From what I have read on other posts, missing addresses MAY be good cause it may mean that they are working on your case. Could mean absolutely nothing of course, those CIC people are a law unto themselves.
I did speak to our immigration lawyer today, and she did say that if there was a problem with our application, we would know because they have to give us a chance to answer any queries, and they can't just turn us down without exhausting all avenues. She did say that if our VO is not very organised, they may have missed something like RCMP checks or something, and they might be still outstanding because they weren't asked for until late in the process and that may be holding things up. Honestly we have both aged so much in this process. Wonder if it is really worth the stress.........
