If you’re traveling in Canada, soon you’ll need proof of COVID-19 vaccination according to Forbes.

“By the end of October, everyone 12 or older on a plane or train within Canada should be fully vaccinated,” Canadian Prime Minister Justin Trudeau announced in a press conference. He called these measures “some of the strongest in the world.”

“If you’ve done the right thing and gotten vaccinated, you deserve the freedom to be safe from COVID-19, to have your kids safe from COVID and to get back to the things you love,” Trudeau added. According to Canada’s public health agency, as of this week over 80 percent of the nation’s eligible population has been fully vaccinated against COVID-19.
