This is an official response to a news editor called Shelby Thevenot. IRCC says they've contacted all pre Marc 18 2020 expired COPR holders. Furthermore they say, they'll contact the rest of COPR holders (the ones who got it after March 18 2020) until the end of October 2021.
I want to believe incompetent IRCC hasn't allocated all of its FSW officers for this because if they did, there will be no new COPRs before November, and people who've been waiting for 2 years with approved files will continue waiting.
I'm not saying they did it, I'm just speculating like everyone else so take this response however you like.
