Mary retired from the firm effective December 31, 2017. Mary was a partner at our firm, acting in the areas of human rights, pay equity, labour, constitutional, administrative and employment law.    Mary was recently awarded the Order of Canada and an honorary doctorate at York University for her work over the last 40 years. Her Order of Canada citation summarizes her key accomplishments:

“Mary Cornish has devoted her career to advancing equality rights.  A human rights lawyer, she was a central figure in the Jane Doe case which exposed discriminatory police practices in Toronto and was a leading voice in the fight to create Ontario’s Pay Equity Act. She has devoted countless hours to the most important pay equity challenges of our time and has successfully obtained fair pay for hundreds of thousands of women workers. As the Chair of the comprehensive review of Ontario’s Human Rights Code, she was also called upon to craft the recent modernization of the province’s human rights system.”

Mary’s practice is being continued by other lawyers in the firm as follows: 

Labour and Human Rights:  Please contact Kate Hughes.
Pay Equity:   Please contact Jan Borowy.
Employment Law:   Please contact Stephen Moreau.

While taking time to enjoy her retirement and spend time with her family and grandchildren, Mary will also on a part time basis provide strategic expert advice through Cornish Justice Solutions and can be contacted at

On behalf of everyone at Cavalluzzo, we wish to congratulate Mary on her retirement and thank her for the many contributions and accomplishments as a leading human rights and labour lawyer and a partner at the firm.
