Security in the RCN was the responsibility of the Assistant Director Naval Intelligence who reported to the Director of Naval Headquarters. With the exception of a very small group of professional Policing Canada's Military since 1917 security officers, naval security officers were primarily Intelligence Officers or officers assigned security duties as a secondary responsibility. The navy had no police organization comparable to the C Pro C or the AFP but relied upon Dockyard Police, Corps of Commissionaires, local Civil Police and shore patrols to maintain security of establishments and maintenance of discipline. Field inquiries in support of the security program were conducted by the RCMP.
