# Department of National Defence (Canada)

The Department of National Defence (DND; French: Ministère de la Défense nationale) is the department of the Government of Canada which supports the Canadian Armed Forces in its role of defending Canadian national interests domestically and internationally. The department is a civilian organization, part of the public service, and supports the armed forces; however, as a civilian organization is separate and not part of the military itself. National Defence is the largest department of the Government of Canada in terms of budget, and it is the department with the largest number of buildings (6,806 in 2015).
The department is responsible to Parliament through the minister of national defence – Bill Blair as of February 2024. The deputy minister of National Defence, the senior most civil servant within the department, is responsible for the day-to-day leadership and operations of the department and reports directly to the minister. The department exists to aid the minister in carrying out their responsibilities within the Defence Portfolio and provides a civilian support system for the Canadian Armed Forces. Under the National Defence Act, the Canadian Armed Forces is a completely separate and distinct organization from, and is not part of, the Department of National Defence.

## History

The Department of National Defence was established by the National Defence Act, which merged the Department of Militia and Defence (which was created in 1906 when the British Army withdrew its forces stationed in Canada), the Department of Naval Services (the department responsible for the administration of the Royal Canadian Navy), and the Air Board (which oversaw aviation in Canada). The National Defence Act was passed by the Parliament of Canada on June 28, 1922.

## Defence Portfolio

One of the roles of the Department of National Defence is to support the minister of national defence in the administration of the 'Defence Portfolio', which comprises the Canadian Armed Forces, the Communications Security Establishment, Defence Research and Development Canada, and the Department of National Defence. These organizations are responsible to the minister. The department is not responsible for all of these organizations itself but rather exists to support the minister in carrying out the minister's duties within the Defence Portfolio.
The post of associate minister of national defence, who is also a member of the Cabinet, also exists and takes on files as assigned by the minister of national defence. Since forming government in 2015, Prime Minister Justin Trudeau has assigned the post of associate minister as an additional role of the minister of veterans affairs, who heads Veterans Affairs Canada, another department outside the Defence Portfolio.
