This case concerns the meaning of consent in sexual assault law.

LEAF intervened before the Supreme Court of Canada.


This case deals with the boundaries of consent to sexual activity under Canadian criminal law. The complainant testified that she insisted the accused use a condom during sex. The first time he used one, but the second time he did not. This raises the question: if someone is asked to use a condom, but they do not comply, is the activity considered consensual?


LEAF argued that including “sexual activity with a condom” in the definition of “sexual activity in question” promotes substantive equality for equity-seeking groups. Sexual activity with a condom and without a condom are separate acts that require separate consent. This interpretation is a principled approach that affirms and protects the dignity and autonomy of sexual assault complainants, while appropriately limiting the scope of the criminal law.


This case was heard by the Supreme Court of Canada on November 3, 2021.

LEAF is grateful to Frances Mahon and Kirat Khosa, counsel for LEAF in this case.
