Just my personal opinion,
It looks like the CIC starts showing some progress, we should understand that
1. Whenever there is new "system" changes especially in the early stage, staff use them always take times to get this systems better or they learn how to use the system more efficiently. each module of system can be similar or entirely different than the other or old ones. The individual CIC staff example the call centre staff might not have in depth knowledge about the whole picture, also the specific question we asked them everyday. If your IT person, you will know what I meant.
2. The Ottowa or the rest of LVO, which is faster than the others, it's hard to tell simply again, because the processing system became globally don't quote me on this as past experience definitely can be good reference, but might no be more reliable in some cases.
3. The concept of " Transfer" is no long the old school - physical paper work shipping around globally by couriers, the files in the CIC computer systems "cloud?"the VO staff can login work on from everywhere in the world based on their access code and files assign to them. Even you call air canada to claim luggage lost it will be someone in Indian to handle that for you. Point taken?
4. It might be delays in some cases the reasons can be totally complicated with multiple factors. Example the addeess change: if CIC has forwarded the file to LOV based on the "home address" it actually base on the "Nationality" of the applicant, that is why we see some one's Canadian address on file in the original form in the first place but files is still going to home region LVO, and confused by in home country address but file is in Ottowa
Long story short, people who have case numbers in hand and files have been assigned, take break, relax, changing address to your Canadian address is not something difficult to do, "if you want to be "EXTRA CERTAIN" wondered you r going to miss correspondence from CIC," this is what I was told by CIC agent .
