PR card expires not PR. Do you meet your RO? How long have you been out of Canada and have you visited your home country? By travel document I assume you mean RTD.
Yes only the date on the card is expired.
I just left canada from 3 weeks I spent 973 days in last 5 years .
I didn’t meet RO ( and sorry but can I ask what it is stand for? ) , I applied online 1 week before I left via my immigration consultant.
( by the way I applied 2 years ago for citizenship and I received the letter from that time but till now my application is in process )
I didn’t visit my home country I have family visit visa as they are residents in another country and I left for medical reasons to be with them for recovery depending on my doctors advice in canada .
I m refugee so IDK. if my travel document means (RTD)
