Everything is finalised for me now. My PR card is winging it's way to me via a friend in Alberta (you need a Canadian address to receive it first).are you waiting for IRCC to tell you get that done? Also, with COVID, these timelines are probably a mute point now. Cricket silence now and waiting since March 2019 when biometrics was done.
The covid farce definitely slowed everything down for everyone across all immigration streams as far as I could tell. I would definitely contact the visa office and find out what's going on. I put my papers in 6 months after you did your biometrics and I've been granted PR now so there's definitely something amiss in your case... Expect them to not like being called or emailed though!
Good luck and keep the fires burning under their feet. Government agencies like to collect their salaries and do as little as possible...
