Today attended the Oath ceremony @ Mississauga and received Canadian citizenship certificate.
They verify Landing /confirmation of permanent residence document and PR card while entering the hall and provide you a seat number. They will keep the PR card.
Ceremony started with a video play about Canada and taking Oath, then instructions from a clerk. Judge entered and delivered his citizenship speech, oath taking after the speech and then issuing certificates to all new citizens. After that, speech from a charity group head and judge did his conclusion speech followed by national anthem. Whole process took about two hrs.
Thanks everyone for all your inputs during this entire application process and good luck to everyone!
