Indeed, the clearance process itself requires individuals to declare many details of their past affiliations, lives and work. We do verify, through our security office and our chief security officer, those declarations. For all public servants who have clearances, there are checks done through the RCMP—criminal—and also through the Canadian Security Intelligence Service to verify, as well as through open and other sources of public information.
Where individuals seek to hide clandestinely other aspects of their intentions, it's very important that we have policies and procedures that are designed to provide tripwires, if you will. This enables us to flag areas for further investigation and research. It will also ensure that there is oversight and there are additional layers of approval for events if, indeed, the previous checks and clearances don't reveal some of those covert intentions.
What we have done is put additional layers that allow us to do additional steps and to have additional sets of eyes looking at approvals to make sure that there are multiple keys, if you will, to unlock different processes, approvals, collaborations and affiliations. For us, it is about trusting, but it's also about verifying. Our security services help us to do that, and our policies and procedures in the area of security help us to be continually vigilant.
That's what is really required here. It requires continual vigilance and awareness, and it requires individuals to act and flag things they see that might not be quite in line with policies. That's a culture, and that is the culture that we're building at the Public Health Agency through the processes that we've put in place since these incidents, now over four or five years ago.
