Biography

Madeleine has over 20 years of experience in intellectual property litigation, copyright, trademarks, and entertainment law. She regularly advises companies of all sizes. Clients appreciate her direct style and the “solution mode” in which she operates.

Knowing the implications of litigation, Madeleine helps clients prevent disputes when possible. If legal proceedings become inevitable, she fully invests her rigor, tenacity, and persuasiveness into her client’s case.

Madeleine has successfully represented companies before the Federal Court, the Québec Superior Court, the Copyright Board of Canada, and various arbitrations. She regularly negotiates favourable settlements for the companies she represents. From 2011-2016, Madeleine was the president of the Canadian chapter of the International Literary and Artistic Association (ALAI), recognized by the World Intellectual Property Organization (WIPO).

Madeleine was identified as an “IP Star” by Managing Intellectual Property magazine, and is consistently among the most recommended IP professionals, according to Lexpert. She is the author of many articles and regularly gives lectures in the field of copyright and entertainment.

As a mother and mother-in-law of 3 children of primary school age, Madeleine is convinced that parenthood has made her a better, more rigorous and disciplined lawyer.
