Are they not doing virtual landings now, because of covid?
Before, you had to validate at port of entry or in a Services Canada Office. They are not doing appointments for this reason on Services Canada Offices, as far as I know, and port of entry is most likely for people that applied outside (not inlands) and have a PPR to travel to Canada.
As far as I understand, they can validate your COPR through the new portal page or it comes already validated.
Would this not mean that once you receive your COPR, at least for inlands, you are already a PR?
If that is the case, then you would need to wait for PR card to come back without issues, or apply for PRTD if you are outside.
