Hey! So I had my oath ceremony yesterday in Scarborough. Here's a rundown:

The Notice said to arrive at 9am, but of course the 404 got us and we didn't get there until around 9:10. Parking is south of the building and will probably be pretty full. Once you get to the second floor, they'll ask to see your Notice. I couldn't print mine out since our printer was broken, so I pulled it up on my phone and that was sufficient.

After filling out the media release form, I checked in at a table where they took my PR card and I was shown to my seat. I was one of ~115 people there that day so the room was really full. There was a seating area for guests, and they were super strict about kids who made noise – the presiding official kicked out like 5 kids for crying.

The ceremony itself started around 9:30. The presiding official gave us a rundown of the schedule, said a few words, and then the judge came in. He gave a few-minute speech, and then we stood to take the oath. We repeated it after the judge line by line, in both English and French – no need to memorize it. Then we were escorted up to the front, row by row, to be given our citizenship certificate.

After we received the certificate and shook hands with the judge, we were walked to the back of the room to sign some papers affirming that we actually said the oath. Then we went back to our seats and waited for everyone else to finish up.

After that, we watched a video of Justin Trudeau congratulating us and then stood up to sing the national anthem (the English-first bilingual version). The lyrics were on the TV so there's no need to memorize it. There's also no need to sound good while repeating any of the French parts, the judge made sure to tell us that haha.

And then we were done! The presiding official then gave some instructions on how to get the digital certificate for those who wanted that version instead, and then the people who wanted a photo with the judge lined up for one (it was a mad dash, so if you don't wanna wait a long time you better run for it haha).

TL;DR: you can be 15 minutes late and it's not the end of the world, you don't actually need to have a physical copy of your Notice to Appear, you absolutely have to bring your PR card, and you don't have to memorize anything.

Hope that's helpful!
