If you deferred your intake without first notifying IRCC through a webform, and then received your Passport Request (PPR) for the wrong (original) intake, you can still correct course.
What group members advised:- Raise a webform explaining the deferral, attaching your new LOA that reflects the updated intake.
- Send your passport for stamping — you don't need to wait for a response to the webform before doing this.
- After getting the visa stamped and once in Canada, apply for a study permit extension if the original permit's intake date no longer matches your actual (deferred) start date.
Takeaway: informing IRCC about a deferral late doesn't cancel your visa — pair the webform/new LOA with getting your passport stamped, then handle any date mismatch with a study permit extension once you're in Canada.
