Starting in “early” November, nonessential travellers, such as those entering for tourism or to visit family members, will be required to show proof of Covid-19 vaccination to U.S. Customs and Border Protection officers when they cross land borders.
For the past 19 months, only “essential travel” had been allowed across the Canadian and Mexican land borders, but the same restrictions did not apply for air travellers.
Starting in January 2022, all travellers to the U.S. from Canada, including essential workers, will be required to be fully vaccinated.
Details are still to be worked out
As there is yet no standard vaccine passport in Canada, much work needs to be done on this file.
