If you know a couple of Mississauga applicants, you'll see they are complaining about the long delays too, i know a few and things aren't rosy on that side as well.
I struggled during my 5+ months wait (after DM) to understand how Scarborough works..but wasn't able to understand the logic, i freaked out at times, lost my patience but that didn't change anything....eventually i cancelled all my travel plans and relaxed...only then the Oath invite came in.
My guess is there could be a few possible explanations for the perceived "quiet period"/or a combination of all:
1) The website hasn't been updated (we've seen in the past that it may be lagging a week or 2 behind at times)
2) The rate of scheduled ceremonies has slowed down temporarily (due to whatever reason - could be people taking time off/or anything else)
3) Someone also pointed out earlier that they could be taking a long time because of sorting nationalities in the background - to ensure ceremonies
are as diverse as possible (it cannot be a coincidence that everytime a ceremony of only 80 to 88 people come from 30+ countries)
To conclude, its best to remain patient and try to enjoy the rest of the summer and everyone's turn will come.
