Because your comment suggests that heat pumps can't work in Canada. It's like an American dismissing heat pumps because Alaska is part of the US. For at least 70% (if not more like 90%) of Canadians, heat pumps work just fine. Obviously, if you are in the part of Canada that gets consistently below -40 degrees, don't get a heat pump.
Also, I'm not from Toronto or Canadian so I'm not sure all that talk about elitism applies to me. I'm from a small city in the US where I experience weather similar to most Canadians.
