Thank you for the question, Mr. Chair.
The function of procurement within the government is centralized with another department, PSPC. Within our department, it is authoritatively controlled by another assistant deputy minister in charge of materiel. I can tell you from experience that we have used the national security exemption when we're dealing with sensitive national security issues or concerns when procuring IM/IT capabilities. On the integrity of our procurement or supply chain, I would have to defer that question to my colleagues, who are the experts and the authoritative voice in that area. I don't procure my own contracts. I need to use those authorities to do that.
