Canada is easing COVID-related restrictions for truckers entering the country, but only for drivers domiciled in that country and not those from the U.S.
"Effective January 15, 2022, all travelers entering Canada, including truck drivers, must use ArriveCAN to provide mandatory travel information, including proof of vaccination. Submission of mandatory travel information can be done up to 72 hours before arriving in Canada. ArriveCAN is available as a free mobile app and can also be accessed via a web-based version at Canada.ca/ArriveCAN. Exempt travelers, such as truck drivers, can also save time by creating a reusable receipt in ArriveCAN. This allows them to submit their mandatory information once and create a single receipt that can be used each time they cross the border."
