You've got loads of hydroelectricity in Québec, that's fairly cheap. In Europe most of the electricity was (and still is) generated with fossil fuel so if you are going to heat a place, you might as well use the gas directly, that's more efficient.

There are a few special cases though: if you go in southern Europe, especially in Greek islands, you will find a lot of solar water heating. And France has a higher than average electric heating due to its nuclear grid.
