Mandate
The CFNIS investigates serious or sensitive service and criminal offences against property, persons, and the Department of National Defence. It has authority and jurisdiction over persons subject to the Code of Service Discipline (CSD), wherever Canadian Forces are established or deployed throughout the world, regardless of rank or status. Civilians deployed with the military can also be subject to the Code of Service Discipline. In addition, like all members of the Canadian Forces Military Police, personnel of the CFNIS have the authority to lay criminal charges in civilian court in cases where civilians break the law on or in relation to military property.
