Well Montreal in general is extremely slow in processing Outland cases. Plus in my case they requested ADR to review my job responsibilities. I believe the officers who review initial files do not understand technical terms or specific terminology in your employment letter. All they try to do is map the NOC pre-defined job responsibilities with your employment or experience letter. In my case they were not able to determine if my job roles and responsibilities are same as per applied NOC. So they requested adr. Which I submitted immediately, but to review that as well they took almost 3 months.
If they haven't asked for remedical than chances are that they have extended your medical. Generally they extend it by a year.
You can't expect them to know technical jargons of every job that exists out there. Even someone working in same industry wouldn't know all the jargons so can't expect them to know. Best course of action is to keep the job reference letter as generic as possible so that even a layman can match it to NOC. Helps to have process a little faster although right now the process times are anyways slower.
If this is the case then it would be great! Thanks a lot @cansha
