According to IRCC's last budget earlier this year, it looked like the plan was to clear the last TR2PR applications in 2023, or at least the numbers that had been processed in 2021 and the remaining budgeted for 2022 & 2023 seemed to add up to the approximate 90,000+ applications. BUT, then they extended the validity of OWP under TR2PR to a maximum of Dec 31, 2024, leading many to believe that IRCC might be planning to still be processing applications into 2024. Perhaps a clearer answer will be in the new budget. It's supposed to be released by November 2022. We might have a better indication of their plans soon.
