I note that the relevant phrase says the Governor in Council “may”, which means the Governor in Council isn't obliged to. It isn't a “should” or a “shall” or any of that stuff. So that's one issue.
I don't think there's probably a difficulty with the second part, which is (b) by adding after line 14:
Despite paragraph...each province may take any measure that it considers appropriate to limit greenhouse gas emissions.”
I have three concerns. One is whether in fact there is the suggestion that the federal government could impose an overall greenhouse gas emissions target on a province. That's one issue: do we have the power to do that? I'd be interested, actually, in hearing from a legal point of view whether we have a challenge here.
Secondly, I'm a bit concerned about what it might mean to our international trade obligations, and I'm thinking under NAFTA. It's one thing to take a sectoral approach and say that all cement plants across Canada are subject to the same emissions cap, for example. It would be quite different, it seems to me, under NAFTA to say that cement plants in Quebec are subject to a lesser greenhouse gas emissions cap than ones in Ontario and Prince Edward Island. So my second point is on international trade.
My third point, which is less a legal question, is whether this in some way undermines the possibility of having a national market for emissions trading when you have the same industry in different provinces with different standards.
Those are three questions I raise. My fourth question is, if there's any ambiguity, particularly on trade or the federal power, is there any danger, given that we put the word “could” in, that this whole bill could go down because we're offside on either the federal power issue or the trade issue?
That's really a technical question, and I'm wondering whether our legal counsel can give us some response to this.
