Hello just giving an update, had interview yesterday Aug 23. They ask for all of your passports, ID's and verify language documents. Before attending interview the only thing complete on my tracker was Background check and Citizenship test, everything else was pending. I am October 2020 applicant.
After the interview, the immigration officer let me know they are running a pilot project where you are able to become a citizen the same day! Just need to surrender your PR card. Waited 30 min was taken into a room where I gave oath with officiant, took pictures, gave me my citizenship certificate and that was it!
I will say though that not everyone who was waiting for their interview were given opportunity to become citizen that day. I am not sure how they choose.
Best of luck to you all.
