Well, I think those issues are being considered. I think they're being considered more from a domestic perspective than a trade perspective at this point because of some of the factors that you're talking about.
Obviously, government policy in this area is going to be.... We've been hearing quite a bit from both the EU and the U.S. on these issues, but I think all of those factors are being taken into account, including the potential impact on health care costs and the potential impact on provincial governments, which have been raising the issue with us as well.
So there's an active domestic debate going on at the moment, but I wouldn't say that it has shown itself in the trade negotiations to this point.
