There's a guy on YouTube who lives in Saskatchewan and drives a Tesla. I asked him how (Canadian) cold weather affected battery life. He said he suffers a 40% loss of range (500 vs 300 km).
This jives with some numbers I've heard anecdotally here in Colorado. 300 miles drops to 180-200 miles in "real" cold weather
