The value of a refinery is driven by its location. Refineries that are close to consumption generate good returns.
The challenge in Alberta, for example, is that we are so remote from the consumer in delivering the product. We export the crude to the U.S. rather than finished products because they are more efficient and it's more cost effective to do it there. There are more refineries in eastern Canada because they are close to the consumer, and that's when you have a competitive advantage.
