I also want to talk a bit about this whole idea of retrofitting that Mr. Fast introduced. Part of it relates to previous study that I'll refer to, in which we heard about heritage. In the area I live in in metro Vancouver, we have communities that are redefining themselves, and it seems to be much easier to landfill buildings than to try to retrofit. That's concerning for somebody who sees value, including environmental value, in retaining the existing housing stock that we have.
I think we've touched on it, but I think we've heard from witnesses in other studies that the existing national building code does not touch on heritage, and I would hope that, moving forward, we'll see something that recognizes the embodied energy that is within existing buildings and how we can do a better job of trying to retain those moving forward.
I don't know if you have any comments.
