“Only after an officer makes a final determination on eligibility, will the security screening commence.” Check the screenshot with statuses from GCMS notes after this citation - all statuses are passed there besides Security.

I can confirm it’s same for me - all stages green on the tracker and statuses all passed, only Security is blank in the notes, despite COPR numbers being issued and having expiring validity. Also notes mention officer requesting RFV to be sent, but they redact Security in GCMS notes, so I can’t see that he sent the application to Security but apparently he only sent it at this stage because up until Jan23 I used to receive CBSA notes and saw notes unredacted and there was nothing lately on Security.
