Biometrics given for non-PR purposes (WP) cannot be used for PR and has to be given once again. So far there's no info about using non-PR biometrics for PR due to Covid-19. It doesn't make sense but in this case, we can only say "it is what it is".
Yes I received biometrics last year at an ASC to receive my work permit. Interesting that no one has had this happen to them so far. I was also confused because I know biometrics for work permit generally don't count towards PR. I will try to raise an inquiry to CIC online to see if it's valid.Did you give your Biometrics last year? If you than it's still in ethe system and automatically update it for you. You might wanna call\email CIC and inquiry if you still need to do the Biometrics again!.
Good luck!.
