Let me explain about my landing experience:
I traveled from Denver to Sweetgrass-Coutts border on 07/26/2020 (Sunday). At entry point the officer asked me the reason for entering Canada for which I told him that I want to activate my PR and return back immediately but planning to permanently return back soon. He gave yellow slip and directed me to the CBSA office. The officer there asked me the reason and was extremely unhappy with my decision to travel during the pandemic. He told me that there was no need to travel for immigration which is a non- essential purpose. He made me wait for 1 hr and again called me and told that he doesn’t want to issue PR and asked me to return back. I told him my COPR is expiring in 2 months but he countered me that all expiring COPRs will be extended. Then I told him that there are no clear guidelines for extension process and the duration it will take and I am planning to return back for settlement in 3 months. He again asked me to wait for 30 minutes and in the meanwhile did background check on me and finally called me with signed COPR and said my PR is activated from today. I literally felt like a miracle given the situation.
So, it depends entirely on the CBSA officer’s discretion whether to entertain our request during these times.
While returning back to US, they found my visa was expired, asked for my i-797 and directed me to DHS office. They made me wait for 1 hour and then said they cannot allow me to enter US since my visa was expired and asked me to return back Canada and get stamped visa. It seems they were not aware of AVR process, so i explained them about this process. But they were adamant on refusing entry and said since my expired visa with old employer and i797 is with new employer, AVR process is not valid in my case. Some how they again asked me to wait, this time 2 hours and finally called me and said I can enter US.
To conclude, I took a chance and it paid off. I am not sure whether you can follow the same path as it depends on the border officers on both sides.
