I think you'll find that part of that is already being done through the Canada Mortgage and Housing Corporation. They've taken that on. They're looking at various methodologies on how they could do that. Of course, the difficulties you run into are that the federal government has only so much to do with the regulatory part, and it is a provincial responsibility. So somewhere along the way we have to have a tighter fit with the provinces on how that's going to work out.
But to get back to your first question, there is a great deal that has to be done on indoor air quality. It hasn't really had a home before. I'm looking forward to it now finding a home, and I think a great amount of work can be done there.
