On October 6, 2021, the Government of Canada introduced new vaccination requirements for air, rail, and marine travellers to limit the risk of spreading COVID-19. Starting October 30, 2021, all travellers will be required to be fully vaccinated in order to travel.

The Government established a short transition period that allows individuals to travel with a valid COVID-19 molecular test taken within 72 hours of travel. Mandatory vaccination requirements will be in place from December 1, 2021, since the transition period will end on November 30.
