  • labour human rights and constitutional law; and

  • access to justice and dispute resolution.

  • Advised the federal Pay Equity Review Task Force on the domestic and international human rights obligations which should inform the design of a federal pay equity enforcement system. This advice was relied on in the 2004 Task Force Report, Pay Equity: A Fundamental Human Right.

Gender Harassment and Violence

  • Litigated early cases in Canada in the 1980’s establishing important principles in the area of sexual harassment.

  • Co-authored 1996 law journal article, “Changing the Workplace Culture- Effective Sexual Harassment Remedies” concerning the importance of addressing the structural gender economic inequalities and power imbalances in workplaces to help prevent gender harassment and violence.

Labour, Human Rights  and Constitutional Law  

In her litigation practice over 40 years, Cornish argued many precedent setting cases which established important labour, human rights and constitutional law principles in Canada.  These included:

  • The  1997 SEIU Charter Challenge which restored the pay equity rights of over 100,000 Ontario public sector women and the 2002 CUPE et al Charter Challenge which obtained up to $414 million government funding for these restored rights.

  • She won for the Association of Ontario Midwives an interim 2014 HRTO decision which established important principles with respect to understanding the dynamics of complaints of systemic gender discrimination in compensation and ensuring access to justice for those complaints.

  • She successfully  challenged under the Charter for Ontario Justices of Peace as discrimination on the basis of age an Ontario law which mandated their retirement at age 70.


Access to Justice and Dispute Resolution

  • Chaired the Society of Ontario Adjudicators and Regulators Service Equity Committee.
