This is from another forum where they keep detailed track of processing times. This is a good quote to bear in mind (applying to those applications that are unlucky enough to end up at local VO's rather than getting processed in Mississauga)
"No, they dont process in any particular order. I suspect that means your file is assigned to a particular case officer in a particular workstream. I have recorded timelines where one case was processed start to finish in 47 days and another that took 18 months. There is no rime nor reason to it, just settle in with the idea that it will take one year and anything less is a bonus"
