More than 4000 women served as military nurses during the Second World War playing a vital role in the care and comfort of wounded soldiers, sailors, and airmen. As commissioned officers known by rank and title as Nursing Sisters, they served as fully-integrated members of the Royal Canadian Army Medical Corps, the Royal Canadian Navy, and the Royal Canadian Air Force. Most of them worked overseas in military hospitals and casualty clearing stations. After the lean years of the 1930s when there were few available positions for graduate nurses, even with the dangers of warfare, military nursing offered a job with a good salary, benefits, status, and a chance to travel.
