In some of our comments, we may ask you to provide us with information so we may better understand your disclosure. After reviewing this information, we may raise additional comments. 	Please understand that the purpose of our review process is to assist you in your compliance with the applicable disclosure requirements and to enhance the overall disclosure in your filing. We look forward to working with you in these respects. We welcome any questions you may have about our comments or any other aspect of our review.

Notes to Consolidated Financial Statements, page 59 Note 2 - Significant Accounting Policies, page 60 Foreign Currency Translation, page 61 2. We note your disclosure that your non-monetary assets are translated using historical rates of exchange. Since your translation methodology does not appear to be permitted under US GAAP, tell us why you have not included the difference arising from your foreign currency translation as a US GAAP difference. Note 4 - Border Biofuels Ltd., page 68 3. We note your presentation of the results of your discontinued operations. Please explain to us the circumstances surrounding your recognition of a gain on the disposal of Border Biofuels Ltd. (BBL) and provide us the details of the calculation.

We note your disclosure related to the convertible debenture you entered into in December 2004. Please expand your disclosure to indicate that the conversion terms require you to issue additional warrants upon conversion and specify the number or rate at which you will issue these additional warrants. 5. Also, we note that the fair value of the 500,000 warrants issued in connection with the CDN $1,000,000 convertible debenture was approximately CDN $1.05 per warrant which differed from the fair value of CDN $.22 of the 312,500 warrants issued in connection with the CDN $1,000,000 long-term loan. Please explain the basis for this difference in fair value. Note 11 - Share Capital, page 74 [c] - Shares to be issued, page 74 6. Please expand your discussion of each escrow agreement to include the following: * The transaction, service or agreement giving rise to the original escrow agreement and the date; * The conditions for release of the shares escrowed and the length of each escrow agreement; * Your accounting policy for escrowed shares including their impact on earnings per share. Note 17 - Government Assistance, page 88 [a] Technology Partnerships Canada, page 88 7.	We note your disclosure related to your contribution agreement with TPC.

Note 20 - Reconciliation of Generally Accepted Accounting Principles, page 91 8. We note that for US GAAP purposes, you account for stock appreciation rights and performance based stock options as variable compensation under APB 25 and that compensation related to variable plans is recorded in your US GAAP reconciliation when it becomes probable that the award will be earned. We advise you that variable equity awards should be expensed over the period or periods the employee performs the related services and adjusted in subsequent periods up to the measurement date for changes, either increases or decreases, in the quoted market value of the shares of the employer`s stock covered by the grant but shall not be adjusted below zero. Therefore, it appears that you should revise your US GAAP net income for all periods presented to properly account for your variable plans or tell us why a revision is unnecessary. Refer to paragraphs 3 and 4 of FIN 28. 9. Please revise your US GAAP reconciliation to disclose the following: * Balance sheet differences from Canadian GAAP; * Present the tax effects of adjustments to Canadian GAAP. * * * * * As appropriate, please amend your filings and respond to these comments within 10 business days or tell us when you will provide us with a response.
