yyz2hkg: are you from Redflagdeals? The name sounds familiar!
I'm just guessing that you were born in Canada, so were your parents "settled" there when you were born? If no, then you will be a Chinese citizen and can get a HKSAR passport.
I had a friend that was born in Canada and then he went back to HK and they thought he wasn't a Chinese citizen, and had to go through a bunch of stuff to get it re-established. (He actually was a Chinese citizen because his parents were on student permits when he was born)
