Post Graduation Work Permit and Temporary Resident Visa
Case 1: Your TRV/eTA is still valid
If your current TRV (Entry Visa) says "Student" and is still valid, you will not need a new TRV if you are changing your status to "Worker".
Your TRV is valid regardless of whether it was issued to you as a student or worker.
You can enter Canada with a TRV – “student” with a work permit.
Case 2: Your TRV/eTA has expired
If you apply for your PGWP from outside of Canada:
You will be automatically issued a new TRV or eTA by the officer at the same time as the documents you need for your entry to Canada as a worker (see Immigration Canada website).
You do not need to complete a separate application or pay additional fees.
If you apply for your PGWP from inside of Canada:
You will NOT be issued a TRV or an eTA automatically.
You must apply separately for your TRV or eTA if they are expired.
