On November 10, 2016, the Government of Canada implemented a system to electronically verify that travellers have the appropriate travel documents to fly to, or transit through Canada before boarding their flight. As a result, Canadian citizens, including dual citizens, need to present a valid Canadian passport, temporary passport, or emergency travel document to board their flight to Canada.
