Well, Mr. Chairman, I can only speak on behalf of Cenovus. When we were considering this investment, we looked at the economics of refining and upgrading in Alberta and at existing refineries in the United States, and we found that the economics were better there.
We also found that there is an environmental benefit to refining only once. Upgrading in Canada, moving the product to the United States, and then refining there means you have to heat it twice. There's actually an environmental benefit in not doing that.
I should also point out the deal we made with our partners on the refineries. We own 50% of two U.S. refineries with ConocoPhillips, and Conoco operates them. Conoco then made a corollary investment in our Foster Creek and Christina Lake projects, which enabled us to expand those projects and provide more jobs and economic benefits for Canadians.
