Hi everyone,
Sharing my experience at Brampton passport office on Aug 18th.
TLTR: I am from Mississiauga. Was able to get my application submitted in 3.5 hours. Definitely recommend the strategy below and Brampton office to anyone.
After hearing nightmares about people camping overnight for beating the queues, I decided to go around the noon instead (after a ton of research and an option of trying again the next day), I decided to try my luck and went to the Brampton centre around 12.30pm. And I was so surprised to see just a handful of people ahead of me in the queue! But I indeed got lucky as the queue got cutoff right after me! While the queue didn't move for about two hours, however, since I had received the token as soon as I had arrived, I was almost guaranteed that I would be allowed inside. At about 2.45pm, I was finally allowed inside and it felt great! the process inside took about 1.5 hours and I was done by 4pm. I would highly recommend that you try this centre, staff if very efficient and courteous. Just be patient and don't be rude to the security guy outside (a few people in my queue were very rude and it wasn't nice). Hopefully, you will get a 10 year passport soon and then the hard work of 1 or 2 days would be all worth it
