Mireille Mortimer (she/her)

Lawyer & Lead Investigator

Mireille Mortimer is the founder and principal of Mortimer Khoraych PC. Mireille’s practice focuses on three core practice areas: external workplace investigations, culture audits, and workplace restoration. Over the past 13 years, she has conducted investigations into hundreds of claims relating to harassment, sexual harassment, bullying, workplace violence, discrimination (including unconscious bias, micro-aggressions, and racism/Anti-Black Racism), equity, conflict of interest, safety, dishonesty, theft, abuse of power/authority, reprisal, and code of conduct, privacy and other policy breaches, among other workplace issues.

As an experienced workplace investigator with a background in labour and employment law, psychology, and empirical research:

  • Mireille is compassionate and respectful with all participants throughout the investigation process, building rapport and offering a non-judgemental space in which to share their evidence, knowledge and information
  • She acts as a neutral fact-finder, leveraging her understanding of human cognition, perception, and memory to assess the reliability of witness evidence in order to deliver clear and substantiated findings.
  • Mireille trains individuals to overcome interpersonal conflict in the workplace in her capacity as a workplace mediator. Depending on the circumstances, she draws on a variety of training, restorative justice, and remediation methodologies to promote a healthy, productive, and rewarding work environment.

Prior to establishing Mortimer Khoraych, Mireille practiced at a preeminent national labour and employment law firm for more than a decade. There, she advised and represented clients on all aspects of the employment relationship. She has appeared before labour arbitrators and administrative tribunals (including the Human Rights Tribunal of Ontario) and stood before the Ontario Court of Appeal as lead counsel.

Mireille completed her Juris Doctor at the University of Toronto where she also received her Honours Bachelor of Science degree with Distinction, specializing in psychology and minoring in sociology. She was called to the Ontario Bar in 2008. She holds a certificate from the Association of Workplace Investigators, the only accredited workplace investigations program in North America, as well as a certificate in Administrative Investigations from the Ontario Ombudsman.

Mireille is a member of the Government of Canada’s roster of Federal Investigators (for federally regulated workplaces), in addition to being a member of the Investigations Unit for the Sports Dispute Resolution Centre of Canada. From 2012 to 2014, she served as Director on the Board for Alternatives Mental Health Agency, and as a mentor for both the Alumni-Student Mentorship Program at the University of Toronto, Faculty of Law, and the Massey Centre.
