I feel you bro. Half of the applications where I live go to Hamilton. Mine HAD to be in that pile that went to dreaded Mississauga office.
I believe each application is different. I live in Milton and I am a Jan 2018 applicant. When I learned that my application is in Hamilton I was really happy knowing that it will be processed quicker. Even though I was one of the first ones to be in process since March 2018. Since then there is no update and other applicants after me are onto their Oath from Hamilton.
