    Eugenics in Canada

    Eugenics is a set of beliefs and practices aimed at improving the human population through controlled breeding. It includes “negative” eugenics (discouraging or limiting the procreation of people considered to have undesirable characteristics and genes) and “positive” eugenics (encouraging the procreation of people considered to have desirable characteristics and genes). Many Canadians supported eugenic policies in the early 20th century, including some medical professionals, politicians and feminists. Both Alberta (1928) and British Columbia (1933) passed Sexual Sterilization Acts, which were not repealed until the 1970s. Although often considered a pseudoscience and a thing of the past, eugenic methods have continued into the 21st century, including the coerced sterilization of Indigenous women and what some have termed the “new eugenics” — genetic editing and the screening of fetuses for disabilities.

    Eugenics: Pseudo-Science Based on Crude Misconceptions of Heredity

    The following article is an editorial written by The Canadian Encyclopedia staff. Editorials are not usually updated. "Great men are almost always bad men," Lord Acton famously said. If that is so, we are going to have to tolerate flaws if we want to celebrate "great" Canadians. The eugenics movement of the early 20th century particularly tries our tolerance of several of our textbook heroes.
