If you’re outside Canada and don’t have a valid PR card, you need a permanent resident travel document (PRTD) to return to Canada. You can only apply for a PRTD from outside Canada. If you try to return to Canada without a PR card or PRTD, you may not be able to take your flight, train, bus or boat to Canada.Most PR cards are valid for five years, but some are only valid for one year. The expiry date is printed on the card. When your PR card expires, you can’t use it as a travel document. If your PR card will expire within six months, you should apply to renew your card. You need to be in Canada. If you’re re-entering Canada by commercial vehicle and have an expired PR card, get your PRTD to re-enter Canada.
