I am a u.s citizen and holding a Canadian pr card. I landed in November 08 and I don't even know how long I have been stayed in Canada, because I travel back and forth between u.s and Canada 4 times a yr because of my parents every time i came back to canada I stayed for two or three wks since I landed. I am still visiting my parents in the the state right now and my pr card will be expired in November 13. My question is what is my chances are keeping my canadian residency statue? For the last two yrs I have been walking across the broader without any problems.
