Electric heating also works great basically everywhere else, too. Actually climate has very little to do with it in most cases and if there’s any non-manipulative reason(gas companies are really bad for this) it’s to do with what infrastructure makes the most sense.

In places like Québec we have electric heating because hydro makes electricity pretty cheap. Up north in Nunavut they will often have big tanks on the property and a truck will come by to refill them.
