In 1964 the Canadian government began to reorganize Canada's armed forces with the aim of integrating the RCAF with the Royal Canadian Navy (RCN) and the Canadian Army to form the unified Canadian Forces. The purpose of the merger was to reduce costs and increase operating efficiency. The Minister of National Defence, Paul 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." A new National Defence Act was passed in April 1967. On 1 February 1968 the Canadian Forces Reorganization Act came into effect and the RCAF ceased to exist. The three branches of the Canadian Forces were unified into a single service with the aim of improving Canada's military effectiveness and flexibility.
