So this is my perception about CPC-M and in no way its proven but just a guess - The applications that seem to be stuck at CPC-M are not straight forward (again this is just my opinion and I might be wrong). I can say that as my spouse's application is not straight forward - this is my second marriage and she is also a divorcee. Also, the documents we submitted with her application requires validation by specific person only as some of them are translated and requires background knowledge on marriage act of my country, etc. Therefore in my opinion, its taking time to get our turn with these specific IRCC people who are the only ones that can validate the exceptional situation of our application. I once heard my company lawyer saying that CPC-M is a very small office with only 7-8 staff members. Have they increased the staff at CPC-M or not, not sure. A
Let me ask the people on this forum, do you know/think that your applications are straight forward and still stuck at this visa office. If that's the case then my theory is not correct....but as I said, this is just my individual analysis and not backed up by any proof.
