ChellyCat, it sounds like you got an agent who didn't really want to bend the rules, but said "it's looking good" because you probably actually are close to the end. I believe that you are right about your IP status - you would have received IP way sooner if it just meant that Ottawa received it. I would hang tight. Compared to most applicants who received IP on August 6th, I would assume that yours actually means that it's being processed. Maybe not as quickly as it has been traditionally, but at least it's being touched.
As a May 12th applicant, I am not sure whether to believe that I am either extremely lucky with a quick processing time, or my late-blooming (92 days!) SA basically put me in the June IP queue, which may not mean my file has been touched at all.
