If you must travel, use the ArriveCan App.
All travellers, (with limited exceptions) whether entering Canada by air or land, are required to provide travel, contact and quarantine information upon and after entry into Canada using the new ArriveCAN mobile app.
This is part of Canada’s efforts to reduce the spread of COVID-19 and prevent importation. This information is crucial to Canada’s response to COVID-19. More information on how to download the app can be found here: https://www.canada.ca/en/public-health/services/diseases/coronavirus-disease-covid-19/arrivecan.html
