As of today, April 1, fully vaccinated travellers entering Canada will no longer be required to provide a pre-entry COVID-19 test. Fully vaccinated travellers no longer need a molecular COVID-19 test (such as a PCR test) or an antigen test to get into Canada by land, air or water. While you no longer need a COVID-19 test, anyone exhibiting symptoms will still not be allowed to cross into Canada. Anyone entering Canada, including fully vaccinated travellers, must complete a questionnaire on the ArriveCAN app or on the government's website within 72 hours before entering Canada. A border services officer will tell you if you have been selected, and this includes those who are fully vaccinated.
