I would just say, prior to asking a question, that I have visited the north a couple of times and have had the good fortune of visiting the Northwest Territories and places like Inuvik and Fort McPherson and others. I was always struck by the challenges that people face there in building residential homes, and these kinds of things. I visited some friends who live in a very nice home in Inuvik who talked about the challenges of constructing, including permafrost challenges, of course, in the foundation, and the cost of doing that. I think that was a very straightforward home of maybe 2,000 square feet or less, which cost them somewhere in the area of three-quarters of a million dollars to build in the north.
When I listened to Mr. Wong talk about the dependence on diesel and old technology and that kind of thing, that's obviously a way to improve the efficiency. But to improve efficiency in residential homes in the north, I'm not sure what the answer would be. That's why I just raise that.
Mr. Fournier, you referred to some of the challenges. I'd like you to just comment on what might be most practical and affordable.
