They sent me an ADR today for military records or proof of exemption (I'm from one of the more problematic countries lol). Submitted exemption records right away. Not sure if this means I'm bound for a comprehensive security now.
I think the question was more along the lines of how background check going from in progress to in progress again implies comprehensive security. I'd be curious to know too if you have any specific knowledge pertaining that.
Just to be clear, your eligibility in the tracker changed from not started to in progress on Monday Sept. 1 (a stat holiday), and you got an ADR the following day?
I just called IRCC for the first time and they said my PVO is Edmonton just like yours (which made me anxious since I don't hear much about this particular office), so now waiting for a decision or some sort of update I guess.
