I'll answer very briefly, and then I can ask colleagues to comment.
CSIS's role in the security clearance, the government security screening process.... We also do immigration security screening; it's a separate program. However, our government security screening colleagues provide advice to the deputy head who has requested that the security clearance be undertaken and done.
We're not a decision-maker. We don't keep track of who has clearances. We provide advice on each individual case to the deputy head who has requested that we do so.
