Starting November 10, 2016, you will need to show proof you are a Canadian citizen to travel to Canada by air.
Travel documents that prove citizenship are:
a valid Canadian passport;
a Canadian temporary passport; or
a Canadian emergency travel document.
If you don’t have a valid travel document that proves your Canadian citizenship at check-in, you may not be able to board your flight.
If this happens to you:
There are no quick fixes to help you get on your flight.
You will need to contact the nearest Government of Canada office abroad to get the appropriate travel document.
