My girlfriend is in need of urgent (24-hr) processing for her passport application, so we'll be needing to make a trip to the Mississauga passport office. I've been trying to find information on how early we'll need to arrive, so I can know when to schedule flight times most effectively. However, there's no real solid information on this.

My questions on the issue are:

* What are the specific situations which allow for urgent processing?
* What time do offices stop accepting applicants in line for processing (cut-off time)?
* Is this cut-off time the same for urgent processing applicants?

If anyone has a somewhat authoritative answer to these questions, it would be very helpful.
