This article tackles the integration of intersectionality into Canadian antidiscrimination law practices by arguing that treating the grounds of discrimination discretely contributes to the further marginalization of multi-discriminated individuals and groups. After tracing the origins and evolution of the intersectional approach to discrimination, it examines the critique addressed by the proponents of intersectionality to mainstream antidiscrimination law. Drawing on a jurisprudential analysis of 30 complaint cases claiming intersectional discrimination treated in Canadian and Quebec courts in the last 20 years, the authors set up a typology of the modes of conception of discrimination by the courts: monistic, compartmentalized, additive, and holistic (intersectional). Institutionalizing intersectionality within antidiscrimination law may be a promising avenue to reconfigure equality-safeguarding judicial apparatuses so as to better enable the struggle against multiple and interlocking forms of oppression and discrimination. Yet it can also become a liberal practice of “diversity management” that obscures structural inequalities and hallows a discourse based on individual vulnerabilities.
