Hi everyone! Montreal applicant here. I finally received an update on the tracker:
"You've been scheduled to attend your citizenship ceremony on November 12, 2021." Passed the test on June 18, DM on June 27, no other requests from IRCC. I suppose I'll receive the email with instructions a few days before the ceremony, right? Anyway, good to see the Montreal office is alive and kicking

Best of luck to all applicants, don't lose hope!
