The Mouvement laïque québécois (MLQ) (unofficially, the 'Quebec Secular Movement') is a non-profit organisation whose goal is to defend and promote freedom of conscience, separation of church and state, and secularisation of public institutions in Quebec. It was founded in 1981, developing broader goals from an association devoted primarily to the secularisation of public school curriculum in Quebec.
It won a major victory with Mouvement laïque québécois v Saguenay (City) (2015) when the Canadian Supreme Court ruled that it was unconstitutional for the City of Saguenay, Quebec (or any level of government) to open public meetings with prayers, or to have religious symbols in municipal facilities. The Court said that the state must maintain neutrality in public affairs.
The MLQ believes that ethics and religion should not be united within a single school curriculum. Both are taught in public schools within the "ethics and religious culture" curriculum. The MLQ was founded in 1981 by parents who disagreed with the Quebec public school system including only Catholic or Protestant religious education as requirements of the general curriculum; they thought there should be secular alternatives. The MLQ developed from the AQADER association (Quebec association to ensure the application of the right to be exempted from religious education, or "Association québécoise pour l'application du droit à l'exemption de l'enseignement religieux") founded in 1976. MLQ founders wanted an association whose scope would extend beyond the right to exemption, for instance by promoting values such as free thought. Their goal was secularisation of Quebec public institutions.
In 1987, the MLQ collaborated with senator Jacques Hébert to prevent the adoption of a private bill that would have enabled Opus Dei, a Catholic lay organization, to bypass Canadian fiscal law as a religious institution. In the same year, the MLQ petitioned the Federal Department of Justice to withdraw Bibles from courts, so that solemn affirmations to be recognized as valid.
