I participated personally in the development of the POPs treaty, and industry certainly had no objections to any of those chemicals being listed in the POPs treaty. As I said in my brief, there's an element of practicality in the POPs treaty. You don't have to worry about trace contaminants of things that are being emitted in levels that you should worry about, but don't worry about it when they're in irrelevant trace contaminants. I think that's an element of practicality that everybody agreed to in the POPs treaty that isn't in CEPA and should be built in.
I don't know if that's one of the barriers standing in the way of using those provisions or not. That's a question you'd have to ask Environment Canada. One of the reasons isn't because industry has been fighting against this. We did not push against this in the POPs treaty at all, and it's not here.
