I know how cold it is there, my sister in law is visiting my neice in Oakville, Ontario and this morning she sent a photo of the thermometer, -18 at 7.00 a.m. I can't imagine that and apparently it will only get to -12 at midday.
@susiemc Yes! And that's without the windchill being factored in. It's definitely weather for thermals, as @wendyfrost mentioned (I'm wearing mine, Wendy!)
