Wear warm clothes in the plane, and have extra blankets for
passengers. Airplanes tend to be drafty, and when the OAT is below 0
deg F, it gets cold in a hurry.

Good point on the clothes. You need to think about what's going to
happen if you have an off airport landing. Treking even a mile when
it's cold out could have consequences you didn't plan for. So boots,
gloves, proper jackets, a hat.. all recommended items for winter
flying in Canada. Yes I know there isn't much room in a Cessna 150.
Stuff the extra things in the back if you have to. Turning into a
popsicle isn't much fun.
