The Army Cadet League of Canada (League) was officially formed in 1971 to work with the Department of National Defence (DND) in support of Army cadets and has a branch office in each of the provinces and the territories.

The League is the supervisory sponsor for more than 400 cadet corps across Canada. With the aid of each branch office, the League ensures financial, accommodations and transportation support for programs and services not provided by the Department of National Defence to more than 18,000 Army cadets.
