Are you inside Canada now? If so, apply to extend your stay as a visitor. (not visitor visa which will allow you to enter Canada as a visitor)
I’m in Canada working now. I’m exploring my options early in case if my employer won’t support my closed work permit before my pwgp expires in December.
I already have a visitor visa to enter and it’s tied to my pgwp expiry date.
I applied for non-ee PR in March. There’s small chance that it will get approved before December 17.
