For all those waiting since October like me - I just got off a call with IRCC agent and this time it was much more informative - a bummer actually
The reason why my passports are being held up is due to my MEDICALS expiring in January 2021(current COPR in the system is valid until this period) and they don't print COPRs with less than 3 months validity. To proceed further case handling office (in my case Montreal VO) has to either extend or request for new medicals.
Also, we had a local MP follow up on our case. This was rejected 3 days back since Ottawa office was not delaying the process and they are actually waiting for an action from Montreal VO.
Knowing Montreal's pace, it's going to be a long long wait for me with the holiday season coming up
