Coldest drive I've ever done was Charlottetown to Toronto this past January. It was -16°C leaving Fredericton, and only got colder, bottoming out at -28°C (w/o the windchill because that's fake cold) between Laval and Ottawa. At those temperatures in a S 75D you must range charge to high states of charge just to get 200km range with safety. 2 hours driving = 1 hour of charging. A significant increase in the time required. It sucks.
Therefor IMHO the ideal distance between Superchargers in Canada is closer to 130km. Ideal for skipping every second one in temperatures as low as 0° while not range charging, and spaced close enough that extreme (not just the cold) weather doesn't cause you to range charge.
I have argued differently in my last 2 posts, but I have also never driven highway distances in -16 to -28, so I will defer to your experience.
But in "normal" winter cold, there is no way I would get as little as 200 km. Definitely down between 300 and 350, but...
Your point about "range charging" is, of course, correct. My arguments were only about ability to move that distance. The amount of charging time is also an important consideration.
On my last trip to NYC (and in general) I try to cruise into superchargers with ~20 km range left, and charge only to 1/2 full (to get the most fast charging as possible).
In the summer, that's easy because my car is always conservative when it estimates my range because I drive the speed limit.
Trying something similar in the winter though is a bit more harrowing--watching the estimated range left at arrival tick steadily downward is not for the timid.
