Oh, that's a really interesting question, because Canada is a signatory to the Minamata Convention, as you know, which is tasked with controlling releases of mercury. It's very timely that you mention this. Canada has been involved in reducing mercury emissions through the International Joint Commission, for example, the binational task force that operated some 10 years ago but actually hasn't been doing much since then.
That's been directed toward point-source releases, but the reason that I'm glad you asked that question is that right now there's a very visible discussion about what's happening at Grassy Narrows First Nation, where they have been subject to elevated mercury exposure due to past releases, and it does not seem to have been adequately addressed. We're addressing mercury and releases in a very big-picture way, but here we have a case that we're not acting on, a very immediate and very egregious case in which people are experiencing mercury poisoning.
