Hey!
I'm in a slightly different situation, but also waiting on administrative processing at the MTL embassy right now (did my CR1 visa interview on Aug 3rd and had to resubmit my rcmp background check that was wrong the first time. UGH.).
From what I gathered from my interviewing officer, this site, and my lawyer is that it can be anywhere from 4-8 weeks to have them process whatever we send in, no matter what it is. 6 weeks is an often quoted time. So, it sounds like you're still in typical wait time range unfortunately. But it's encouraging to see movement on your file on the 16th, hopefully it comes soon for you!
I also needed to travel abroad while I've been waiting and didn't want to ask for my passport back. So, I got a temporary duplicate passport as explained in this post:
It was a surprisingly easy and quick process for me at the downtown Toronto passport office. Might be worth it if you have the money to throw at the problem. (I will note, mine temp passport doesn't have a white cover like in the photo!)
Good luck - I hope you make your travel plans and clear this whole messy process soon!
