I agree with you. I guess March-August applicant's files have been physically transferred to CPC-V for processing. Because CIC needs time to organize files, setup facility and re-training their CIC employees here for processing, we have seen some delay happened to March-August applicants.
In next weeks, I guess March-August applicants will receive news from CPC-V whereas September-December applicants will be contacted by CPC-M. It is pretty CIC's good strategy if that happens in an effort from CIC to clear backlog I think.
I just wonder why CIC don't do background check anymore by themselves as they did. They are now asking more applicants sending RCMP police clearance. This request adds up many unnecessary months to processing time. Besides, because there are a lot of applicants sending additional documents through mails or Case Specific Form, there are good chances that CIC may lose our additional documents. I wish they would send us emails to confirm if they receive documents they asks once they get it.
