My case is pretty much similar to yours. I ordered the second set of notes on December 13 which I haven't yet received. In my first set of notes around 2.5 months mark since AOR, nothing had been started. I recently, a few days ago, called IRCC and a lady agent told me that unfortunately nothing has been started yet. I drew her attention that I'm only 23 days away from the end of six months timeline, she said my application will definitely be delayed and feel free to call us after the timeline is over. I asked her what's the reason that nothing has been started yet, she replied 'I don't have enough info'. She once mentioned that some information is missing in my application, I asked her twice what is it but she couldn't tell me.
Now I am wondering without even starting anything on my application how did they figure that something is missing. Let's say If they figured that something is missing, would the analyst have mentioned it in my file so that I can find from my notes that I had ordered last month? Should I trust agent's wordings, because sometimes their info is misleading?
Montreal has really puzzled me!
