Random story worth mentioning:
A good friend of mine married his wife in Lebanon in 2019 then went back to Canada and started the paperwork for spousal sponsorship. After AOR1, they applied for a TRV and it was granted for a year. They lived together until they asked her to go back to Lebanon and get her PR visa in March 2020. She went there in February, got the PR visa and you know the rest of the story. Border closure. PR visa expired. TRV expired. She had to contact MP's and IRCC countless times until FINALLY, in July, they asked for her passport again. They kept her passport in the embassy for 3 months and a half!!! They finally handed back her passport 2 days ago, and she arrived here this morning.
Something here doesn't make sense. Canada's border closure I don't think kept COPR holders with spouses in Canada out. (Perhaps there was for a short period, don't recall)
