She married Arthur Dubé in 1957 and gave birth to a son and a daughter. Her husband committed suicide in 1978, which later became a focus of public attention with the debate over the ruling in R. v. Ewanchuk. Her son died in 1994.
She was made a Companion of the Order of Canada in 2003. In 2004, she was made a Grand Officer of the National Order of Quebec.
She is currently active as the Chair of the Steering Committee of the Maison de justice de Québec, a pilot project in improving access to justice in Quebec City.
Among her more controversial decisions include her opinion in Moge v. Moge [1992] 3 S.C.R. 813 where she took a major departure from the practiced standard of judicial notice by allowing for a broad range of social studies data to be given judicial notice as a legislative fact. Another famous dissent was that of Canada (Attorney General) v. Mossop, [1993] 1 SCR 554 where she alone tried to acknowledge that the meaning of family is not fixed and should be read purposively to adapt to the changing times and it should include same-sex couples.
Her style was often openly confrontational and harshly critical of her judicial colleagues, in particular Chief Justice Antonio Lamer, which some critics felt was unbecoming a justice of the Supreme Court.
In the case of Willick v. Willick, [1994] 3 S.C.R. 670, she quoted a prior dictum made by herself in an earlier judgment, with which she "most heartily" agreed, carrying on the proud tradition of Lord Denning M.R.
