To answer your last question first, yes, the capacity is more than sufficient to meet all of Canada's needs. Our plants are under capacity, particularly in the west.
We export a very limited amount. Our major export market would be the U.S., but as I mentioned, we're constrained by a 10,000-tonne quota. We exported a little more last year because of that refinery explosion, and during Hurricane Katrina when they had a shortage. Other markets are very sporadic: a little bit in the Caribbean and under a couple of FTAs, perhaps; a little bit to Israel once, for a small quantity. But most of the major markets are protected. This comes back to why we invest so much time on the trade agenda; it's the only thing that's going to pry those markets open.
So it's a matter of trade barriers that restrict us.
