In the early 20th century, eugenic policies were considered progressive among many Canadians, including some socialists, feminists, farmers and psychiatrists. Their assumption was that Canadian society could be improved by encouraging reproduction among certain groups — particularly Anglo-Saxon Protestants — and discouraging or limiting reproduction among other groups, including Eastern European immigrants and, increasingly, Indigenous people. (Similarly, immigration policies like the Chinese head tax were aimed at limiting the population of Asian Canadians.)

Many prominent Canadians of that era were advocates of eugenics philosophy and eugenic sterilization, including Dr. E.W. McBride, Professor Carrie Derick and Dr. Helen MacMurchy. Support for eugenic sterilization was also expressed in the 1920s by many prominent Alberta women, including Emily Murphy and Nellie McClung. Maternal feminists like McClung, for example, argued that women were the mothers and guardians of their “race.” They therefore championed legislation, including sterilization, which aimed to curtail prostitution, alcoholism and “mental defectiveness.”"
