It's not as if we've imposed any costs anywhere. I think there's some validity in looking at that as a concern moving forward. On what the CLC has said around the climate change issue, as far as setting emission targets for large final emitters, and so on, there should be some consideration given to competitive factors in terms of the costs.
For example, if we're building a new refinery in Saint John, New Brunswick, and the U.S. doesn't match the cost of carbon that goes in, that kind of investment would go south of the border. But I think that speaks to the importance of bringing the U.S. into the Kyoto process as well.
