Yes, it's interdepartmental, but it's also an inter-jurisdictional issue, because we have tended to put to the level of Canada-wide standards some of the most difficult and intractable issues, such as the smog-forming air pollutants, and we need to do a better job of controlling them.
I guess I would respond just to point out that you've identified one of the key problems, and that the regulatory responses need to be addressed partially in that framework as well.
