Department of Militia and Defence in the context of "National Defence Act"

The National Defence Act (NDA; French: Loi sur la défense nationale; LDN) is an Act of the Parliament of Canada, which is the primary enabling legislation for organizing and funding the military of Canada. The Act created the Department of National Defence, which merged the functions of the Department of Militia and Defence with the Department of the Naval Service and the Air Board, after its passage in 1922 and its implementation on 1 January 1923. At that time, and until the passage of the National Defence Act of 1950, the Canadian army was still governed by the UK's Army Act.
