In the process that we undertake to provide security clearances, the Public Health Agency and the security branch of the health portfolio undertake the initial reliability checks, etc. All security clearances go through a process of verification by the RCMP and then are referred for secret security clearances to the Canadian Security Intelligence Service, which conducts reliability assessments. It sends its assessments back to PHAC security, and the final decisions are made.
In the case of these clearances, for example, when indices were raised by the Canadian Security Intelligence Service, the deputy head of the agency took the decision to revoke the clearance.
