We are involved. We're involved in the full value chain of oil and petroleum products in Canada, and to some extent, in the U.S. We are an upstream producer of products. We upgrade that product. We transport it, either through some of our own pipes, or more generally, the pipes that are open to public participation.
We have three refineries in Canada and one in the U.S., as you rightly point out. We participate in the wholesale and retail markets in Canada through our Petro-Canada brand.
We operate right across the value chain. We also trade volumes across that chain, so we're very knowledgeable and participate in all aspects of that value chain, if I can put it that way.
