BURLINGTON RESOURCES FINANCE COMPANY
c/o Burlington Resources Canada Energy Ltd.
Suite 3700, 250-6th Avenue S.W.
Calgary, AB T2P 3H7Dear Sirs:

Re:  Burlington Resources Finance Company (the "Company") - Issue
     of 6.680% Notes Due 2011

We have acted as special Nova Scotia  counsel to the Company in  connection
with the creation,  issue and sale by the Company of U.S. $400,000,000 principal
amount of 6.680% notes due 2011 (the  "Offered  Securities")  pursuant to a Form
S-3 Registration Statement (the "Registration Statement"), filed with the United
States Securities and Exchange Commission.

The Offered  Securities  will be issued  pursuant to the  provisions  of an
indenture (the "Indenture") between the Company and Citibank, NA, as trustee.

We have considered such questions of law and examined such statutes,  public and
corporate records,  certificates of governmental authorities and officers of the
Company,  including a certificate of the Vice President and Assistant  Secretary
on behalf of the Company dated February 7, 2001 (the  "Officer's  Certificate"),
and other documents and conducted such other  examinations as we have considered
necessary  or desirable  to enable us to express the  opinions  hereinafter  set
forth.  In  such   examination  we  have  assumed  the  legal  capacity  of  all
individuals,  the veracity of the  information  contained in the documents,  the
genuineness of all signatures and the authenticity of all documents submitted to
us as  originals  and the  conformity  to  authentic  original  documents of all
documents  submitted to us as  certified,  conformed,  facsimile or  photostatic
copies of original documents.

In stating our opinions, we have also assumed

     a.   the  completeness,  truth  and  accuracy  of all  facts  set  forth in
          official public records and certificates and other documents  supplied
          by public officials; and

          contained in the Officer's Certificate.

                  We are solicitors qualified to practice law in the Province of
                  Nova Scotia and we express no opinion as to any laws or any
                  matters governed by any laws other than the laws of the
                  Province of Nova Scotia and the federal laws of Canada
                  applicable therein.

                  As to various questions of fact material to our opinion, which
                  we have not verified independently, we have relied upon
                  documents or certificates of governmental authorities and the
                  Company or its officers. In expressing the opinion in
                  paragraph (a) with respect to the valid existence of the
                  Company, we have relied exclusively on a Certificate of Status
                  issued under the Companies Act (Nova Scotia) dated on February
                  o, 2001, a copy of which has been provided to you.

                  On the basis of the foregoing we are of the opinion that:

               (a) The Company has been duly  incorporated,  is validly existing
          as a corporation in good standing  under the laws of the  jurisdiction
          of its incorporation

               (b) Subject to the execution and delivery of the Indenture by the
          Company,  the  Offered  Securities  have been duly  authorized  by the
          Company.

                  Consent is hereby given to the filing, as an exhibit to the
                  Registration Statement, of this letter. In giving such consent
                  we do not admit that we come within the category of persons
                  whose consent is required under Section 7 of the United States
                  Securities Act of 1933.

                  Yours truly,

                  /s/ STEWART MCKELVEY STIRLING SCALES
