If we already approved your permanent resident application
Permanent residence applications approved on or before March 18, 2020
If your application was approved on or before March 18, 2020, but you haven’t travelled to Canada yet, you’re exempt from the travel restriction measures.
Landing appointments will be held by telephone, if possible
We cancelled all in-person permanent resident landing appointments until further notice. All landing appointments will be done by telephone whenever possible. Otherwise, we’ll reschedule them for later.
We’ll contact you by email to let you know when your phone appointment will be. Use the
Web form if you need to update your contact information.
