I'm not sure if anything is actually in place now. I am very well aware—as probably all of you are as well—of Alberta's intent to submit a regulatory framework that would be an intensity-based or -driven system, so we'll have to see exactly how that comes out.
As far as integration with the American market today is concerned, I think that's a very relevant point. The Canadian market in and of itself, as an isolated market, could only operate for so long; over the years, there would be insufficient liquidity for the Canadian market to be a truly effective, sustainable carbon market. So yes, we do have to be very aware of what the U.S. is developing, but notwithstanding that, if we have certain priorities that we think need to be addressed from a Canadian perspective, then we need to communicate those clearly, quickly, and urgently to our relevant American counterparts.
