People coming
directly from the USA would be allowed. So you have to cross land border or have a flight straight from USA. I confirmed this with CBSA.
How did you confirm this news?. Did you email or call them?.
Please share their number and email so that I could also try reaching them.
Thanks,
If you intend to quarantine, the immigration officer doesn’t care if you return back after you are PR. At the time of landing just present your case that you’re moving to Canada. And then after 14 days you can return back.
There’s also this exception which may be worth trying if you don’t want to wait 14 days.
Exception — leaving Canada
8 A person who must quarantine themselves under section 3 or remain in quarantine at a quarantine facility under section 4 may leave Canada before the expiry of the 14-day quarantine period provided they continue to quarantine themselves until they depart from Canada and provided they depart in a manner consistent with the travel requirements set out in section 2.2.
