April 8, 2021 UPDATE:
Our School is a DLI ‘Designated Learning Institution’. International students with visas have no problem returning to Canada. We encourage all students to return ASAP so that they can complete their 14-day quarantine in due time, and return to proper school infrastructure.
Many students have entered Canada without any issue however there have been a couple of cases where the airlines (wrongly) refused to allow them on their flight. They are absolutely in the wrong and it’s important to be firm with them (and of course nice). Point them to the Canadian government website posted here https://www.canada.ca/en/immigration-refugees-citizenship/services/coronavirus-covid19/students/approved-dli.html
We’ve checked this morning, again, with government officials and they’ve confirmed this. Additionally, many airports have something called a Canada Helpdesk. Parents who stood their grounds, demanding the airline double-check with Canada Immigration, have ultimately been allowed to board the plane and entered successfully.
