COVID testing isn’t required for vaccinated travelers after April 1. But you will need this

While vaccinated travelers entering Canada will no longer have to get tested for COVID-19 before arriving, all travelers must provide mandatory travel information before getting to the border.

Subject to limited exceptions, all travelers must use the ArriveCAN app or website to submit their travel information to Canadian officials before coming to the border crossing. The app/website will have users upload a variety of documents, including a photo of their vaccination card. The app is free and available on the Apple App store and Google Play. The app won’t let a traveler submit information about their trip until 72 hours before they arrive at the border. So for those who want to go into Canada on April 1, the time to start submitting information is March 28 or later.

When you arrive at the border, Canadian border agents will ask to see an ArriveCAN receipt, which can be in the form of a printout or on your phone screen.
