That's a good question. Actually, today Canada exports more from its refineries than it consumes, so we are already net exporters. A little over 400,000 barrels a day of exported product leaves Canada and goes to, predominantly, the United States in gasoline and diesel. Much of that comes from eastern Canadian refineries.
There are also some imports that come in, so there is an active trade, mostly in central Ontario and Quebec, between Canada and the United States, but in net terms, more leaves than comes into Canada.
