Without ties to Canada (especially without a SIN), it's hard to see why you would have to pay any taxes. Ties would consist of real property, cash/investment accounts, etc. Revenue Canada used to have 1-800 numbers to ask questions (even worked from the US).lemmistay said:Suppose you land in Canada, get the PR card and return to the USA without establishing a home or apartment in Canada, without getting a SIN card and without getting provincial health care. Do you still have to pay taxes on your USA income?
