Karen Sargeant is the Chair of Fasken’s Ontario Labour, Employment and Human Rights Group. She has practiced management-side labour and employment law exclusively for more than 20 years.

Karen frequently appears before arbitrators, the Ontario Labour Relations Board, the Canada Industrial Relations Board, the Ontario Ministry of Labour Employment Practices Branch, the Human Rights Tribunal of Ontario and the Canadian Human Rights Tribunal. She has many winning decisions from all of these administrative bodies, for clients like Air Canada, Gate Gourmet Canada Inc., Humber River Hospital, Sunnybrook Health Sciences Centre and Nestle Purina PetCare.

Karen fiercely represents her clients’ interests, without compromising her professionalism and ethics. Although she is a fierce advocate, she also knows when to pursue settlement at an appropriate stage in a proceeding. At the appropriate time, and when appropriate for our client’s interests, she engages in negotiations with an objective of agreement.

In addition to her appearance work, Karen provides clients with exceptionally high quality day-to-day legal advice. She presents an accurate picture of outcomes to clients and provides practical solutions to clients’ workplace problems. In this way, she knows clients’ workplaces and has an active interest in resolving their employment issues.

Karen regularly lectures and teaches at conferences and to groups of management employees on employment and labour matters. She is also a frequent writer and was a founding editor of Fasken’s weekly bulletin, HR Space.
