I have a similar status to you, AOR Jan 31 FSW-O. My file is also at Ottawa. I have only asked one time and got a response on May 22. I'm glad to see someone else is in the same place as me!
I have the same question on the background verification. I specifically asked about eligibility, security, and criminality, but the reply mentioned background verifications, security, and criminality. However I've seen other posts about responses where they mention eligibility along with those 3, or just eligibility and background checks, so I'm really confused what this response means.
