I missed the 180 days for my PGWP. Is there anything I can do?

The 180 days is not counted from your graduation ceremony, and that is where most people lose it without realising.
It runs from the earliest of three dates: the day your final marks were issued, the day you received formal written notification that you completed the programme, or the day your credential was issued. Whichever of those came first is the one that started your clock, and for most people that is the marks, months before the convocation they were thinking of.
The requirement itself is written as a must. IRCC's officer instructions, last updated 11 December 2025, state that the application must be received within 180 days of obtaining that written confirmation, and the page sets out no general discretion to accept a late one. The only exception is that it applies to students who graduated outside Canada under the special measures.
What people miss when the date has passed is that two separate questions are involved. Whether a post-graduation work permit can be issued is one. Whether you can lawfully remain in Canada is a different application with a different test, and it does not rise and fall with the permit. Losing one does not automatically decide the other.
If you are past the date, the useful thing is to stop asking whether the permit can still be saved and start asking what your status options are, because those are the ones with something live in them.

This is general information rather than legal advice, and it reflects the page as it stood on the date above.
