My P1 was from Montreal as well and I have read that many of us assigned to Montreal VO were waiting a much longer time as compared to others assigned to other VOs. So you can copy the first original P1 reply you did to Montreal and use that and send it to other offices so they can do it from their side instead of Montreal. I assumed as if my VO is not Montreal.Right yeah. Drafting an email to IRCC to not sound rude or panic and kinda follow up subtly like asking for the first time is tricky. I have sent multiple emails to Montreal and multiple webforms and GCMS notes. Nothing seemed to work. Maybe this might help.
I will send an email just enquiring the delay in my application progress, hoping someone shows mercy.
