Depends what part of Canada you go to. But be advised - the one-day record for snowfall in Alberta was on (IIRC) June 29th one year.
It is weird - a co-worker and I once flew to New Orleans from Calgary in December. It was 30 degrees below zero Celsius (approx. -22 Fahrenheit) when we left Calgary. The temperature in New Orleans hit 31 degrees Fahrenheit the night we arrived, and they declared a state of emergency.
But I vividly remember, standing outside the hotel unloading our luggage from the taxicab, how bitterly cold it felt. Being on the ocean makes an astonishing difference. <img src="images/graemlins/shocked.gif" alt="" />
But we experience it too. My (ex) sister-in-law went to Inuvik, on the Arctic ocean (my brother was working as one of the town doctors there) and they went on a camping trip. She got up in the morning and was colder than she'd ever been in her life; she had her tuque jammed down over her ears, her parka hood pulled up, her parka zipped *and* buttoned, big woolen mittens - then her Eskimo guide walked out wearing a cotton flannel shirt and said, "It's a bit nippy this morning." <img src="images/graemlins/cool.gif" alt="" />
