To elaborate on the points by my colleagues, clearly there's that issue of Canada versus U.S., and if we were put in a position where we had to, in essence, either face a carbon tax in the U.S. or buy carbon credits to somehow match up, that has a direct economic consequence for producers here.
Even if Canada and the U.S. more or less move in lockstep, the other factor, frankly, is this growing dominance of China in terms of world steel trade, and that's really a core factor in our industry. If China is not facing obligations such as we are, that trade and investment impact is important to us as well.
