Being it's a world market, everyone in the world that's producing oil has the same world price. The differentials between light and heavy certainly have an effect. The ability to get our products to market is a challenge. It's something I think was important at $80, $90, $100 a barrel. It's an imperative that we have these type of efficiencies at $50 a barrel.
In Canada from Quebec and eastern Canada they import 60% of their oil from offshore—Angola, Azerbaijan, Norway. I think if we're looking at Canada, Canadians should have access to Canadian oil.
