His Majesty the King v. Olivier Chatillon (40331)

Posted on: 2023-06-13



After a trial in the Court of Québec, the respondent, Olivier Chatillon, was convicted of one count of sexual assault of a child. The trial judge held that the prosecution’s case could be based on the admissions made to the professionals who had assessed him, although he had met with them during an entirely voluntary therapeutic process to receive treatment for problems associated with substance abuse and sexual deviance. The Court of Appeal, for the reasons given by Vauclair J.A. and concurred in by Healy J.A., granted the motion for leave to appeal, allowed the appeal and acquitted the respondent. It declared that the admissions were inadmissible in evidence based on its analysis of the Wigmore criteria for privilege. Mainville J.A., dissenting, would have dismissed the respondent’s appeal on the ground that the admissions were admissible because they were not privileged. By consenting to the disclosure of his admissions, the respondent had expressly waived their confidentiality.
