Quick update for those looking to book appointments at Passport Service Offices - they are offered a month in the future. (Eg: today is March 6th, you will most likely get an appointment for April 5th). The reason I know this is because I booked two appointments a day apart, just as a back up in April, 6 days after my Oath.How to find out, if my service canada location has 10 business days or 20 processing time?
Appointments open at 7 PM sharp and remain available until 9 PM or so (at least from what I have seen, not sure if they get filled or the office closes them).
Book only at Passport Service Offices because you may get your passport way faster from there.
TIA.
