This is how we dress for the outdoors here. You need a winter jacket, ski pants and winter boots. Mittens, wristwarmers, two scarves, a toque, and a "neck warmer" (which I had to put on her head because her toque didn't cover her forehead lol)
As a result of all that you get a one year old who has a blast outside even in the -15C weather (that's pretty warm for us) and she did NOT want to quit when her mom came to pick her up. :o)
Today it got above freezing even! Very warm! I could get used to that but I'm sure it'll be back to -40 again at least once before spring.
