The size of the Canadian Armed Forces in 1970 was 98,200 Officers and all ranks. The Defence cuts were under way, Caused by PM Trudeau,the goal being to reduce the Canadian Armed Forces to 83,000 all ranks and Canadian Forces Europe was cut from 10,000 personal to 5,000. The Air division being gutted(Losing its nuclear strike role) as well as 4 Mech brigade being gutted. As far as 1950 goes you have the complete opposite of the 1970 situation. The three separate services were expanding to meet the cold war setting up the Air division in Europe training a brigade ,and fighting a war in Korea. The Royal Canadian Navy planned for a 100 ship Navy.The official strength was suppose to be 51, 000 but was much lower and by 1953 the Armed forces of Canada stood at 105,000 officers and servicemen . The highest peacetime strength of Canada's Armed services were in the early 1960s 123,500 officers and service personal. After int ergration of the three services strength stood at RCAF:48200, Cdn Army46,500 and the RCN at 19,700. As the 1960s dragged on the services slowly became the Canadian Armed Forces service strength was suppose to be at 100,000. The decline began with Paul Hellyer at the unification experience Hope this helps
