I need to enter (and exit to US) Canada for a couple of times driving my US registered car. I do have my PR card.
Will there be any issues ? Should I declare anything at the Border crossing ?
Duration will be around 1 week for each visit
There shouldn't be any problems if you are still a U.S. resident and not a Canadian resident. Meaning you still live in the U.S. and not Canada. It shouldn't matter than you have PR status in Canada.
