Here I've seen people from UK, India, Belgium, etc.
My slightly educated guess is that now luck depends more on the medicals validity/expiry date. For example, mine were extended in Feb 2021 till Oct 28th. So I am in the "don't issue COPR" batch until they expire again and IRCC determines if I need another extension or re-medical. So if you have more than 6 months of medicals validity and "all stages passed", you might see your PPR email anytime.
But that's my goddamn optimism. My realistic brain tells me I won't be ever approved due to a combo of my country of citizenship, NOC, family composition, etc. Just not attractive to Canada.
