Yes, it's being a long six months and still waiting!!!!
Ammar, they didn't ask for any additional document till date and as far as PCC is concerned the same was (in original) also submitted along with all other documents at the time of submission of application.
I had submitted my application in the month of November 2018 and the same was received by IRCC on 26th of November-2018 and at that time bio metrics were not required for Indians. It got started from 01st January 2019 on wards and even IRCC website clearly states that those ( obviously Indians) who applied before December 2018 and their application also accepted before this deadline doesn't need to go for bio metric.
I see. Well, on the day I received the AOR, I received also a letter from IRCC asking me to pay for biometrics. The letter says:
As of 31 July 2018, biometrics became a requirement for some IRCC applicants.
