If you can read in french .. is a really awful situation...
It's totally messy !
Saying that validating your PR and come to live sounds now to be "Non essential trip" (Unless your sponsor already live in Canada)
Those ppl got accepted by the airline to board , SERIOUS ADVICE for new ppl getting PPR and COPR... i would validate twice with IRCC and CBSA before going. (Requesting a proof of acceptation and exemption at the border)
Such a fail ! Even if you have a PCR test negative, a quarantaine plan and all the correct papers.
So to resume
Validate PR and Entry to Canada
-> PCR TEST Negative (72 hours)
-> COPR letter
-> Visa (IF required)
-> CSQ (if Quebec)
-> Quarantaine plan
-> Status
SPR - Canadian AND Live in Canada OR Already PR in Canada) ->
Yes granted PA
SPR - NEW PR (INTL) ->
NO (Both are facing deportation)
