yes I got it by email today and I'm currently in Canada. I found some information on the IRCC website :
If we already approved your permanent resident application
If you’re already living in Canada: in-person landing appointments cancelled
We cancelled all in-person permanent resident landing appointments at our offices in Canada until further notice.
If you got your CoPR, but haven’t landed
If we sent you a CoPR, but you haven’t been able to go to one of our offices in Canada to validate it, we’ll contact you to tell you what to do.
You should not travel to a port of entry to validate your CoPR. This is not considered essential travel and you won’t be able to validate it this way.
Due to COVID-19, we have a new process to confirm permanent resident status. We don’t need a CoPR for this new process if you applied from within Canada.
I don't understand the last sentence exactly but I assume that they will contact me or they will find other way to do the landing (Flagpole or IRCC office interview which is closed now). And also, according to my CoPR letter, they told me to send a copy of CoPR and 2 photos for PR card to Winnipeg IRCC landing photo office (I'm not sure they are open but the letter say they will do it but will take longer). So I guess I don't need to do the flagpole or interview.
