When I think of Canada, I think of frostbite...though I'm hoping my tendency toward exaggeration in indeed a tendency when it comes to weather in Toronto. Moving there to pursue a Master's and allergic to cold. Can someone please offer me a glimmer of hope or at least give me fair warning when it comes to what clothes to pack.
You'll definitely need to pack a warm jacket and warm shoes, and on top of that, raingear is essential. It rains pretty consistently throughout the year, so galoshes during winter and a lightweight waterproof jacket during summer are items that can make the difference between a miserable mood and good one.
Otherwise, take solace in the fact that most Canadian houses and indoor areas are well-insulated. Central heating is a norm, so once you come in out of the cold, you can pretty mush strip down to your birthday suit - depending on your location and how much you'd like to pay for monthly electricity.
