The pace of oaths is increasing in Montreal recently based on the message on different forums / facebook groups. I saw at least 4 different dates for the first week of October (4th, 5th, 6th and 8th).
And it correlates way more with the AOR than DM... A majority of applicants that received an invite recently have an AOR in August or September 2020, only if your application is smooth (meaning no test rescheduled, non-routine, fingerprint, etc).
Wow, and us 2019 applicants (even with "no wrinkle" cases) still shuffled to the bottom of the stack. Beyond frustrating.
