I am close to getting US GC. My landing papers for canada are expiring in march. Due to bad USeconomy,as a worst-case backup, I have decided to land in canada and come back to USA immediately. But if I dont go back to canada after that and return the canadian GC within 183 days, do I end up paying canadian tax for this year OR since I stayed for less than 183 days, am I not subjected to canadian tax?
