Finally got the pr confirmation letter today. My experience seems a bit different from most of others. I'm an inland(Vancouver) applicant and got a landing appointment letter saying that landing interview is scheduled on March 16 without PPR/COPR, but of course, the landing interview was cancelled due to covid situation. Since then I've phoned in and also sent webforms to ask about when the landing can be scheduled and only got generic reply from IRCC. Then FINALLY today I received a telephone landing interview call from IRCC(No caller ID) this afternoon and the agent just asked me a few questions (Address/if have committed any crime etc.) and then about one hour later the pr confirmation letter is updated on MYCIC. And in the letter, I'm just asked to send IRCC vancouver office two photos in order to apply for pr card.
Good luck to all of those people here still waiting for their pr mail! Hope you can get yours soon!
