The national security adviser, as I spoke to earlier, is one of the most senior public servants in the country. As chief of staff for the Prime Minister, I interacted with the NSA daily, sometimes multiple times a day. It's an individual who, in my experience in government, is briefing the Prime Minister often daily—at least a few times a week—on matters of national security. It's a key position in the Privy Council in our system of government.
When it comes to the selection process for a chief of the defence staff, operationally, that individual, the NSA, is a key member of that process, who in fact led that process. When there are issues or concerns, he is the responsible individual in the Privy Council Office who would then, working with the Canadian Armed Forces senior members, with the department, access those other bodies, ensure that investigations were carried out and report the findings back to the Prime Minister's Office and the Prime Minister for any action that was necessary.
