Sterilization of Indigenous Women in Canada

The practice of sterilization arose out of the eugenics movement and has a long, often hidden history in Canada. Sterilization legislation in Alberta (1928–72) and British Columbia (1933–73) attempted to limit the reproduction of “unfit” persons, and increasingly targeted Indigenous women. Coerced sterilization of Indigenous women took place both within and outside existing legislation, and in federally operated Indian hospitals. The practice has continued into the 21st century. Approximately 100 Indigenous women have alleged that they were pressured to consent to sterilization between the 1970s and 2018, often while in the vulnerable state of pregnancy or childbirth.
