It's an interesting question. CELA, my organization, is doing an analysis of the bilateral agreements, not just Canada's but those of a number of countries, to figure out what are the differences in terms of protecting the right of countries to do their own environmental regulation, free from investor-state challenges. We haven't completed that, so I don't know if I want to say it's clear that Canada does and the others don't.
