The eligibility is a 2 step process.
Step 1: an analyst or a program assistant will review your file and make a recommendation.
Step 2: An officer will then review the notes and the recommendation and make a final determination.
Only after an officer has made a determination, will your eligibility be passed. However, when a program analyst or assistant makes a recommendation, the eligibility status changes to recommended passed. When you call the call centre, they do not look into your file, but only the status, and give you that information, which may not be precise.
Only after eligibility is passed, i.e. by an officer, will the security / BGC commence.
If you want to know the precise stage where your application is at, consider requesting GCMS notes.
Alternatively, you can wait it out. But nothing to worry.
