The aim of this article is to enlighten a little known aspect of the Quiet Revolution : the emancipation of French-Canadian couples from the sexual moral restraints of the Catholic Church. Our study of this movement is based on the analysis of the actions of the Quebec Family Planning Center (Centre de planification familiale du Québec). This organization is at the core of the struggle by non-religious groups in favor of everybody’s right to contraception. By studying its ideology, social actions and various initiatives towards the federal and provincial governments, we strive to apprehend the importance of this organization in a changing society, particularly in its relations with the Catholic Church. Our article reveals that despite the important crisis that took place in the Catholic Church in the 1960s, it still exerts a great influence on this issue.
