The Royal Canadian Army Cadets (RCAC) can trace its history to the creation of drill associations or militia companies in 1861, predating confederation by six years. These early militia companies and drill associations were not cadet corps but were militia sub-units formed in educational and other public institutions. Enrolment was limited to men between the ages of 13 and 60. The drill was not only a parade square and discipline exercise, but a skill that was necessary for the defence of the Colony. The American Civil War and the threat of the Fenian Raids motivated their creation in Upper and Lower Canada.
