Any place that regularly gets below -40C (in other words, places colder than Edmonton) has block heater plugs in parking spots. You can hook your EV up to the block heater plug and it'll keep your battery warm. In the summer that plug will also charge your car. In the winter, it just keeps the battery warm. Which incidentally helps range because a warm battery lasts a lot longer than a cold one. If you're not plugged in, your EV should be using its stored energy to keep the battery alive, which it can do for several days.
