In the 1950s, the recruitment of women was open to roles in medicine, communication, logistics, and administration. The roles of women in the CAF began to expand in 1971, after the Department reviewed the recommendations of the Royal Commission on the Status of Women, at which time it lifted the ceiling of 1,500 women personnel, and gradually expanded employment opportunities into the non-traditional areas—vehicle drivers and mechanics, aircraft mechanics, air-traffic controllers, military police, and firefighters. The Department further reviewed personnel policies in 1978 and 1985, after Parliament passed the Canadian Human Rights Act and the Canadian Charter of Rights and Freedoms. As a result of these reviews, the Department changed its policies to permit women to serve at sea in replenishment ships and in a diving tender, with the army service battalions, in military police platoons and field ambulance units, and in most air squadrons.
