i'm not sure how that would factor in since mississauga checks the application for completeness and files are transferred to ottawa once they are deemed "complete". there's really no knowing why visa offices slow down and speed up except for application volume. watching the general visa office processing since april, there does seem to be some rotation for quick processing. when i first applied, syndey, australia and paris were superquick (3 months), then it changed to ottawa and apps that stayed in mississauga, now it seems vienna is an office that is speeding up. i have no idea if the rotation is "real" or if it's just a random coincidence. unfortunately, we will probably never know. right now, the processing is pretty standard for ottawa, based on 2013 and early 2014 applications prior to the fast tracking seen this summer.
