Okay. So there is an extra cost to it.
Mr. Chair, I also want to refer to Mr. Cane's comments earlier about the Province of Ontario looking to basically regulate common sense by saying that when you open something, you have to put something better in. I want to raise the point that if you make a law such as that, what will end up happening is that people will say that if they rip off a wall, they're going to have to fix more than just the one problem that's in the wall—a leak or whatnot. People may either choose not to do it or they may choose to do it illegally without proper permits. I think sometimes, Mr. Chair, we have to look at these things and ask whether we are actually creating disincentives for energy efficiency.
How much more time do I have, Mr. Chair?
