Muir lived in several small towns in Alberta until she was sent to the Red Deer institution. The education she received there did not prepare her for life on the outside, but after she left the institution and escaped from her mother's custody and at the age of 20, she learned quickly and worked in several cities in Western Canada as a waitress, a retail sales person, and a baby sitter, caring for as many as six children at one time. Only when she married did she learn the awful truth about the sterilization. After winning her case in court, her story was featured in a documentary by the National Film Board of Canada. She spoke at several public forums in Canada, The United States and France, and she ran for election to the Alberta legislature for the New Democratic Party. Recently she was designated a Game Changer on the CBC radio show The Currents, and her story was dramatized in the play The Invisible Child at the Edmonton Fringe theatre festival. She now serves as a board member for the Living Archives of Eugenics project at the University of Alberta.
