he will need a PRTD: https://www.canada.ca/en/immigration-refugees-citizenship/services/application/application-forms-guides/application-permanent-resident-travel-document.htmlHis case is different he is inland and they sent a letter to him stating that it has come to an end and everything is done etc and basically everything has already been approved. The appointment is set to receive PR that's pretty much it. So does anyone know ??
he can call CIC to get proper direction.
i have also read from a post in 2014 that CIC advised to show COPR when returning to Canada after the trip and they can look up in the system. he will need to show the airlines a valid document, if he still has a valid work permit (i.e. its not crossed out) he can show that to the airline so they let him board.
