Effective June 20, 2022, the federal government will suspend the requirement that domestic and outbound travellers be fully vaccinated against COVID-19. This means that vaccination against COVID-19 will no longer be a requirement to board a plane or train in Canada.
Canadian citizens and Canadian permanent residents returning from international destinations who do not qualify for the fully vaccinated traveller exemption continue to be required to provide a valid pre-entry test result, remain subject to Day 1 and Day 8 molecular testing, and quarantine for 14 days.
In addition, all travellers entering Canada are required to input their mandatory information in ArriveCAN within 72 hours before their arrival in Canada. Travellers who arrive without completing their ArriveCAN submission may be subject to Day 1, Day 8 molecular testing, quarantine for 14 days, and to fines or other enforcement actions, regardless of their vaccination status.
