Unless you're well prepared, winter in Toronto can make you wish you'd never been born. January freezes over, with maximum temperatures never topping zeros. The wind-chill factor - lashings from Lake Ontario - can make things feel a whole lot colder. North-south downtown streets become frigid wind tunnels, sending people scurrying like rats into the underground PATH network. In July temperatures can hit the mid-80s for weeks at a time, claustrophobic humidity sapping the very life from your bones…But rug-up or show some skin and you'll be fine!
