We've been in close contact with our counterparts in the U.S., and there is definitely a view, industry association to industry association, that it's important--the U.S. is our largest trading partner--to have a comprehensive North American approach. I know they've said that the current government is engaged in a clean energy dialogue in terms of looking at cross-border cooperation to try to address those issues, so I think there's definitely been some movement in terms of trying to look at a North American strategy.
