National Security Corps (Royal Canadian Gendarmerie)

The National Security Corps (RCG–NSC; French: Corps de la Sécurité nationale, GRC–CSN) is the section (corps) of the Royal Canadian Gendarmerie (RCG) concerned with major law enforcement operations within the Canadian Republic's civilian population, both domestically and abroad. It handles law enforcement operations and investigations which fall under federal jurisdiction, typically only those which are designated extremely serious and which provide the most immediate and credible threat(s) to Canada's national security or the security of senior members of the Canadian federal government. The National Security Corps also assists the RCMP, provincial police forces, and local police forces (county constabularies) with public order and security at major national and international events deemed at-risk. The corps is also responsible for providing security details to the President and Prime Minister of Canada and other senior federal government officials, as well as visiting VIPs like diplomats and other international delegates.

The National Security Corps has its headquarters at the RCG Armoury in Ottawa, and has a total of 12,433 enlisted or commissioned personnel and 3340 civilian personnel, the latter of whom are technically Department of National Defence (DND) employees. According to the National Police Act, in peacetime the National Security Corps comes under the jurisdiction of Public Security Canada, while during war it comes under DND jurisdiction. The commanding officer of the National Security Corps is Lieutenant-General Anthony B. Simmons.
