                         Form 40-F (File No. 333-90736)


Dear Ms. Davis,

         Reference is made to comments to the Form 40-F (the "FORM 40-F") of
Western Oil Sands Inc., a Canadian corporation (the "COMPANY"), for the fiscal
year ended December 31, 2004 received from the Staff (the "STAFF") of the
Securities and Exchange Commission (the "COMMISSION") in a letter from the
Division of Corporation Finance, dated August 25, 2005 (the "COMMENT LETTER").
The discussion below is presented in the order of the numbered comments in the
Comment Letter and we have reproduced the comments for ease of reference.
Certain capitalized terms in this letter are used as defined in the Form 40-F.

The Company's responses to the Staff's comments are as follows:

         PAGE 3

         1.       WE HAVE READ YOUR RESPONSE TO PRIOR COMMENT THREE WHEREIN YOU
                  INDICATE THAT YOU SEPARATE FEEDSTOCKS AND TRANSPORTATION COSTS
                  INCURRED FROM REVENUES EARNED BECAUSE YOU BELIEVE THAT YOUR
                  SHAREHOLDERS ARE INTERESTED IN REVENUES BEING GENERATED BY
                  YOUR BITUMEN RESERVES. YOU ALSO INDICATE THAT YOU DO NOT
                  CONSIDER FEEDSTOCKS AND TRANSPORTATION TO BE OPERATING SINCE
                  THESE TYPES OF COSTS ARE "INCURRED TO EITHER MINE OR UPGRADE
                  THE BITUMEN INTO A SALEABLE PRODUCT". PLEASE PROVIDE AN
                  ANALYSIS THAT EXPLAINS HOW YOU HAVE CONSIDERED THE GUIDANCE IN
                  EIC 123 - REPORTING REVENUE GROSS AS A PRINCIPAL VERSUS NET AS
                  AN AGENT.



         Response to Comment 1:

         The presentation on the face of the Company's Consolidated Statements
         of Operations and Retained Earnings (Deficit) is as follows:

         -----------------------------------------------------------------------
         YEAR ENDED DECEMBER 31
         (THOUSANDS, EXCEPT AMOUNTS PER SHARE)                  2004        2003
         -----------------------------------------------------------------------

         REVENUES
            Revenue (Note 17)                             $  636,911  $  281,093
            Less Purchased Feedstocks and Transportation     315,236     117,580
                                                          ----------------------
                                                             320,985     163,513
         -----------------------------------------------------------------------

         Under EIC 123 revenue is required to be reported gross when the
         following conditions are met:

         o    The enterprise is the primary obligor in the arrangement.

         o    The enterprise has general inventory risk (before customer order
              is placed or upon customer return).

         o    The enterprise has latitude in establishing price.

         o    The enterprise changes the product or performs part of the
              service.

         o    The enterprise has discretion in supplier selection.

         o    The enterprise is involved in the determination of product or
              service specifications.

         o    The enterprise has physical loss inventory risk (after customer
              order or during shipping).

         o    The enterprise has credit risk.

         The Company has determined that its revenue stream, as described under
         the caption Revenue (Note 17), is to be reported gross as required
         under EIC 123 when circumstances agree to the above conditions. EIC 123
         does not, nor does any further Canadian Generally Accepted Accounting
         Principles, ("Canadian GAAP") preclude a sub-total being presented on
         the face of the Consolidated Statement of Operations and Retained
         Earnings (Deficit) which deducts certain amounts from gross revenue, as
         long as the gross number is presented. This was considered when the
         Company included both revenue and purchased feedstocks and
         transportation on the face of the Consolidated Statements of Operations
         and Retained Earnings (Deficit) in gross dollars, instead of netting
         the two and displaying only a single line on the face of the
         financials.

         Operating expenses are different from purchased feedstocks as operating
         expenses are costs incurred to either mine or upgrade bitumen into a
         saleable product. These costs include, but are not limited to, labour,
         fuel, natural gas, maintenance, electricity, catalysts, chemicals and
         property taxes. Purchased feedstocks are crude products that are
         introduced at the Upgrader, either into the hydrocracking/hydrotreating
         process or as a blendstock to create various qualities of synthetic
         crude oil products. The cost of feedstocks depends on world oil
         markets. The Company does not generate significant economic



         resources from the purchase of these feedstocks and the ultimate sale
         of these feedstocks as a portion of our synthetic crude oil.

         The transportation component of purchased feedstocks and transportation
         are the cost to get the Company's upgraded products from Edmonton to
         the final sales destination, which can be at a number of destinations
         in Canada and the United States. When the Company does sell its
         upgraded product downstream of Edmonton the sales price for that
         product is adjusted to reflect the additional costs and is therefore
         also included in revenue. The Company includes these costs in purchased
         feedstocks and transportation and displays a sub-total reflecting the
         difference between these costs and the revenue to provide a relevant
         presentation to the investor, as the sub-total better reflects the
         increase in economic resources to the Company as a result of its
         business operations, which is the mining, upgrading and sale of its
         bitumen resource from the Athabasca Oil Sands Project. The revenue
         caption does not provide this alone, as it can fluctuate depending on
         the cost of feedstocks and the geographic location where the Company
         sells its products.

         The Company also notes that the Auditor's Report that is attached to
         its financial statements states that "these consolidated financial
         statements present fairly, in all material respects, the financial
         position of Western Oil Sands Inc. as at December 31, 2004 and 2003 and
         the results of operations and its cash flows for the years then ended
         in accordance with Canadian Generally Accepted Accounting Principles",
         which would be inclusive of EIC 123.

         In light of the Staff's comment, the Company would be willing to modify
         its presentation of revenue and purchased feedstocks and transportation
         in its future quarterly and annual financial statements. The proposed
         presentation would remove the caption, Revenues, and instead have
         Revenue and Purchased Feedstocks and Transportation as separate
         captions, as displayed below:

         -----------------------------------------------------------------------
         YEAR ENDED DECEMBER 31
         (THOUSANDS, EXCEPT AMOUNTS PER SHARE)                2004         2003
         -----------------------------------------------------------------------

         REVENUE (NOTE 17)                             $   636,911  $   281,093
         LESS PURCHASED FEEDSTOCKS AND TRANSPORTATION      315,236      117,580
                                                       -------------------------

         CONSOLIDATED STATEMENT OF CASH FLOWS, PAGE 4

         2.       WE HAVE REVIEWED YOUR RESPONSE TO PRIOR COMMENT NUMBER FOUR
                  AND ARE UNABLE TO AGREE WITH YOU CONCLUSION. AS PREVIOUSLY
                  NOTED, THE ILLUSTRATIVE EXAMPLE IN CICA 1540 PRESENTS A
                  SUBTOTAL THAT DOES NOT INCLUDE NET INCOME OR LOSS, AND ONLY
                  INCLUDES "ITEMS NOT EFFECTING CASH". ACCORDINGLY, WE REISSUE
                  OUR PRIOR COMMENT IN ITS ENTIRETY.



                  WE NOTE IN YOUR RECONCILIATION OF NET EARNINGS TO NET CASH
                  PROVIDED BY OPERATING ACTIVITIES THAT YOU PRESENT A SUBTOTAL
                  OF NET INCOME AND VARIOUS CHARGES AND CREDITS ABOVE TOTAL NET
                  CASH FROM OPERATING ACTIVITIES. SUPPORT YOUR DISCLOSURE OF
                  THIS SUBTOTAL UNDER CANADIAN GAAP AS THERE DOES NOT APPEAR TO
                  BE A PROVISION WITHIN CICA 1540 FOR THIS PRESENTATION.

         Response to Comment 2:

         The example provided in CICA 1540 is provided as an illustrative
         example and not as authoritative guidance. In the Company's view
         Canadian GAAP requires that the companies utilizing the indirect method
         for presenting cash flow from operating activities present a total
         including the effects of any change in non-cash working capital.
         However Canadian GAAP does not prohibit the presentation of a sub-total
         that does not include the effect of any change in non-cash working
         capital.

         The Company also notes that Canadian GAAP has guiding financial
         statement concepts to be considered when preparing financial statements
         and these principles are described in CICA 1000. Firstly, CICA 1000
         discusses the need for financial statements to be comparable between
         periods and between users. The Company believes the presentation of
         this sub-total assists in achieving this concept. The sub-total
         presented, as well as the total for operating activities, are included
         in the consolidated statement of cash flows to provide two reference
         points for comparability, instead of one. This enables the users of our
         financial statements to determine what our cash flow from operations
         are before any further investment in working capital, as well as after
         any investment in working capital. It also enables users of our
         financial statements to better compare our financial statements
         directly with other Canadian public companies, whose Canadian GAAP
         financial statements include this sub-total. These Canadian public
         companies include, but are not limited to, Suncor Energy Inc.,
         Petro-Canada, Shell Canada Limited, Talisman Energy Inc. and Encana
         Corporation. Four of these five companies are listed on the New York
         Stock Exchange and file periodic and current reports with the
         Commission.

         Secondly, CICA 1000 discusses the need for relevance, in particular to
         predictive value and feedback value. The Company believes that this
         sub-total provides additional information in both of these regards, as
         it again provides two reference points to evaluate cash flow, one
         before and one after changes in non-cash working capital. This enables
         the user of our financial statements to predict and evaluate our cash
         flow before and after any timing of payments or receipts
         considerations, and the user's of our financial statements request this
         information.



         In light of the Staff's comment, the Company would be willing in future
         US GAAP reconciliation notes to its annual financial statements to
         disclose that the presentation of cash flow from operations or cash
         flow from operating activities before changes in non-cash working
         capital does not comply with the requirements under US GAAP.

The Company hereby acknowledges that:

     o        the Company is responsible for the adequacy and accuracy of the
              disclosure in its filings, including the Form 40-F;

     o        Staff comments or changes to disclosure in response to Staff
              comments do not foreclose the Commission from taking any action
              with respect to the Company's filings, including the Form 40-F;
              and

     o        the Company may not assert Staff comments as a defense in any
              proceeding initiated by the Commission or any person under the
              federal securities laws of the United States.



If you have any questions concerning the above responses, please do not hesitate

Yours truly,
