What? Maybe in the most northern reaches.. even then "for several weeks" is a stretch.. even Uranium City doesn't hit -40°C every winter!

There is often confusion between wind chill, and actual temps.

But the parent is not inaccurate, for they did not mention "each year". Even 10 minutes North of Ottawa, I saw -42C, real, not just windchill, for a week, about a decade ago.
