Summary

  • An overview of the National Defence Act, including the main duties and authorities of the Minister of National Defence under that Act.

Background

  • The National Defence Act (NDA) is structured in seven parts:
    • Part I of the NDA establishes the Department of National Defence (DND) and stipulates that the Minister of National Defence (MND) holds office during pleasure and has the management and direction of the Canadian Armed Forces (CAF) and provides authority for a Deputy Minister (DM) and the Judge Advocate General (JAG). It also sets out the regulation making authorities of the Governor in Council (GiC) (for the organization, training, discipline, efficiency, administration and good government of the CAF), and the MND (for the organization, training, discipline, efficiency, administration and good government of the CAF) and the Treasury Board (for matters such as pay, allowances and reimbursement, including forfeitures and deductions). Part I also addresses the sale or disposal of materiel that has not been declared surplus and is not immediately required for the use of the CAF or for any other purpose under the NDA;
    • Part II of the NDA names the CAF and provides for the appointment of the Chief of the Defence Staff (CDS). It provides for numerous matters relating to the functioning and governance of the CAF including enrolment, promotion, release, active service, non-public property, pay and allowances, service estates and boards of inquiry. Part II also deals with grievances and establishes the Military Grievances External Review Committee (MGERC), which is mandated to provide findings and recommendations on defined types of grievances to the final authority in the CAF grievance process, the CDS or their delegate;
    • Part III of the NDA is the Code of Service Discipline (CSD). The CSD sets out the foundation of the military justice system including disciplinary jurisdiction, declaration of victims' rights, service offencesFootnote 1, punishments, arrest and pretrial custody, organization and procedures of summary hearings (jurisdiction, sanctions, and review) and courts martial, sentencing appeals, and post-trial review;
    • Part IV of the NDA deals with complaints about or by military police. It establishes the right to make complaints about the conduct of military police, and the right of military police to make complaints about improper interference with an investigation. It establishes the Military Police Complaints Commission (MPCC), and it sets out the roles and responsibilities of the Canadian Forces Provost Marshal and the MPCC receiving, reviewing and responding to complaints;
    • Part V is entitled, "Miscellaneous Provisions having General Application." It includes the ministerial powers to authorize military manoeuvres in Canada, to authorize the CAF to perform any duty involving public service, and to authorize CAF assistance in federal law enforcement matters;
    • Part V.1 of the NDA, which previously pertained to the Communications Security Establishment (CSE), has been repealed and the authorities and the accompanying accountability and transparency measures for the CSE now reside in the Communications Security Establishment Act;
    • Part VI of the NDA governs CAF service in aid of the civil power. The CAF, or any part of it, is liable to be called out for service in aid of the civil power by the Attorney General of an affected province if there is a riot or disturbance of the peace that occurs or is likely to occur and is beyond the powers of the civil authorities to suppress, prevent or deal with; and
    • Part VII of the NDA prescribes certain offences, relating to the defence of Canada, which are capable of being committed by members of the public as well as by CAF members and which are triable by civil courts.

Conclusion

In the legislative sphere, the NDA provides the legal basis for numerous matters relating to the DND and the CAF. It establishes duties and grants authority to the minister and other actors to deal with a variety of matters. Authority is also found in several other statutes. Domestic CAF operations, such as those involving public service support to civil authorities or assistance to law enforcement will generally find their domestic legal authority in the NDA. However, certain types of domestic operations, and nearly all international operations, find their domestic legal authority in an exercise of the Crown Prerogative by the executive, rather than via legislative authority in the NDA.
