First of all, I don't know what.... I think you're right. I think air quality in the greater Toronto area is improving. I have heard that. I haven't seen the data on it.
Of course, we do monitor that, and as you may know, we have been working for more than five years now, in partnership with the provinces, on a new air quality management system to improve air quality across the entire country, both through specific airshed management and through a series of federal regulations that are now beginning to be rolled out. The first set of them were put out for public comment by the minister in June.
In terms of the impact of the shutdown of the coal-fired power plants, I honestly don't know. Of course, one would assume it is contributing to improved air quality. Part of the story in that airshed, as I understand it, is of course the transboundary effects. There are transboundary effects. There may be things going on in the U.S. that are also helping to improve....
I don't know if it's yet a trend, but it certainly appears to be positive. We will continue to pursue the implementation of the air quality management system with the provinces in order to keep that going.
