Will an unlocked Apple iPhone bought from outside USA, work in Canada? - usa to canada phone card

I'm moving to Canada next month, and have not yet decided what to do with my iPhone, I am all love. I did some Google and found that the iPhone is not officially in Canada, and as I am (University MUN) my iPhone is a show-off will be! Is the phone in Canada with a SIM card?
