwriting agreement provides that, in certain circumstances,
purchase commitments of the non-defaulting underwriters may be increased or the
purchase agreement may be terminated. The obligations of the underwriters under
the underwriting agreement may also be terminated upon the occurrence of certain
stated events.

         We and the Guarantor have agreed to indemnify the several underwriters
against certain liabilities, including liabilities under the Securities Act, or
to contribute to payments the underwriters may be required to make in respect of
those liabilities.

         The underwriters are offering the notes, subject to prior sale, when,
as and if issued to and accepted by them, subject to approval of legal matters
by their counsel, including the validity of the notes, and other conditions
contained in the underwriting agreement, such as the receipt by the underwriters
of officer's certificates and legal opinions. The underwriters reserve the right
to withdraw, cancel or modify offers to the public and to reject orders in whole
or in part.

         The representatives have advised us that the underwriters propose
initially to offer the notes to the public at the public offering price set
forth on the cover of this prospectus supplement and to certain dealers at that
price less a concession not to exceed 0.40% of the principal amount of the
notes. The underwriters may allow, and such dealers may reallow, a discount not
to exceed 0.25% of the principal amount of the notes on sales to certain other
dealers. After the initial public offering, the public offering price,
concession and discount may be changed by the underwriters.

         The expenses of the offering, not including the underwriting
commission, are estimated to be US$1.0 million and are payable by us.

         We and the Guarantor have agreed not to, prior to the closing of this
offering, directly or indirectly, offer, sell, contract to sell or otherwise
dispose of any debt securities which mature more than one year after the closing
of this offering and which are substantially similar to the notes, without first
obtaining the prior written consent of the representatives of the underwriters.

         The notes are a new issue of securities with no established trading
market. We do not intend to apply for listing of the notes on any national
securities exchange or for quotation of the notes on any automated dealer
quotation system. We have been advised by the


                                       S-23


underwriters that they presently intend to make a market in the notes after
completion of the offering. However, they are under no obligation to do so and
may discontinue any market-making activities at any time without any notice. We
cannot assure the liquidity of the trading market for the notes or that an
active public market for the notes will develop. If an active public trading
market for the notes does not develop, the market price and liquidity of the
notes may be adversely affected.

         The underwriters have performed certain investment banking and advisory
services for the Guarantor from time to time for which they have received
customary fees and expenses. The underwriters may, from time to time, engage in
transactions with and perform services for us or the Guarantor in the ordinary
course of their business. Also, certain of the underwriters are affiliates of
banks which are lenders to the Guarantor and to which the Guarantor is currently
indebted. As a consequence of their participation in the offering, the
underwriters affiliated with such banks will be entitled to share in the
underwriting commission relating to the offering of the notes. The decision to
distribute the notes hereunder and the determination of the terms of this
offering were made through negotiations among us, the Guarantor and the
underwriters. Although the banks did not have any involvement in such decision
or determination, a portion of the proceeds of the offering may ultimately be
used to repay indebtedness to fourteen of such banks and may be used to repay
certain other lenders. As a result, such banks may receive more than 10% of the
net proceeds from the offering of the notes in the form of the repayment of such
indebtedness. Accordingly, the offering of the notes is being made pursuant to
Rule 2710(h) of the Conduct Rules of the National Association of Securities
Dealers, Inc. Pursuant to that rule, the appointment of a qualified independent
underwriter is not necessary in connection with this offering, as the offering
is of a class of securities rated BBB or better by S&P's rating service or Baa
or better by Moody's rating service.

         Certain of the underwriters will make the notes available for
distribution on the internet though a third-party system operated by Market
Axess Inc., an internet-based communications technology provider. Market Axess
Inc. is providing the system for communications between such underwriters and
their customers and is not a party to any transactions. Market Axess Inc., a
registered broker-dealer, will receive compensation from certain of the
underwriters based on transactions they conduct through the system. Such
underwriters will make the notes available to their customers through the
internet distributions on the same terms as distributions made through other
channels.

         In connection with the offering, the underwriters are permitted to
engage in transactions that stabilize the market price of the notes. Such
transactions consist of bids or purchases to peg, fix or maintain the price of
the notes. If the underwriters create a short position in the notes in
connection with the offering (i.e., if they sell more notes than are on the
cover page of this prospectus supplement) the underwriters may reduce that short
position by purchasing notes in the open market. Purchases of a security to
stabilize the price or to reduce a short position could cause the price of the
security to be higher than it might be in the absence of such purchases.

         Neither we nor any of the underwriters makes any representation or
prediction as to the direction or magnitude of any effect that the transactions
described above may have on the price of the notes. In addition, neither we nor
any of the underwriters makes any representation that the underwriters will
engage in these transactions or that these transactions, once commenced, will
not be discontinued without notice.

                                  LEGAL MATTERS

         Certain legal matters relating to Canadian law will be passed upon for
us and the Guarantor by Macleod Dixon LLP, Calgary, Alberta, Canada. Certain
legal matters relating to United States law will be passed upon for us by Paul,
Weiss, Rifkind, Wharton & Garrison LLP, New York, New York. In addition, certain
legal matters relating to United States law will be passed upon for the
underwriters by Shearman & Sterling LLP, Toronto, Ontario, Canada.

                              ABOUT THIS PROSPECTUS

     All references in this prospectus and any prospectus supplement to "EnCana
Holdings Finance", "we", "us" and "our" mean EnCana Holdings Finance Corp.
Except as set forth under "Description of Debt Securities", and unless the
context otherwise requires, all references to "EnCana" and "the Guarantor" means
EnCana Corporation and its consolidated subsidiaries and partnerships.

     In this prospectus and in any prospectus supplement, unless otherwise
specified or the context otherwise requires, all dollar amounts are expressed in
United States dollars, references to "dollars", "$" or "US$" are to United
States dollars and all references to "C$" are to Canadian dollars. Unless
otherwise indicated, all financial information included and incorporated by
reference in this prospectus or included in any prospectus supplement is
determined using Canadian generally accepted accounting principles, referred to
as "Canadian GAAP".

     This prospectus is part of a registration statement on Form F-9 relating to
the debt securities that we filed with the U.S. Securities and Exchange
Commission (the "SEC"). We may, from time to time, sell any combination of the
debt securities described in this prospectus in one or more offerings up to an
aggregate principal amount of US$2,000,000,000. This prospectus provides you
with a general description of the debt securities that we may offer. Each time
we sell debt securities under this prospectus, we will provide a prospectus
supplement that will contain specific information about the terms of that
offering of debt securities. The prospectus supplement may also add, update or
change information contained in this prospectus. Before you invest, you should
read both this prospectus and any applicable prospectus supplement together with
additional information described under the heading "Where You Can Find More
Information". THIS PROSPECTUS DOES NOT CONTAIN ALL OF THE INFORMATION SET FORTH

WITH RESPECT TO US AND THE DEBT SECURITIES.

                       WHERE YOU CAN FIND MORE INFORMATION

     As at the date hereof, we do not directly satisfy the eligibility criteria
required to be able to file a prospectus in the form of a short form prospectus
or utilize the shelf procedures under Canadian securities legislation. However,
because the Guarantor will fully and unconditionally guarantee the payments to
be made by us in connection with the debt securities, and the Guarantor
satisfies the prescribed eligibility criteria, we are qualified to avail
ourselves of the short form and shelf prospectus provisions of Canadian
securities legislation. As required by Canadian securities legislation, various
disclosure documents filed by the Guarantor under applicable securities
legislation are incorporated by reference herein.

     INFORMATION HAS BEEN INCORPORATED BY REFERENCE IN THIS PROSPECTUS FROM
DOCUMENTS FILED WITH SECURITIES COMMISSIONS OR SIMILAR AUTHORITIES IN CANADA.
Copies of the documents incorporated herein by reference may be obtained on
request without charge from the Corporate Secretary of EnCana Corporation, 1800,
855 -- 2nd Street S.W., P.O. Box 2850, Calgary, Alberta T2P 2S5, Canada,
telephone: (403) 645-2000. For the purpose of the Province of Quebec, this
simplified prospectus contains information to be completed by consulting the
permanent information record. A copy of the permanent information record may be
obtained from the Corporate Secretary of EnCana Corporation at the
above-mentioned address and telephone number. These documents are also available
through the internet via the System for Electronic Document Analysis and
Retrieval (SEDAR), which can be accessed at www.sedar.com.

     The Guarantor files with the securities commission or authority in each of
the provinces and territories of Canada annual and quarterly reports, material
change reports and other information. The Guarantor is subject to the


                                        2


informational requirements of the United States Securities Exchange Act of 1934,
as amended (the "Exchange Act") and, in accordance with the Exchange Act, it
also files reports with and furnishes other information to the SEC. Under a
multijurisdictional disclosure system adopted by the United States, these
reports and other information (including financial information) may be prepared
in accordance with the disclosure requirements of Canada, which differ from
those in the United States. You may read any document we or the Guarantor
furnish to the SEC at the SEC's public reference room at Room 1024, 450 Fifth
Street, N.W., Washington, D.C. 20549. You may also obtain copies of the same
documents from the public reference room of the SEC at 450 Fifth Street, N.W.,
Washington D.C. 20549 by paying a fee. Please call the SEC at 1-800-SEC-0330 or
contact them at www.sec.gov for further information on the public reference
rooms. The Guarantor's filings since November 2002 are also electronically
available from the SEC's Electronic Document Gathering and Retrieval System,
which is commonly known by the acronym EDGAR and which may be accessed at
www.sec.gov, as well as from commercial document retrieval services.

     We do not intend to file with Canadian securities regulatory authorities
separate continuous disclosure information apart from, where there is a material
change in our business, operations or capital that is not a material change in
respect of the Guarantor, a material change report. We have made application for
exemptions from all remaining continuous disclosure requirements contained
within the securities legislation of each of the provinces of Canada and expect
to be granted decisions of the securities regulatory authorities of each of
those jurisdictions to that effect (the "Decisions"). We expect the Decisions to
provide in part that we shall be entitled to file, in lieu of such continuous
disclosure filings, certain filings of the Guarantor made with the Canadian
securities regulatory authorities.

     Under applicable securities laws in Canada and the United States, the
Canadian securities commissions and the SEC allow us to incorporate by reference
certain information that the Guarantor files with them, which means that we can
disclose important information to you by referring you to those documents.
Information that is incorporated by reference is an important part of this
prospectus. We incorporate by reference the documents listed below, which were
filed with the Canadian securities commissions under the Canadian securities
legislation:

                           FORWARD-LOOKING STATEMENTS

     Certain statements included in this prospectus and the documents
incorporated by reference herein constitute forward looking statements within
the meaning of the United States Private Securities Litigation Reform Act of
1995 relating to, but not limited to, the operations, anticipated financial
performance, business prospects and strategies of EnCana (including the U.S.
Group, as hereinafter defined). Forward looking statements typically contain
statements with words such as "anticipate", "believe", "expect", "plan",
"intend" or similar words suggesting future outcomes or statements regarding an
outlook on crude oil and natural gas prices, estimates of future production,
reserves and resources, the estimated amounts and timing of capital
expenditures, anticipated future debt levels and royalty rates, or other
expenditures, beliefs, plans, objectives, assumptions or statements about future
events or performance.

     You are cautioned not to place undue reliance on forward looking
statements. By their nature, forward looking statements involve numerous
assumptions, inherent risks and uncertainties, both general and specific, that
contribute to the possibility that the predicted outcomes will not occur. These
factors include, but are not limited to:

     o   general economic, business and market conditions;

     o   volatility of crude oil, natural gas and natural gas liquids prices;

     o   fluctuations in currency and interest rates, product supply and demand;

     o   competition;

     o   risks inherent in foreign operations, including political and economic
         risk;

     o   risks of war, hostilities, civil insurrection and terrorist threats;

     o   risks inherent in marketing operations including credit risks;

     o   imprecision of reserve estimates;

     o   EnCana's ability to replace or expand reserves;

     o   EnCana's ability to either generate sufficient cash flow to meet
         current and future obligations or to obtain external debt or equity
         financing;

     o   EnCana's ability to enter into or renew leases;

     o   the timing and costs of pipeline and natural gas storage facility
         construction and expansion;

     o   EnCana's ability to make capital investments and the amounts thereof;

     o   imprecision in estimating future production capacity, and the timing,
         costs and levels of production and drilling;

     o   results of EnCana's exploration, development and drilling activity;

     o   EnCana's ability to secure adequate product transportation;

     o   changes in regulations, including environmental regulations;

     o   risks associated with existing and potential future lawsuits and
         regulatory actions against EnCana;

     o   uncertainty in amounts and timing of royalty payments; and

     o   imprecision in estimating product sales.

     We caution that the foregoing list of important factors is not exhaustive.
Events or circumstances could cause our or the Guarantor's actual results to
differ materially from those estimated or projected and expressed in, or implied
by, these forward looking statements. You should also carefully consider the
matters discussed under "Risk Factors" in the prospectus. Neither we nor EnCana
Corporation undertake any obligation to update publicly or otherwise revise any
forward looking statements, whether as a result of new information, future
events or otherwise, or the foregoing list of factors affecting this
information.

                          ENCANA HOLDINGS FINANCE CORP.

     We are an unlimited liability company incorporated on August 25, 2003 under
the laws of the province of Nova Scotia, Canada. We are a wholly owned indirect
subsidiary of EnCana Corporation. Our principal executive offices are located at
1800, 855 -- 2nd Street S.W., Calgary, Alberta T2P 2S5, Canada and our
registered offices are located at Suite 800, 1959 Upper Water St., P.O. Box 997,
Halifax, Nova Scotia, B3J 2X2.

     We are part of a group of EnCana's subsidiaries and partnerships which
carry on substantially all of EnCana's operations in the United States (the
"U.S. Group"). We have been established for the purpose of raising financing for
the U.S. Group. We have no subsidiaries and, except as aforesaid, have no active
business.

     Unless otherwise indicated in the applicable prospectus supplement relating
to a series of debt securities, we will advance the net proceeds we receive from
the sale of the debt securities to one or more other corporations or
partnerships within the U.S. Group, by way of loan, for their use for the
general corporate purposes of the U.S. Group. See "Use of Proceeds". The U.S.
Group is involved in both upstream and midstream operations. The upstream
operations of the U.S. Group are currently focused on exploiting deep, tight,
long-life natural gas formations primarily in the Jonah sweet natural gas field
located in the Green River Basin of southwest Wyoming and the Mamm Creek natural
gas field located in the Piceance Basin of northwest Colorado. The U.S. Group
also explores for, develops and produces natural gas and crude oil in other
areas, including north Texas, the Gulf of Mexico and Alaska. The U.S. Group's
midstream operations include an extensive natural gas storage network with
facilities in California and Oklahoma, as well as various natural gas gathering
and processing assets.

     The funds required by us to satisfy our obligations under the debt
securities we issue under this prospectus will be obtained through our debt
interests in other members of the U.S. Group or through other advances from
EnCana Corporation or its subsidiaries or partnerships. Any debt securities we
issue under this prospectus will be fully and unconditionally guaranteed by
EnCana Corporation.

                               ENCANA CORPORATION

     EnCana Corporation is one of the world's leading independent crude oil and
natural gas exploration and production companies, based on landholdings and
production at December 31, 2003. EnCana's key landholdings are in Western
Canada, the U.S. Rocky Mountains, Ecuador, the United Kingdom ("U.K.") central
North Sea, offshore Canada's East Coast and the Gulf of Mexico. It explores for,
produces and markets natural gas, crude oil and natural gas liquids ("NGLs") in
Canada and the United States. EnCana is also engaged in exploration and
production activities internationally including production from Ecuador and the
U.K. central North Sea. EnCana has interests in midstream operations and assets,
including natural gas storage, NGLs gathering and processing facilities, power
plants and pipelines.

     EnCana continually pursues opportunities to develop and expand its
business, which may include significant corporate or asset acquisitions. EnCana
may finance such acquisitions with debt or equity, or a combination of both.

     EnCana was formed through the business combination (the "Merger") of
PanCanadian Energy Corporation ("PanCanadian") and Alberta Energy Company Ltd.
("AEC") on April 5, 2002. Pursuant to the Merger, PanCanadian indirectly
acquired all of the outstanding common shares of AEC and PanCanadian's name was
changed to EnCana Corporation. Effective January 1, 2003, EnCana Corporation
amalgamated with its wholly owned subsidiary, AEC, and continued as one entity.
As a result of the amalgamation, EnCana Corporation is the successor issuer in
respect of AEC's previously issued debt securities and is responsible for all of
AEC's contractual obligations.

     EnCana Corporation's principal executive and registered offices are located
at 1800, 855 -- 2nd Street S.W., Calgary, Alberta T2P 2S5, Canada.

                                 USE OF PROCEEDS

     Unless otherwise indicated in the applicable prospectus supplement relating
to a series of debt securities, we will advance the net proceeds we receive from
the sale of the debt securities to one or more other corporations or
partnerships within the U.S. Group, by way of loan, for their use for general
corporate purposes of the U.S. Group. Those general corporate purposes may
include capital expenditures, the repayment of indebtedness and the financing of
acquisitions. The amount of net proceeds to be used for any such purpose will be
described in an applicable prospectus supplement.

                         DESCRIPTION OF DEBT SECURITIES

     In this section only, "EnCana Corporation" and "the Guarantor" refer only
to EnCana Corporation without any of its subsidiaries or partnerships through
which it operates. The following description describes certain general terms and
provisions of the debt securities. We will provide the particular terms and
provisions of a series of debt securities and a description of how the general
terms and provisions described below may apply to that series in a supplement to
this prospectus.

     The debt securities will be issued under an indenture (hereinafter referred
to as the "Indenture") to be entered into among us, the Guarantor and Deutsche
Bank Trust Company Americas, as "Trustee". The Indenture will be subject to and
governed by the U.S. Trust Indenture Act of 1939, as amended. A copy of the form
of Indenture has been filed as an exhibit to the registration statement filed
with the SEC. The following is a summary of the Indenture which describes
certain general terms and provisions of the debt securities and is not intended
to be complete; these statements are qualified in their entirety by, and subject
to, the provisions of the Indenture, including the definition of capitalized
terms used under this caption. We urge you to read the Indenture carefully,
because it is the Indenture, and not this summary, that governs your rights as a
holder of our debt securities. See "Where You Can Find More Information" in this
prospectus. Prospective investors should rely on information in the applicable
prospectus supplement, which may provide information that is different from this
prospectus.

     We may, from time to time, issue debt instruments and incur additional
indebtedness other than through the issuance of debt securities pursuant to this
prospectus.

GENERAL

     The Indenture does not limit the aggregate principal amount of debt
securities (which may include debentures, notes and other unsecured evidences of
indebtedness) that we may issue under the Indenture. It provides that debt
securities may be issued from time to time in one or more series and may be
denominated and payable in U.S. dollars or any foreign currency. Special
Canadian and U.S. federal income tax considerations applicable to any of our
debt securities denominated in a foreign currency will be described in the
prospectus supplement relating to any offering of debt securities denominated in
a foreign currency. The debt securities offered pursuant to this prospectus will
be issued in an amount up to US$2,000,000,000, or if any debt securities are
offered at original issue discount, such greater amount as shall result in an
aggregate offering price of up to US$2,000,000,000 or the equivalent in other
currencies. The Indenture also permits us to increase the principal amount of
any series of our debt securities previously issued and to issue that increased
principal amount. The applicable prospectus supplement will set forth the
following terms relating to the debt securities being offered by us:

     o   the specific designation and the aggregate principal amount of the debt
         securities of such series;

     o   the extent and manner, if any, to which payment on or in respect of our
         debt securities of such series will be senior or will be subordinated
         to the prior payment of our other liabilities and obligations;

     o   the percentage or percentages of principal amount at which our debt
         securities of such series will be issued;

     o   the date or dates on which the principal of (and premium, if any, on)
         our debt securities of such series will be payable and the portion (if
         less than the principal amount) of the debt securities of such series
         to be payable upon a declaration of acceleration of maturity and/or the
         method by which such date or dates shall be determined or extended;

     o   the rate or rates (whether fixed or variable) at which our debt
         securities of such series will bear interest, if any, and the date or
         dates from which such interest will accrue;

     o   the dates on which any interest will be payable and the regular record
         dates for the payment of interest on our debt securities of such series
         in registered form;

     o   the place or places where the principal of (and premium, if any, and
         interest, if any, on) our debt securities will be payable, and each
         office or agency where our debt securities of such series may be
         presented for registration of transfer or exchange;

     o   if other than U.S. dollars, the currency in which our debt securities
         of such series are denominated or in which currency payment of the
         principal of (and premium, if any, and interest, if any, on) such debt
         securities of such series will be payable;


                                        7


     o   whether our debt securities of such series will be issuable in the form
         of one or more global securities and, if so, the identity of the
         depositary for the global securities;

     o   any mandatory or optional redemption or sinking fund provisions;

     o   the period or periods, if any, within which, the price or prices at
         which, the currency in which and the terms and conditions upon which
         our debt securities of such series may be redeemed or purchased by us;

     o   the terms and conditions, if any, upon which you may redeem our debt
         securities of such series prior to maturity and the price or prices at
         which and the currency in which our debt securities of such series are
         payable;

     o   any index used to determine the amount of payments of principal of (and
         premium, if any, or interest, if any, on) our debt securities of such
         series;

     o   the terms, if any, on which our debt securities may be converted or
         exchanged for other of our debt securities or debt securities of other
         entities;

     o   any other terms of our debt securities of such series, including
         covenants and events of default which apply solely to a particular
         series of our debt securities being offered which do not apply
         generally to other debt securities, or any covenants or events of
         default generally applicable to our debt securities of such series
         which do not apply to a particular series of our debt securities;

     o   if other than The Depository Trust Company, the person designated as
         the depositary for the debt securities of such series;

     o   any applicable material Canadian and U.S. federal income tax
         consequences;

     o   whether and under what circumstances we will pay Additional Amounts on
         the debt securities of such series in respect of certain taxes (and the
         terms of any such payment) and, if so, whether we will have the option
         to redeem the debt securities of such series rather than pay the
         Additional Amounts (and the terms of any such option);

     o   whether the payment of our debt securities will be guaranteed by any
         other person in addition to the Guarantor;

     o   whether the series of our debt securities are to be registered
         securities, bearer securities (with or without coupons) or both; and

     o   if other than denominations of US$1,000 and any integral multiple
         thereof, the denominations in which any registered securities of the
         series shall be issuable and, if other than the denomination of
         US$5,000, the denomination or denominations in which any bearer
         securities of the series shall be issuable.

     Unless otherwise indicated in the applicable prospectus supplement, the
Indenture does not afford holders of our debt securities the right to tender
such debt securities to us in the event that we have a change in control.

     Our debt securities may be issued under the Indenture bearing no interest
or at a discount below their stated principal amount. The Canadian and U.S.
federal income tax consequences and other special considerations applicable to
any such discounted debt securities or other debt securities offered and sold at
par which are treated as having been issued at a discount for Canadian and/or
U.S. federal income tax purposes will be described in the prospectus supplement
relating to the debt securities.

GUARANTEE

     The Guarantor will fully and unconditionally guarantee the payment of the
principal (and premium, if any) and interest, if any, on the debt securities
issued by us and any Additional Amounts payable with respect to such debt
securities when they become due and payable, whether at the stated maturity
thereof or by declaration of acceleration, notice of redemption or otherwise.

RANKING

     Unless otherwise indicated in an applicable prospectus supplement, the debt
securities will be our unsecured and unsubordinated obligations and will rank
equally with all of our other unsecured and unsubordinated indebtedness
outstanding from time to time.


                                        8


     The guarantee will be the Guarantor's unsubordinated and unsecured
obligation and, unless otherwise provided with respect to a series of debt
securities, will rank equally with all of the Guarantor's other unsecured,
unsubordinated obligations. The Guarantor conducts a substantial portion of its
business through corporate and partnership subsidiaries. The Guarantor's
obligations under the guarantee will be structurally subordinate to all existing
and future indebtedness and liabilities of any of the Guarantor's corporate and
partnership subsidiaries.

FORM, DENOMINATIONS AND EXCHANGE

     A series of our debt securities may be issued solely as registered
securities, solely as bearer securities or as both registered securities and
bearer securities. The Indenture also provides that a series of our debt
securities may be issuable in global form. Registered securities will be
issuable in denominations of US$1,000 and integral multiples of US$1,000 and
bearer securities will be issuable in denominations of US$5,000 or, in each
case, in such other denominations as may be set out in the terms of the debt
securities of any particular series. Unless otherwise indicated in the
applicable prospectus supplement, bearer securities will have interest coupons
attached.

     A prospectus supplement may indicate the places to register a transfer of
our debt securities. Except for certain restrictions set forth in the Indenture,
no service charge will be made for any registration of transfer or exchange of
our debt securities, but we may, in certain instances, require a sum sufficient
to cover any tax or other governmental charges payable in connection with these
transactions.

     We shall not be required to:

     o   issue, register the transfer of or exchange any series of our debt
         securities during a period beginning at the opening of business 15 days
         before any selection of that series of our debt securities to be
         redeemed and ending at the close of business on (i) if the series of
         our debt securities are issuable only as registered securities, the day
         of mailing of the relevant notice of redemption and (ii) if the series
         of our debt securities are issuable as bearer securities, the day of
         the first publication of the relevant notice of redemption or, if the
         series of our debt securities are also issuable as registered
         securities and there is no publication, the mailing of the relevant
         notice of redemption;

     o   register the transfer of or exchange any registered security, or
         portion thereof, called for redemption, except the unredeemed portion
         of any registered security being redeemed in part;

     o   exchange any bearer security selected for redemption, except that, to
         the extent provided with respect to such bearer security, such bearer
         security may be exchanged for a registered security of that series and
         like tenor, PROVIDED that such registered security shall be immediately
         surrendered for redemption with written instruction for payment
         consistent with the provisions of the Indenture; or

     o   issue, register the transfer of or exchange any of our debt securities
         which have been surrendered for repayment at the option of the holder,
         except the portion, if any, thereof not to be so repaid.

PAYMENT

     Unless otherwise indicated in the applicable prospectus supplement, payment
of principal of (and premium, if any, and interest, if any, on) our debt
securities (other than global securities) will be made at the office or agency
of the Trustee.

     Unless otherwise indicated in the applicable prospectus supplement, payment
of any interest will be made to the persons in whose name our debt securities
are registered at the close of business on the day or days specified by us.

GLOBAL SECURITIES

     A series of our debt securities may be issued in whole or in part in global
form as a "global security" and will be registered in the name of and be
deposited with a depositary, or its nominee, each of which will be identified in
the prospectus supplement relating to that series. Unless and until exchanged,
in whole or in part, for our debt securities in definitive registered form, a
global security may not be transferred except as a whole by the depositary for
such global security to a nominee of the depositary, by a nominee of the
depositary to the depositary or another nominee of the depositary or by the
depositary or any such nominee to a successor of the depositary or a nominee of
the successor.


                                        9


     The specific terms of the depositary arrangement with respect to any
portion of a particular series of our debt securities to be represented by a
global security will be described in a prospectus supplement relating to such
series. We anticipate that the following provisions will apply to all depositary
arrangements.

     Upon the issuance of a global security, the depositary therefor or its
nominee will credit, on its book entry and registration system, the respective
principal amounts of our debt securities represented by the global security to
the accounts of such persons, designated as "participants", having accounts with
such depositary or its nominee. Such accounts shall be designated by the
underwriters, dealers or agents participating in the distribution of our debt
securities or by us if such debt securities are offered and sold directly by us.
Ownership of beneficial interests in a global security will be limited to
participants or persons that may hold beneficial interests through participants.
Ownership of beneficial interests in a global security will be shown on, and the
transfer of that ownership will be effected only through, records maintained by
the depositary therefor or its nominee (with respect to interests of
participants) or by participants or persons that hold through participants (with
respect to interests of persons other than participants). The laws of some
states in the United States may require that certain purchasers of securities
take physical delivery of such securities in definitive form.

     So long as the depositary for a global security or its nominee is the
registered owner of the global security, such depositary or such nominee, as the
case may be, will be considered the sole owner or holder of the debt securities
represented by the global security for all purposes under the Indenture. Except
as provided below, owners of beneficial interests in a global security will not
be entitled to have a series of our debt securities represented by the global
security registered in their names, will not receive or be entitled to receive
physical delivery of such series of our debt securities in definitive form and
will not be considered the owners or holders thereof under the Indenture.

     Any payments of principal, premium, if any, and interest on global
securities registered in the name of a depositary or its nominee will be made to
the depositary or its nominee, as the case may be, as the registered owner of
the global security representing such debt securities. None of us, the
Guarantor, the Trustee or any paying agent for our debt securities represented
by the global securities will have any responsibility or liability for any
aspect of the records relating to or payments made on account of beneficial
ownership interests of the global security or for maintaining, supervising or
reviewing any records relating to such beneficial ownership interests.

     We expect that the depositary for a global security or its nominee, upon
receipt of any payment of principal, premium, if any, or interest, will credit
participants' accounts with payments in amounts proportionate to their
respective beneficial interests in the principal amount of the global security
as shown on the records of such depositary or its nominee. We also expect that
payments by participants to owners of beneficial interests in a global security
held through such participants will be governed by standing instructions and
customary practices, as is now the case with securities held for the accounts of
customers registered in "street name", and will be the responsibility of such
participants.

     If a depositary for a global security representing a particular series of
our debt securities is at any time unwilling or unable to continue as depositary
and a successor depositary is not appointed by us within 90 days, we will issue
such series of our debt securities in definitive form in exchange for a global
security representing such series of our debt securities. In addition, we may at
any time and in our sole discretion determine not to have a series of our debt
securities represented by a global security and, in such event, will issue a
series of our debt securities in definitive form in exchange for all of the
global securities representing the series of debt securities.

         (ii) above, and (iv) indebtedness incurred by the Guarantor or any of
         its Subsidiaries to refinance indebtedness incurred for the purposes

         assets which was secured by the prior Lien plus improvements on such
         property or assets and (ii) the indebtedness, if any, secured by the
         new Lien is not increased from the amount of the indebtedness secured

     "RESTRICTED SUBSIDIARY" means, on any date, any Subsidiary of the Guarantor

vote accruing to shares of another class or classes by reason of the happening
of such an event, or solely because the right to vote may not be exercisable
under the charter of the corporation.


                                       13


COVENANTS

LIMITATION ON LIENS

     The Indenture provides that so long as any of our debt securities are
outstanding and subject to the provisions of the Indenture, the Guarantor will
not, and will not permit any of its Restricted Subsidiaries to, create, incur,
assume or otherwise have outstanding any Lien securing any indebtedness for
borrowed money or interest thereon (or any liability of the Guarantor or such
Restricted Subsidiaries under the related guarantee or endorsement or other
instrument under which the Guarantor or such Restricted Subsidiaries are
contingently liable, either directly or indirectly, for borrowed money or
interest thereon), other than Permitted Liens, without also simultaneously or
prior thereto securing, or causing such Restricted Subsidiaries to secure,
indebtedness under the Indenture so that our debt securities are secured equally
and ratably with or prior to such other indebtedness, except that the Guarantor
and its Restricted Subsidiaries may incur a Lien to secure indebtedness for
borrowed money without securing our debt securities if, after giving effect
thereto, the principal amount of indebtedness for borrowed money secured by
Liens created, incurred or assumed after the date of the Indenture and otherwise
prohibited by the Indenture does not exceed 10% of the Guarantor's Consolidated
Net Tangible Assets.

     Notwithstanding the foregoing, transactions such as the sale (including any
forward sale) or other transfer of (i) oil, gas, minerals or other resources of
a primary nature, whether in place or when produced, for a period of time until,
or in an amount such that, the purchaser will realize therefrom a specified
amount of money or a specified rate of return (however determined), or a
specified amount of such oil, gas, minerals, or other resources of a primary
nature, or (ii) any other interest in property of the character commonly
referred to as a "production payment", will not constitute a Lien and will not
result in the Guarantor or a Restricted Subsidiary being required to secure the
debt securities.

CONSOLIDATION, AMALGAMATION, MERGER AND SALE OF ASSETS

     Neither we nor the Guarantor may consolidate or amalgamate with or merge
into or enter into any statutory arrangement with any other corporation, or
convey, transfer or lease all or substantially all our or the Guarantor's, as
the case may be, properties and assets to any person, unless:

     o   the entity formed by or continuing from such consolidation or
         amalgamation or into which we or the Guarantor (as the case may be) are
         merged or with which we or the Guarantor (as the case may be) enter
         into such statutory arrangement or the person which acquires or leases
         all or substantially all of our or the Guarantor's properties and
         assets (as the case may be) is organized and existing under the laws of
         the United States, any state thereof or the District of Columbia or the
         laws of Canada or any province or territory thereof, or, if such
         consolidation, amalgamation, merger, statutory arrangement or other
         transaction would not impair the rights of the holders of our debt
         securities, in any other country, PROVIDED that if such successor
         entity is organized under the laws of a jurisdiction other than the
         United States, any state thereof or the District of Columbia, or the
         laws of Canada or any province or territory thereof, the successor
         entity assumes our or the Guarantor's obligations (as the case may be)
         under the debt securities and the Indenture to pay Additional Amounts,
         with the name of such successor jurisdiction being included in addition
         to Canada in each place that Canada appears in "--Payment of Additional
         Amounts" below;

     o   the successor entity expressly assumes or assumes by operation of law
         all of our or the Guarantor's obligations (as the case may be) under
         our debt securities, the guarantee and the Indenture;

     o   immediately before and after giving effect to such transaction, no
         event of default, and no event which, after notice or lapse of time or
         both, would become an event of default, shall have happened and be
         continuing; and

     o   certain other conditions are met.

     If, as a result of any such transaction, any of the Guarantor's or its
Restricted Subsidiaries' Restricted Properties become subject to a Lien, then,
unless such Lien could be created pursuant to the Indenture provisions described
under the "LIMITATION ON LIENS" covenant above without equally and ratably
securing our debt securities, the Guarantor, simultaneously with or prior to
such transaction, will secure, or cause the applicable Restricted Subsidiary to
secure, our debt securities equally and ratably with or prior to the
indebtedness secured by such Lien.


                                       14


PAYMENT OF ADDITIONAL AMOUNTS

     Unless otherwise specified in the applicable prospectus supplement, all
payments made by or on behalf of us or the Guarantor under or with respect to
any series of our debt securities or related guarantee will be made free and
clear of and without withholding or deduction for or on account of any present
or future tax, duty, levy, impost, assessment or other governmental charge
(including penalties, interest and other liabilities related thereto) imposed or
levied by or on behalf of the Government of Canada or any province or territory
thereof or by any authority or agency therein or thereof having power to tax
(hereinafter "Canadian Taxes"), unless we or the Guarantor, as the case may be,
are required to withhold or deduct Canadian Taxes by law or by the
interpretation or administration thereof. If we or the Guarantor, as the case
may be, are so required to withhold or deduct any amount for or on account of
Canadian Taxes from any payment made under or with respect to the debt
securities or guarantee, we or the Guarantor, as the case may be, will pay to
each holder of such debt securities as additional interest such additional
amounts ("Additional Amounts") as may be necessary so that the net amount
received by each such holder after such withholding or deduction (and after
deducting any Canadian Taxes on such Additional Amounts) will not be less than
the amount such holder would have received if such Canadian Taxes had not been
withheld or deducted. However, no Additional Amounts will be payable with
respect to a payment made to a debt securities holder (such holder, an "Excluded
Holder") in respect of the beneficial owner thereof:

     o   with which we or the Guarantor, as the case may be, do not deal at
         arm's length (for the purposes of the INCOME TAX ACT (Canada)) at the
         time of the making of such payment;

     o   which is subject to such Canadian Taxes by reason of the debt
         securities holder being a resident, domicile or national of, or engaged
         in business or maintaining a permanent establishment or other physical
         presence in or otherwise having some connection with Canada or any
         province or territory thereof otherwise than by the mere holding of the
         debt securities or the receipt of payments thereunder; or

     o   which is subject to such Canadian Taxes by reason of the debt
         securities holder's failure to comply with any certification,
         identification, documentation or other reporting requirements if
         compliance is required by law, regulation, administrative practice or
         an applicable treaty as a precondition to exemption from, or a
         reduction in the rate of deduction or withholding of, such Canadian
         Taxes.

     We or the Guarantor, as the case may be, will also:

     o   make such withholding or deduction; and

     o   remit the full amount deducted or withheld to the relevant authority in
         accordance with applicable law.

     We or the Guarantor, as the case may be, will furnish to the holders of the
debt securities, within 60 days after the date the payment of any Canadian Taxes
is due pursuant to applicable law, certified copies of tax receipts or other
documents evidencing such payment by us or the Guarantor, as the case may be.

     We and the Guarantor will indemnify and hold harmless each holder of debt
securities (other than an Excluded Holder) and upon written request reimburse
each such holder for the amount (excluding any Additional Amounts that have
previously been paid by us or the Guarantor with respect thereto) of:

     o   the payment of any Canadian Tax, together with any interest, penalties
         and reasonable expenses in connection therewith; and

     o   any Canadian Taxes imposed with respect to any reimbursement under the
         preceding clause, but excluding any such Canadian Taxes on such
         holder's net income.

     In any event, no Additional Amounts or indemnity amounts will be payable in
excess of Additional Amounts or the indemnity amounts which would be required if
the holder of debt securities was a resident of the United States for purposes
of the Canada-U.S. Income Tax Convention (1980), as amended.

     Wherever in the Indenture, the debt securities or the guarantee there is
mentioned, in any context, the payment of principal (and premium, if any),
interest, if any, or any other amount payable under or with respect to a debt
security or guarantee, such mention shall be deemed to include mention of the
payment of Additional Amounts to the extent that, in such context, Additional
Amounts are, were or would be payable in respect thereof.


                                       15


TAX REDEMPTION

     Unless otherwise specified in the applicable prospectus supplement, a
series of our debt securities will be subject to redemption at any time, in
whole but not in part, at a redemption price equal to the principal amount
thereof together with accrued and unpaid interest to the date fixed for
redemption, upon the giving of a notice as described below, if:

     o   as a result of any change in or amendment to the laws (or any
         regulations or rulings promulgated thereunder) of Canada or of any
         political subdivision or taxing authority thereof or therein affecting
         taxation, or any change in official position regarding the application
         or interpretation of such laws, regulations or rulings (including a
         holding by a court of competent jurisdiction), which change or
         amendment is announced or becomes effective on or after the date
         specified in the applicable prospectus supplement, we have or will
         become obligated to pay (or the Guarantor has or will become obligated
         to pay, as the case may be) on the next succeeding date on which
         interest is due, Additional Amounts with respect to any debt security
         of such series as described under "--Payment of Additional Amounts"; or

     o   on or after the date specified in the applicable prospectus supplement,
         any action has been taken by any taxing authority of, or any decision
         has been rendered by a court of competent jurisdiction in Canada, or
         any political subdivision or taxing authority thereof or therein,
         including any of those actions specified in the paragraph immediately
         above, whether or not such action was taken or decision was rendered
         with respect to us (or the Guarantor, as the case may be), or any
         change, amendment, application or interpretation shall be officially
         proposed, which, in any such case, in the written opinion to us (or the
         Guarantor, as the case may be) of legal counsel of recognized standing,
         will result in our (or the Guarantor, as the case may be) becoming
         obligated to pay, on the next succeeding date on which interest is due,
         Additional Amounts with respect to any debt security of such series;

and, in any such case, we, in our business judgment, or the Guarantor, in its
business judgment, as the case may be, determine that such obligation cannot be
avoided by the use of reasonable measures available to us.

     In the event that we elect to redeem a series of our debt securities
pursuant to the provisions set forth in the preceding paragraph, we shall
deliver to the Trustee a certificate, signed by an authorized officer, stating
that we are entitled to redeem such series of our debt securities pursuant to
their terms.

     Notice of intention to redeem such series of our debt securities will be
given not more than 60 nor less than 30 days prior to the date fixed for
redemption and will specify the date fixed for redemption.

PROVISION OF FINANCIAL INFORMATION

     The Guarantor will file with the Trustee, within 15 days after it files
them with the SEC, copies, which may be in electronic format, of its annual
report and of the information, documents and other reports (or copies of such
portions of any of the foregoing as the SEC may by rules and regulations
prescribe) which it is required to file with the SEC pursuant to Section 13 or
15(d) of the Exchange Act. Notwithstanding that the Guarantor may not be
required to remain subject to the reporting requirements of Section 13 or 15(d)
of the Exchange Act or otherwise report on an annual and quarterly basis on
forms provided for such annual and quarterly reporting pursuant to rules and
regulations promulgated by the SEC, the Guarantor will continue to provide the
Trustee:

     o   within 140 days after the end of each fiscal year, the information
         required to be contained in annual reports on Form 20-F, Form 40-F or
         Form 10-K as applicable (or any successor form); and

     o   within 65 days after the end of each of the first three fiscal quarters
         of each fiscal year, the information required to be contained in
         reports on Form 6-K (or any successor form) which, regardless of
         applicable requirements shall, at a minimum, contain such information
         required to be provided in quarterly reports under the laws of Canada
         or any province thereof to security holders of a corporation with
         securities listed on the Toronto Stock Exchange, whether or not the
         Guarantor has any of its securities listed on such exchange. Such
         information will be prepared in accordance with Canadian disclosure
         requirements and GAAP; PROVIDED, HOWEVER, that the Guarantor shall not
         be obligated to file such report with the SEC if the SEC does not
         permit such filings.


                                       16


EVENTS OF DEFAULT

     The following are summaries of events of default under the Indenture with
respect to any series of our debt securities:

     o   default in the payment of any interest on any debt security of that
         series when it becomes due and payable, and continuance of such default
         for a period of 30 days;

     o   default in the payment of the principal of (or premium, if any, on),
         any debt security of that series when it becomes due and payable;

     o   default in the performance, or breach, of any of our or the Guarantor's
         covenants or warranties in the Indenture in respect of our debt
         securities of that series (other than a covenant or warranty a default
         in the performance of which or the breach of which is specifically
         dealt with elsewhere in the Indenture), and continuance of such default
         or breach for a period of 60 days after receipt by us and the Guarantor
         of written notice, specifying such default or breach, by the Trustee or
         by the holders of at least 25% in principal amount of all outstanding
         debt securities of any series affected thereby;

     o   if an event of default (as defined in any indenture or instrument under
         which we, or the Guarantor, or any of its Restricted Subsidiaries, has
         at the time of the Indenture or shall thereafter have outstanding any
         indebtedness for borrowed money) shall happen and be continuing, or we,
         or the Guarantor, or any Restricted Subsidiary shall have failed to pay
         principal amounts with respect to such indebtedness at maturity and
         such event of default or failure to pay shall result in such
         indebtedness being declared due and payable or otherwise being
         accelerated, in either event so that an amount in excess of the greater
         of US$75,000,000 and 2% of the Guarantor's Shareholders' Equity shall
         be or become due and payable upon such declaration or otherwise
         accelerated prior to the date on which the same would otherwise have
         become due and payable (the "accelerated indebtedness"), and such
         acceleration shall not be rescinded or annulled, or such event of
         default or failure to pay under such indenture or instrument shall not
         be remedied or cured, whether by payment or otherwise, or waived by the
         holders of such accelerated indebtedness, then (i) if the accelerated
         indebtedness shall be as a result of an event of default which is not
         related to the failure to pay principal or interest on the terms, at
         the times, and on the conditions set out in any such indenture or
         instrument, it shall not be considered an event of default for purposes
         of the Indenture until 30 days after such indebtedness has been
         accelerated, or (ii) if the accelerated indebtedness shall occur as a
         result of such failure to pay principal or interest or as a result of
         an event of default which is related to the failure to pay principal or
         interest on the terms, at the times, and on the conditions set out in
         any such indenture or instrument, then (A) if such accelerated
         indebtedness is, by its terms, Non-Recourse Debt to us, the Guarantor
         or its Restricted Subsidiaries, it shall not be considered an event of
         default for purposes of the Indenture; or (B) if such accelerated
         indebtedness is recourse to us, the Guarantor or its Restricted
         Subsidiaries, any requirement in connection with such failure to pay or
         event of default for the giving of notice or the lapse of time or the
         happening of any further condition, event or act under such other
         indenture or instrument in connection with such failure to pay
         principal or an event of default shall be applicable together with an
         additional seven days before being considered an event of default for
         purposes of the Indenture;

     o   certain events in bankruptcy, insolvency or reorganization; or

     o   any other events of default provided with respect to debt securities of
         that series.

     If an event of default under the Indenture occurs and is continuing with
respect to any series of our debt securities, then and in every such case the
Trustee or the holders of at least 25% in aggregate principal amount of the
outstanding debt securities of such affected series may, subject to any
subordination provisions thereof, declare the entire principal amount (or, if
the debt securities of that series are original issue discount debt securities,
such portion of the principal amount as may be specified in the terms of that
series) of all debt securities of such series and all accrued and unpaid
interest thereon to be immediately due and payable. However, at any time after a
declaration of acceleration with respect to any series of our debt securities
has been made, but before a judgment or decree for payment of the money due has
been obtained, the holders of a majority in principal amount of the outstanding
debt securities of that series, by written notice to us, the Guarantor and the
Trustee under certain circumstances, may rescind and annul such acceleration.


                                       17


     Reference is made to the applicable prospectus supplement or supplements
relating to each series of our debt securities which are original issue discount
debt securities for the particular provisions relating to acceleration of the
maturity of a portion of the principal amount of such original issue discount
securities upon the occurrence of any event of default and the continuation
thereof.

     Subject to certain limitations set forth in the Indenture, the holders of a
majority in principal amount of the outstanding debt securities of all series
affected by an event of default shall have the right to direct the time, method
and place of conducting any proceeding for any remedy available to the Trustee,
or exercising any trust or power conferred on the Trustee, with respect to the
debt securities of all series affected by such event of default.

     No holder of a debt security of any series will have any right to institute
any proceeding with respect to the Indenture, or for the appointment of a
receiver or a Trustee, or for any other remedy thereunder, unless:

     o   such holder has previously given to the Trustee written notice of a
         continuing event of default with respect to the debt securities of such
         series affected by such event of default;

     o   the holders of at least 25% in aggregate principal amount of the
         outstanding debt securities of such series (voting as one class)
         affected by such event of default have made written request, and such
         holder or holders have offered reasonable indemnity, to the Trustee to
         institute such proceeding as Trustee; and

     o   the Trustee has failed to institute such proceeding, and has not
         received from the holders of a majority in aggregate principal amount
         of the outstanding debt securities of such series affected by such
         event of default a direction inconsistent with such request, within 60
         days after such notice, request and offer.

     However, such above-mentioned limitations do not apply to a suit instituted
by the holder of a debt security for the enforcement of payment of the principal
of or any premium or interest on such debt security on or after the applicable
due date specified in such debt security.

     We and the Guarantor will annually furnish to the Trustee a statement by
certain of our and the Guarantor's officers as to whether or not we and the
Guarantor, to the best of their knowledge, are in compliance with all conditions
and covenants of the Indenture and, if not, specifying all such known defaults.

DEFEASANCE AND COVENANT DEFEASANCE

     Unless otherwise specified in the applicable prospectus supplement, the
Indenture provides that, at our or the Guarantor's option, we and the Guarantor
will be discharged from any and all obligations in respect of the outstanding
debt securities of any series upon irrevocable deposit with the Trustee, in
trust, of money and/or government securities which will provide money in an
amount sufficient in the opinion of a nationally recognized firm of independent
chartered accountants (as evidenced by an officer's certificate delivered to the
Trustee) to pay the principal of (and premium, if any, and each installment of
interest, if any, on) the outstanding debt securities of such series
(hereinafter referred to as a "defeasance") (except with respect to the
authentication, transfer, exchange or replacement of our debt securities or the
maintenance of a place of payment and certain other obligations set forth in the
Indenture). Such trust may only be established if among other things:

     o   we or the Guarantor have delivered to the Trustee an opinion of counsel
         in the United States stating that (i) we or the Guarantor have received
         from, or there has been published by, the Internal Revenue Service a
         ruling, or (ii) since the date of execution of the Indenture, there has
         been a change in the applicable U.S. federal income tax law, in either
         case to the effect that the holders of the outstanding debt securities
         of such series will not recognize income, gain or loss for U.S. federal
         income tax purposes as a result of such defeasance and will be subject
         to U.S. federal income tax on the same amounts, in the same manner and
         at the same times as would have been the case if such defeasance had
         not occurred;

     o   we or the Guarantor have delivered to the Trustee an opinion of counsel
         in Canada or a ruling from the Canada Revenue Agency to the effect that
         the holders of the outstanding debt securities of such series will not
         recognize income, gain or loss for Canadian federal or provincial
         income or other tax purposes as a result of such Defeasance and will be
         subject to Canadian federal or provincial income and other tax on the
         same amounts, in the same manner and at the same times as would have
         been the case had such defeasance not occurred (and for the purposes of
         such opinion, such Canadian counsel shall assume that holders of the
         outstanding debt securities of such series include holders who are not
         resident in Canada);


                                       18


     o   no event of default or event that, with the passing of time or the
         giving of notice, or both, shall constitute an event of default shall
         have occurred and be continuing on the date of such deposit; and

     o   neither we nor the Guarantor is an "insolvent person" within the
         meaning of the BANKRUPTCY AND INSOLVENCY ACT (Canada) on the date of
         such deposit or at any time during the period ending on the 91st day
         following such deposit.

     We or the Guarantor may exercise the defeasance option notwithstanding the
prior exercise of the Covenant Defeasance option described in the following
paragraph if the conditions described in the preceding sentence are met at the
time we or the Guarantor exercise the defeasance option.

     The Indenture provides that, at our or the Guarantor's option, unless and
until we have exercised our Defeasance option described in the preceding
paragraph, we or the Guarantor, as applicable, may omit to comply with the
"LIMITATION ON LIENS" covenant, certain aspects of the "CONSOLIDATION,
AMALGAMATION, MERGER AND SALE OF ASSETS" covenant and certain other covenants
and such omission shall not be deemed to be an event of default under the
Indenture and the outstanding debt securities and guarantee upon irrevocable
deposit with the Trustee, in trust, of money and/or government securities which
will provide money in an amount sufficient in the opinion of a nationally
recognized firm of independent chartered accountants (as evidenced by an
officer's certificate delivered to the Trustee) to pay the principal of (and
premium, if any, and each installment of interest, if any, on) the outstanding
debt securities (hereinafter referred to as "covenant defeasance"). If we or the
Guarantor exercise the covenant defeasance option, the obligations under the
Indenture other than with respect to such covenants and the events of default
other than with respect to such covenants shall remain in full force and effect.
Such trust may only be established if, among other things:

     o   we or the Guarantor have delivered to the Trustee an opinion of counsel
         in the United States to the effect that the holders of the outstanding
         debt securities will not recognize income, gain or loss for U.S.
         federal income tax purposes as a result of such covenant defeasance and
         will be subject to U.S. federal income tax on the same amounts, in the
         same manner and at the same times as would have been the case if such
         covenant defeasance had not occurred;

     o   we or the Guarantor have delivered to the Trustee an opinion of counsel
         in Canada or a ruling from the Canada Revenue Agency to the effect that
         the holders of the outstanding debt securities will not recognize
         income, gain or loss for Canadian federal or provincial income or other
         tax purposes as a result of such covenant defeasance and will be
         subject to Canadian federal or provincial income and other tax on the
         same amounts, in the same manner and at the same times as would have
         been the case had such covenant defeasance not occurred (and for the
         purposes of such opinion, such Canadian counsel shall assume that
         holders of the outstanding debt securities include holders who are not
         resident in Canada);

     o   no event of default or event that, with the passing of time or the
         giving of notice, or both, shall constitute an event of default shall
         have occurred and be continuing on the date of such deposit; and

     o   neither we nor the Guarantor is an "insolvent person" within the
         meaning of the BANKRUPTCY AND INSOLVENCY ACT (Canada) on the date of
         such deposit or at any time during the period ending on the 91st day
         following such deposit.

MODIFICATION AND WAIVER

     Modifications and amendments of the Indenture may be made by us, the
Guarantor and the Trustee with the consent of the holders of a majority in
principal amount of the outstanding debt securities of each series issued under
the Indenture affected by such modification or amendment (voting as one class);
PROVIDED, HOWEVER, that no such modification or amendment may, without the
consent of the holder of each outstanding debt security of such affected series:

     o   change the stated maturity of the principal of, or any installment of
         interest, if any, on any debt security;

     o   reduce the principal amount of (or premium, if any, or interest, if
         any, on) any debt security;

     o   reduce the amount of principal of a debt security payable upon
         acceleration of the maturity thereof;

     o   change the place of payment;

     o   change the currency of payment of principal of (or premium, if any, or
         interest, if any, on) any debt security;


                                       19


     o   impair the right to institute suit for the enforcement of any payment
         on or with respect to any debt security;

     o   reduce the percentage of principal amount of outstanding debt
         securities of such series, the consent of the holders of which is
         required for modification or amendment of the applicable Indenture or
         for waiver of compliance with certain provisions of the Indenture or
         for waiver of certain defaults; or

     o   modify any provisions of the Indenture relating to the modification and
         amendment of the Indenture or the waiver of past defaults or covenants
         except as otherwise specified in the Indenture.

     The holders of a majority in principal amount of our outstanding debt
securities of any series may on behalf of the holders of all debt securities of
that series waive, insofar as that series is concerned, compliance by us or the
Guarantor with certain restrictive provisions of the Indenture. The holders of a
majority in principal amount of outstanding debt securities of any series may
waive any past default under the Indenture with respect to that series, except a
default in the payment of the principal of (or premium, if any) and interest, if
any, on any debt security of that series or in respect of a provision which
under the Indenture cannot be modified or amended without the consent of the
holder of each outstanding debt security of that series. The Indenture or the
debt securities may be amended or supplemented, without the consent of any
holder of such debt securities, in order to, among other things, cure any
ambiguity or inconsistency or to make any change, in any case, that does not
have a materially adverse effect on the rights of any holder of such debt
securities.

CONSENT TO JURISDICTION AND SERVICE

     Under the Indenture, we and the Guarantor irrevocably appoint CT
Corporation System, 111 -- 8th Avenue, 13th Floor, New York, New York, as our
and the Guarantor's authorized agent for service of process in any suit or
proceeding arising out of or relating to the debt securities or the Indenture
and for actions brought under federal or state securities laws in any federal or
state court located in New York, New York and irrevocably submit to the
non-exclusive jurisdiction of any such court.

GOVERNING LAW

     Our debt securities and the Indenture will be governed by and construed in
accordance with the laws of the State of New York.

ENFORCEABILITY OF JUDGMENTS

     Since most of the Guarantor's assets, as well as the assets of a number of
our and the Guarantor's directors and officers, are outside the United States,
any judgment obtained in the United States against us, the Guarantor or certain
of our or the Guarantor's directors or officers, including judgments with
respect to the payment of principal on any debt securities, may not be
collectible within the United States.

     We have been informed by Macleod Dixon LLP, our and the Guarantor's
Canadian counsel, that the laws of the Province of Alberta and the federal laws
of Canada applicable therein permit an action to be brought in a court of
competent jurisdiction in the Province of Alberta on any final and conclusive IN
PERSONAM judgment of any federal or state court located in the State of New York
(a "New York Court") against us, which judgment is subsisting and unsatisfied
for a sum certain with respect to the enforcement of the Indenture and the debt
securities that is not impeachable as void or voidable under the internal laws
of the State of New York if: (i) the New York Court rendering such judgment had
jurisdiction over the judgment debtor, as recognized by the courts of the
Province of Alberta (and submission by us in the Indenture to the jurisdiction
of the New York Court will be sufficient for that purpose); (ii) such judgment
was not obtained by fraud or in a manner contrary to natural justice and the
enforcement thereof would not be inconsistent with public policy, as such terms
are understood under the laws of the Province of Alberta or contrary to any
order made by the Attorney General of Canada under the FOREIGN EXTRATERRITORIAL
MEASURES ACT (Canada) or by the Competition Tribunal under the COMPETITION ACT
(Canada); (iii) the enforcement of such judgment would not be contrary to the
laws of general application limiting the enforcement of creditors' rights
including bankruptcy, reorganization, winding up, moratorium and similar laws
and does not constitute, directly or indirectly, the enforcement of foreign
revenue, expropriatory or penal laws in the Province of Alberta; (iv) no new
admissible evidence relevant to the action is discovered prior to the rendering
of judgment by the court in the Province of Alberta; (v) interest payable on the
debt securities is not characterized by a court in the Province of Alberta as
interest payable at a criminal rate within the meaning of Section 347 of


                                       20


the CRIMINAL CODE (Canada); and (vi) the action to enforce such judgment is
commenced within the appropriate limitation period, except that any court in the
Province of Alberta may only give judgment in Canadian dollars.

     In the opinion of such counsel, there are no reasons under present laws of
the Province of Alberta for avoiding recognition of such judgments of New York
Courts under the Indenture or on the debt securities based upon public policy.
We have been advised by suchcounsel that there is doubt as to the enforceability
in Canada by a court in original actions, or in actions to enforce judgments of
United States courts, of civil liabilities predicated solely upon the United
States federal securities laws.

     Because the Trustee is located in the United States, it may not be possible
for purchasers of our debt securities outside the United States to effect
service of process outside the United States upon the Trustee nor to enforce
against the Trustee, outside the United States, judgments obtained in courts
outside the United States. Also, it may not be possible to enforce judgments of
non-U.S. courts against the Trustee in the United States.


                                       21


                                  RISK FACTORS

     You should consider carefully the risk factors set forth below as well as
the other information contained in and incorporated by reference in this
prospectus and in the applicable prospectus supplement before purchasing the
debt securities. If any event arising from these risks occurs, the business,
prospects, financial condition, results of operation or cash flows of EnCana
(including the U.S. Group) could be materially adversely affected.

A SUBSTANTIAL OR EXTENDED DECLINE IN CRUDE OIL AND NATURAL GAS PRICES COULD HAVE
A MATERIAL ADVERSE EFFECT ON ENCANA.

     EnCana's financial condition is substantially dependent on the prevailing
prices of crude oil and natural gas. Fluctuations in crude oil or natural gas
prices could have an adverse effect on EnCana's operations and financial
condition and the value and amount of EnCana's reserves. Prices for crude oil
and natural gas fluctuate in response to changes in the supply of and demand
for, crude oil and natural gas, market uncertainty and a variety of additional
factors beyond EnCana's control. Crude oil prices are determined by
international supply and demand. Factors which affect crude oil prices include
the actions of the Organization of Petroleum Exporting Countries, world economic
conditions, government regulation, political stability in the Middle East and
elsewhere, the foreign supply of crude oil, the price of foreign imports, the
availability of alternate fuel sources and weather conditions. Natural gas
prices realized by EnCana are affected primarily by North American supply and
demand, weather conditions and by prices of alternate sources of energy. Any
substantial or extended decline in the prices of crude oil and natural gas could
result in a delay or cancellation of existing or future drilling, development or
construction programs or curtailment in production at some properties or result
in unutilized long-term transportation commitments, all of which could have an
adverse effect on our revenues, profitability and cash flows.

     EnCana conducts an annual assessment of the carrying value of its assets in
accordance with Canadian GAAP. If crude oil and natural gas prices decline, the
carrying value of EnCana's assets could be subject to financial downward
revisions, and EnCana's earnings could be adversely affected.

IF ENCANA FAILS TO ACQUIRE OR FIND ADDITIONAL CRUDE OIL AND NATURAL GAS
RESERVES, ENCANA'S RESERVES AND PRODUCTION WILL DECLINE MATERIALLY FROM THEIR
CURRENT LEVELS.

     EnCana's future crude oil and natural gas reserves and production, and
therefore EnCana's cash flows, are highly dependent upon its success in
exploiting its current reserve base and acquiring or discovering additional
reserves. Without reserve additions through exploration, acquisition or
development activities, EnCana's reserves and production will decline over time
as reserves are depleted. The business of exploring for, developing or acquiring
reserves is capital intensive. To the extent cash flows from operations are
insufficient and external sources of capital become limited, EnCana's ability to
make the necessary capital investments to maintain and expand its crude oil and
natural gas reserves will be impaired. In addition, there can be no guarantee
that EnCana will be able to find and develop or acquire additional reserves to
replace production at acceptable costs.

ENCANA'S CRUDE OIL AND NATURAL GAS RESERVE DATA AND FUTURE NET REVENUE ESTIMATES
ARE UNCERTAIN.

     There are numerous uncertainties inherent in estimating quantities of crude
oil and natural gas reserves, including many factors beyond EnCana's control.
The reserve data incorporated herein represents estimates only. In general,
estimates of economically recoverable crude oil and natural gas reserves and the
future net cash flows therefrom are based upon a number of variable factors and
assumptions, such as product prices, future operating and capital costs,
historical production from the properties and the assumed effects of regulation
by governmental agencies, all of which may vary considerably from actual
results. All such estimates are to some degree uncertain, and classifications of
reserves are only attempts to define the degree of uncertainty involved. For
those reasons, estimates of the economically recoverable crude oil and natural
gas reserves attributable to any particular group of properties, classification
of such reserves based on risk of recovery and estimates of future net revenues
expected therefrom, prepared by different engineers or by the same engineers at
different times, may vary substantially. EnCana's actual production, revenues,
taxes and development and operating expenditures with respect to its reserves
may vary from such estimates, and such variances could be material.

     Estimates with respect to reserves that may be developed and produced in
the future are often based upon volumetric calculations and upon analogy to
similar types of reserves, rather than upon actual production history. Estimates
based on these methods generally are less reliable than those based on actual
production history.


                                       22


Subsequent evaluation of the same reserves based upon production history will
result in variations, which may be material, in the estimated reserves.

ENCANA DOES NOT OPERATE ALL OF ITS PROPERTIES AND ASSETS.

     Other companies operate some of the assets in which EnCana has interests.
As a result, EnCana has limited ability to exercise influence over operations of
these assets or their associated costs. EnCana's dependence on the operator and
other working interest owners for these properties and its limited ability to
influence operations and associated costs could materially adversely affect its
financial performance. The success and timing of EnCana's activities on assets
operated by others therefore will depend upon a number of factors that are
outside of its control, including:

     o   timing and amount of capital expenditures;

     o   the operator's expertise and financial resources;

     o   approval of other participants;

     o   selection of technology; and

     o   risk management practices.

ENCANA'S BUSINESS IS SUBJECT TO ENVIRONMENTAL LEGISLATION IN ALL JURISDICTIONS
IN WHICH IT OPERATES AND ANY CHANGES IN SUCH LEGISLATION COULD NEGATIVELY AFFECT
ENCANA'S RESULTS OF OPERATIONS.

     All phases of the crude oil and natural gas business are subject to
environmental regulation pursuant to a variety of Canadian, U.S. and other
federal, provincial, territorial, state and municipal laws and regulations
(collectively, "environmental legislation").

     Environmental legislation imposes, among other things, restrictions,
liabilities and obligations in connection with the generation, handling, use,
storage, transportation, treatment and disposal of hazardous substances and
waste and in connection with spills, releases and emissions of various
substances to the environment. Environmental legislation also requires that
wells, facility sites and other properties associated with our operations be
operated, maintained, abandoned and reclaimed to the satisfaction of applicable
regulatory authorities. In addition, certain types of operations, including
exploration and development projects and changes to certain existing projects,
may require the submission and approval of environmental impact assessments or
permit applications. Compliance with environmental legislation can require
significant expenditures, including expenditures for clean up costs and damages
arising out of contaminated properties and failure to comply with environmental
legislation may result in the imposition of fines and penalties. Although it is
not expected that the costs of complying with environmental legislation will
have a material adverse effect on EnCana's financial condition or results of
operations, no assurance can be made that the costs of complying with
environmental legislation in the future will not have such an effect.

     In 1994, the United Nations' Framework Convention on Climate Change came
into force and three years later led to the Kyoto Protocol (the "Protocol")
which requires, upon ratification, nations to reduce their emissions of carbon
dioxide and other greenhouse gases. In December 2002, the Canadian federal
government ratified the Protocol. If certain conditions are met and the Protocol
enters into force internationally, Canada will be required to reduce its
greenhouse gas (GHG) emissions. Currently the upstream crude oil and natural gas
sector is in discussions with various provincial and federal levels of
government regarding the development of greenhouse gas regulations for the
industry. It is premature to predict what impact these potential regulations
could have on EnCana's sector but it is possible that EnCana would face
increases in operating costs in order to comply with a GHG emissions target.

ENCANA MAY BE ADVERSELY AFFECTED BY LEGAL PROCEEDINGS RELATED TO ITS
DISCONTINUED MERCHANT ENERGY TRADING OPERATIONS.

     An action has been filed by E. & J. Gallo Winery in the United States
District Court, Eastern District of California, against EnCana Corporation and
its wholly-owned U.S. marketing subsidiary alleging that they engaged in a
conspiracy with unnamed competitors in the natural gas and derivatives market in
California in violation of U.S. and California anti-trust and unfair competition
laws to artificially raise the price of natural gas through various means
including the illegal sharing of price information through online trading, price
indexes and wash


                                       23


trading. The Gallo complaint claims damages in excess of US$30 million, before
potential trebling under California laws.

     In addition, EnCana Corporation and its wholly-owned U.S. marketing
subsidiary, along with other energy companies, have been named as defendants in
several class action lawsuits in California and New York federal and state
courts. The California lawsuits relate to sales of natural gas in California
from 1999 to the present and contain essentially similar allegations as in the
Gallo complaint. The New York lawsuits claim that the defendants' alleged
manipulation of natural gas price indexes resulted in higher prices of natural
gas futures and option contracts traded on the New York Mercantile Exchange
(NYMEX) during the period from January 1, 2000 to December 31, 2002. As is
customary, the class actions do not specify the amount of damages claimed. There
is no assurance that there will not be other actions arising out of these
allegations on behalf of the same or different classes.

     EnCana intends to vigorously defend against any claims of liability alleged
in these lawsuits; however, neither we nor EnCana can predict the outcome of
these proceedings or the commencement or outcome of any future proceedings
against EnCana or whether any such proceeding would lead to monetary damages
which could have a material adverse effect on EnCana's financial position.

ENCANA'S OPERATIONS ARE SUBJECT TO THE RISK OF BUSINESS INTERRUPTION AND
CASUALTY LOSSES.

     EnCana's business is subject to all of the operating risks normally
associated with the exploration for and production of crude oil and natural gas
and the operation of midstream facilities. These risks include blowouts,
explosions, fire, gaseous leaks, migration of harmful substances and crude oil
spills, any of which could cause personal injury, result in damage to, or
destruction of, crude oil and natural gas wells or formations or production
facilities and other property, equipment and the environment, as well as
interrupt operations. In addition, all of EnCana's operations are subject to all
of the risks normally incident to the transportation, processing and storing of
crude oil, natural gas and other related products, drilling of crude oil and
natural gas wells, and the operation and development of crude oil and natural
gas properties, including encountering unexpected formations or pressures,
premature declines of reservoirs, blowouts, equipment failures and other
accidents, sour gas releases, uncontrollable flows of crude oil, natural gas or
well fluids, adverse weather conditions, pollution and other environmental
risks.

     The occurrence of a significant event against which EnCana is not fully
insured could have a material adverse effect on EnCana's financial position.

ENCANA'S FOREIGN OPERATIONS WILL EXPOSE IT TO RISKS FROM ABROAD WHICH COULD
NEGATIVELY AFFECT ITS RESULTS OF OPERATIONS.

     Some of EnCana's operations and related assets are located in countries
outside North America, some of which may be considered to be politically and
economically unstable. Exploration or development activities in such countries
may require protracted negotiations with host governments, national oil
companies and third parties and are frequently subject to economic and political
considerations, such as taxation, nationalization, expropriation, inflation,
currency fluctuations, increased regulation and approval requirements,
governmental regulation and the risk of actions by terrorist or insurgent
groups, any of which could aversely affect the economics of exploration or
development projects.

ENCANA CORPORATION IS SUBJECT TO INDEMNIFICATION OBLIGATIONS IN CONNECTION WITH
PANCANADIAN'S SPIN-OFF FROM CANADIAN PACIFIC LIMITED.

     In connection with PanCanadian's spin-off from Canadian Pacific Limited
("CPL") on October 1, 2001, PanCanadian entered into an arrangement agreement
with certain other parties to the spin-off which contains a number of
representations, warranties and covenants, including (a) an agreement by each of
the parties to indemnify and hold harmless each other party on an after-tax
basis against any loss suffered or incurred resulting from a breach of a
representation, warranty or covenant; and (b) a covenant that each party will
not take any action, omit to take any action or enter into any transaction that
could adversely impact certain tax rulings received in connection with the
spin-off, including government opinions and related opinions of counsel and the
assumptions upon which they were made.


                                       24


     With respect to Canadian taxation, in addition to various transactions that
the respective parties were prohibited from undertaking prior to the
implementation of the CPL arrangement, after the implementation of the CPL
arrangement, no party generally is permitted to dispose of or exchange more than
10% of its assets or, among other things, undergo an acquisition of control
without severe adverse consequences where such disposition or acquisition of
control is for Canadian tax purposes part of a "series of transactions or
events" that includes the CPL arrangement, except in limited circumstances.

     Should EnCana Corporation be found to have breached its representations and
warranties or should it fail to satisfy the contractual covenants, it would be
obligated to indemnify the other parties to the arrangement agreement for losses
incurred in connection with such breach or failure. In addition, EnCana
Corporation is required to indemnify the parties to the arrangement agreement
against any loss which they may incur resulting from a claim against it, their
respective businesses or its respective assets, whether arising prior to or
after the completion of the CPL arrangement. An indemnification claim against us
pursuant to the provisions of the arrangement agreement could have a material
adverse effect upon us.

                              PLAN OF DISTRIBUTION

     We may sell debt securities to or through underwriters or dealers and also
may sell debt securities directly to purchasers or through agents. These debt
securities may be sold in Canada, the United States and elsewhere where
permitted by law.

     The distribution of debt securities of any series may be effected from time
to time in one or more transactions:

     o   at a fixed price or prices, which may be changed;

     o   at market prices prevailing at the time of sale; or

     o   at prices related to such prevailing market prices to be negotiated
         with purchasers.

     In connection with the sale of debt securities, underwriters may receive
compensation from us or from purchasers of debt securities for whom they may act
as agents in the form of concessions or commissions. Underwriters, dealers and
agents that participate in the distribution of debt securities may be deemed to
be underwriters and any commissions received by them from us and any profit on
the resale of debt securities by them may be deemed to be underwriting
commissions under the United States Securities Act of 1933, as amended (the
"Securities Act").

     The prospectus supplement relating to each series of debt securities will
also set forth the terms of the offering of the debt securities, including to
the extent applicable, the initial offering price, our proceeds from the
offering, the underwriting concessions or commissions, and any other discounts
or concessions to be allowed or reallowed to dealers. Underwriters with respect
to each series sold to or through underwriters will be named in the prospectus
supplement relating to such series.

     Under agreements which may be entered into by us and the Guarantor,
underwriters, dealers and agents who participate in the distribution of debt
securities may be entitled to indemnification by us or the Guarantor against
certain liabilities, including liabilities under the Securities Act. The
underwriters, dealers and agents with whom we and the Guarantor enter into
agreements may be customers of, engage in transactions with or perform services
for us or the Guarantor in the ordinary course of business.

     Each series of debt securities will be a new issue of securities with no
established trading market. Unless otherwise specified in a prospectus
supplement relating to a series of debt securities, the debt securities will not
be listed on any securities exchange or on any automated dealer quotation
system. Certain broker-dealers may make a market in the debt securities, but
will not be obligated to do so and may discontinue any market making at any time
without notice. We cannot assure you that any broker-dealer will make a market
in the debt securities of any series or as to the liquidity of the trading
market, if any, for the debt securities of any series.

                                INTEREST COVERAGE

     The following sets forth interest coverage ratios of the Guarantor
calculated for the twelve month period ended December 31, 2003 based on audited
financial information. The interest coverage ratios set out below have been
prepared and included in this prospectus in accordance with Canadian disclosure
requirements and have been calculated based on information prepared in
accordance with Canadian GAAP. The interest coverage ratios set out below do not
purport to be indicative of interest coverage ratios for any future periods. The
interest coverage ratios do not give effect to the debt securities offered by
this prospectus since the aggregate principal amount of debt securities that
will be issued hereunder and the terms of issue are not presently known.

                                                           DECEMBER 31, 2003
                                                           -----------------
                  Interest coverage on long-term debt:
                    Net earnings..........................    11.2 times
                    Cash flow.............................    16.7 times

     Interest coverage on long-term debt on a net earnings basis is equal to net
earnings before interest on long-term debt and income taxes divided by interest
expense on long-term debt. Interest coverage on long-term debt on a cash flow
basis is equal to cash flow before interest expense on long-term debt and cash
income taxes divided by interest expense on long-term debt. The Guarantor's net
earnings before interest on long-term debt and income taxes for the twelve
months ended December 31, 2003 was $3,145 million. For purposes of calculating
the interest coverage ratios set forth herein, long-term debt includes the
current portion of long-term debt.
