The unification of the Canadian Armed Forces took place on 1 February 1968, when the Royal Canadian Navy, Canadian Army, and Royal Canadian Air Force were merged to form the Canadian Armed Forces.
A white paper was tabled in the Parliament of Canada on 26 March 1964 by the Minister of National Defence, Paul Hellyer, and the Associate Minister of National Defence, Lucien Cardin. This document outlined a major restructuring of the three separate armed services, describing a reorganization that would include the integration of operations, logistics support, personnel, and administration of the separate branches under a functional command system. The proposal met with strong opposition from personnel in all three services, and resulted in the dismissal of the navy's senior operational commander, Rear Admiral William Landymore, as well as the forced retirements of other senior officers in the nation's military forces. The protests of service personnel and their superiors had no effect, however, and on 1 February 1968, Bill C-243, The Canadian Forces Reorganization Act, was granted Royal Assent, and the Royal Canadian Navy, the Canadian Army, and the Royal Canadian Air Force were combined into one service: the Canadian Armed Forces.
The public explanation for the reorganization was that unification would achieve cost savings and provide improved command, control, and integration of the military forces. Hellyer stated on 4 November 1966 that "the amalgamation... will provide the flexibility to enable Canada to meet in the most effective manner the military requirements of the future. It will also establish Canada as an unquestionable leader in the field of military organization." However, the then-serving Liberal ministers of the Crown were accused of not caring for the traditions behind each individual service, especially as the long-standing navy, army, and air force identities were replaced with common army-style ranks and rifle green uniforms. Rather than loyalty to each service, which, as military historian Jack Granatstein put it, was "vital for sailors, soldiers, and airmen and women" who "risk their lives to serve," Hellyer wanted loyalty to the new, all-encompassing Canadian Armed Forces (CAF); this, it was said, caused damage to the esprit de corps for sailors, soldiers, air crew and other personnel.
