You don't dress for heat. You UNdress for heat. I was miserable living in the South (US) until I figured that one out. I still don't like it much when the temps are in the mid 90s F, and the humidity is above 75 percent, but I'm not anywhere as miserable as I thought I would be in this climate. And don't forget... Canada as coastlines, and it does get hurricanes from time to time.
