I disagree, there's really no politics on immigration. It's evident from the recent official word about the public support for immigration. As I explained a few posts back, inviting and processing outland FSWs had been a risk for IRCC because those apps don't get finalized before 8-9 months at the earliest. Imagine inviting FSWs from Jan to June 2021. This would mean, at best, IRCC would have finalized the apps from Jan to March before 2021 had ended and miss 2021 target by a large margin. See I'm not even talking about CoPR and travel restrictions because it was never really relevant. So what IRCC did was invite and prioritize CEC because they had the ability to finalize those apps within 6 months so almost "all" CEC ITAs turned into 2021 PRs which helped this year's target.
But now it's different close to the end of the year. CEC won't be fast enough after September, most CEC apps cannot be finalized in less than 3 months so IRCCs only option (especially when there's exemptions for CoPRs now) is to quickly finalize "near-the-end" FSW apps from 2020 and 2021, which are either all passed, or all passed except security, and let them come to Canada before the year ends. This is the only way they can meet 2021 target. Also, FSW will have to continue after September because why invite low CRS CECs if you know you can't finalize their apps before 2021 ends? IRCC will go back to FSW soon to prepare for 2022 target while maintaining a high CRS cutoff.
