You have to realize there are only a few provinces, a few jurisdictions in this country that have an energy requirement, if that's what we're talking about here. The national building code would apply. The provinces adopt the safety aspects of the national building code, but there hasn't been the same adoption of energy codes. Ontario has one. Vancouver has one. The rest of the province of British Columbia has a separate code from Vancouver's. Quebec has one, an old one, but nonetheless an energy efficiency requirement.
None of the other provinces have energy efficiency requirements for their buildings, if you're not aware of that.
