Thérèse Casgrain (1896-1981) was a French Canadian feminist, reformer, politician and senator. She led the women's suffrage movement in Quebec and campaigned for women's rights and for the right to vote in Quebec elections, a right that was not won until 1940. She was also the first woman to lead a provincial political party in Canada.
This stamp was issued on 17 April 1985.
