Again, each application is handled differently. I was answering to the part where you were talking about single applicant vs family application.
Just trying to say, all applications are handled on first come first serve basis. So until someone worked on a previous application, nobody will move to the next one.
HCCP applications are handled by CPC Edmonton and its a newer program. IRCC already has updated in April, 2021 that they have approved PR for 2000 Applications till Year 2020. All applications, received in year 2020 after March are lagging behind because of the closure in Alberta. It was hit pretty badly, and still going on.
Those who are not getting any update after Permanent AOR (2019 and 2020 applicants) should apply for GCMS notes and check themselves, where exactly is the application stuck.
