With her father losing his job in the mid-1930s, the Great Depression caused financial difficulties for the family. As a result, the three sisters entered show business as vaudeville performers to support the family. They began touring in Canada and the United States. Collectively, they were known as The Three Brodels. As an attempt to bypass child labor laws at the time, both Mary and Joan pretended to be older than they were. When Leslie was nine, she told child labor investigators that she was 16 years old. Joan proved to be the scene stealer of the three sisters because of her impersonations of figures such as Katharine Hepburn, Maurice Chevalier, and Jimmy Durante. Coming from a family of Irish ancestry, Leslie was raised as a Roman Catholic and attended Catholic schools in Detroit, Toronto, and Montreal.
