IRCC just announced that if an International Student who already holds a study permit or was approved for a study permit on or before March 18, 2020, is exempt from travel restrictions. That being said, if anyone who is travelling by air will still need to pass a health check conducted by their respective airlines prior to boarding their flight. Any traveller who shows symptoms of COVID-19 will not be permitted entry to Canada. Isolation for 14 days upon arrival to Canada is mandatory.
A students’ eligibility for Post-Graduation Work Permit (PGWP) will not be affected if their in-class courses are offered in an online-only format because of the COVID-19 pandemic. This includes an International student who already holds a current valid study permit or had been approved for a study permit for a program starting in May or June but is unable to travel to Canada at this point in time due to the travel restrictions in place. An International student in this given situation has the option to begin their classes while outside of Canada and may complete up to 50% of their program while outside Canada if they are unable to travel to Canada sooner.
