Hi user828, you could ask your MP office to check to see if they received it or not. In my case, MP office informed me that the PCC has been received and no issues. Alternatively, you could request GCMS notes.
Also, regarding the processing, I believe every case is different. I heard earlier people screaming about processing times by ND LVO. What do they say after Rick2007 case. I guess there are many hidden factors, which none of us may aware, that may affect the processing. Earlier, we all were under impression that CPP-O will be faster, but so far no one received (one or two) passport requests from CPP-O, on the other hand, people got passport back with visa stamped in it.
