"In 1928, the Province of Alberta, Canada, passed legislation that enabled the government to perform involuntary sterilizations on individuals classified as mentally deficient. In order to implement the Sexual Sterilization Act of Alberta in 1928, a four-person Alberta Eugenics Board was created. These four individuals were responsible for approving sterilization procedures. In 1972, the Sexual Sterilization Act was repealed, and the Eugenics Board dismantled. During the 43 years of the Eugenics Board, it approved nearly 5,000 individual sterilizations, and 2,832 procedures were actually performed."

FYI, Alberta was the first part of the British Empire to do this. It's disgusting.
