One comment I would have is that most cities.... I only know two, actually, that are allowed to adopt their own energy codes, codes that are not provincial. It's the City of Vancouver, because of the Vancouver charter, and I think the City of Toronto. All other municipalities have to abide by the provincial code to increase energy efficiencies within the buildings in their jurisdiction. I know that many cities would like to have better energy codes, but simply because of how the provincial and the federal codes work, they're not allowed to.
That's why the City of Vancouver has the best energy code in the country: they have the Vancouver charter, which allows them to have ASHRAE 90.1-2007, I believe, which is a high-level energy code for buildings that are being built within the city. That's an opportunity, I think, because we need to raise codes. If you have a level playing field, it's an opportunity to bring all buildings up to a high level of performance. It's not the only solution, but it's certainly one of them.
