I just spoke with IRCC. They said my primary office is Vancouver. Secondary is CPC Sydney. Event office is Calgary (for oath/test). I applied out of Calgary.
We also checked my wife's separate application, and hers is the same. It's just odd that her background is complete and mine is not. I received the test invite and she has not. Her AOR is a bit behind mine, but I would have expected a pre-test GU by now.
Also, they told me my security is done, but criminality is in progress. She agreed I may get a FPR, but since my wife's is complete, she will not.
All in all, I don't know much more than I already knew, but it's very interesting that my application is apparently being processed in Vancouver, not Calgary, so I'm grouped with a lot of other people, I presume.
