You can link your PR card application in GCKey. Just search for an application with UCI and other details. You will see update when there is FD and approval. When approved, it will say “we mailed your PR card….”
Not sure if your card was mailed already or not but I'm seeing people on reddit who have called to ask about the pick-up option like last year and some agents have confirmed that for people whose GU1 came after the strike started, they will soon receive notification to pick-up their cards at the local IRCC office. Might be worth calling and asking.
Go to GCKey. Link an application and provide details. Number of applicants 1, cant remember if it asked for that. But UCI and other details should find it
