ABSTRACTThis article offers a feminist critique of existing sex education policies and programmes in Canada, as well as examining common right‐wing arguments against more progressive approaches. Two major forces shaping adolescent girls’ developing sexuality—male sexual violence and compulsory heterosexuality—are discussed, and recent initiatives in Ontario to introduce these issues into sex education programmes evaluated. Toronto Board of Education's new policy on sexual orientation and the Ontario Ministry of Education AIDS Education Curriculum are assessed and strategies for anti‐sexist, anti‐heterosexist sex education developed.
