Canada’s entry requirements are changing
Permanent residents of Canada must carry and present their valid permanent resident (PR) card or permanent resident travel document when boarding a flight to Canada, or travelling to Canada on any other commercial carrier. If you do not carry your PR card or permanent resident travel document, you may not be able to board your flight, train, bus, or boat to Canada.
It is your responsibility to ensure that your PR card is still valid when you return from travel outside Canada, and to apply for a new PR card when your current card expires.
It depends on whether you are inside or outside Canada. Either way, you have to tell us what happened so we can prevent your card from being used by someone else.
Follow the instructions in the “Replace a lost, stolen or destroyed PR card” section on the page to apply for a PR card.
