I'm a UA/*A guy, and do fly through YYZ frequently, though its been a long time since it's been in T3.

Flying DL out next month, and wondering if there are any Priority Pass lounges I can access at YYZ T3 (through CSR card). I know there are lots of Plaza Premium lounges, but when I look at T3, it seems to list 3 T3 lounges - one for use of domestic passengers only, the other 2 only for use of International passengers, by that, it means international but not US. Anyone know of a lounge I would be able to access with my PP membership?

I do realize there's an AA club (at least I think there still is), though won't have access to that, obviously.
