I certainly would echo Mr. MacLean's remark that because we're operating in the context of a North American fuels market, of which Canada comprises approximately 10%, we're ultimately price takers with respect to the price of wholesale fuels.
The rise in fuel prices paid by Canadians this past few months has clearly been driven by the increase in crude prices. That has had an impact on refiners, in that refining margins have decreased significantly from where they have been in the past year, as demand in the U.S. in particular has begun to ease. Retail margins have been consistent for some time. So as far as speculation in crude markets goes, I would echo Mr. MacLean's remarks.
