So I found out about this website: http://www.albertaev.ca/faqs/ (Alberta Electric Vehicle Association) and there's some interesting stuff incl:
How do EV's handle winter?
Incredibly well! Most EVs have a number of advantages over other vehicles.
There is never a fear that they won’t turn start, even on the coldest days. As there is no oil, there is no worry that it becomes too cold and thick, nor is there a concern about a 12V battery getting too weak, failing to turn the engine over, or the starter motor failing.
No more need to stand outside on a frigid morning refueling the vehicle at a gas station! It takes just a second to plug an EV in at the end of the day, and it will be full and ready to go well before you are the next day!
Perhaps the best part of winter EV ownership is that they heat up super fast! Not relying on the waste heat of the gasoline engine, most EVs instead use resistance heating, which generates heat nearly instantly. Yes this does consume a bit of battery, but even with any range impact, almost all EVs easily handle the Canadian average daily driving instance. Additionally, as next generation EVs are coming to market, with their larger batteries and thus increased range, the impact of winter range loss is quickly becoming a moot point even for drivers that greatly exceed daily driving averages.
