October 18 is Persons Day in Canada.

It marks the day in 1929 when the historic decision to include women in the legal definition of “persons” was handed down by Canada’s highest court of appeal. This gave some women the right to be appointed to the Senate of Canada and paved the way for women’s increased participation in public and political life. Though this decision did not include all women, such as Indigenous women and women of Asian heritage and descent, it did mark critical progress in the advancement of gender equality in Canada
