Reminder: there are often Oath ceremonies which are not publicized on the IRCC website (I have no idea why many are, while many others are not), and attended by candidates who are not participants here or by participants who do not report specific information about their own application.
Odds are high that, indeed, there are at least TEN THOUSAND taking the oath in any given month, and in some months it can approach double that.
And it is very likely there are, thus, scores of oath ceremonies every month for the local offices around the GTA, many of which are in effect unreported.
