I am a Canadian competition and advertising lawyer with significant experience counseling companies, associations, agencies, governments and other organizations on the application of Canadian competition and advertising laws. My experience includes working on hundreds of matters in the competition, advertising and regulatory law areas. For more information about my services, see services.

If a matter requires, I commonly work with other leading competition, advertising, criminal and regulatory counsel on projects to provide attentive and efficient advice to my clients.  In this regard, I often work on complex competition law and policy matters and regularly deal with the criminal and civil branches of the federal Competition Bureau.

I also served as in-house competition counsel for The Canadian Real Estate Association in Ottawa, one of Canada’s largest trade associations.

My academic experience includes four years as adjunct professor of competition law at the University of British Columbia, Faculty of Law and publishing widely in the competition law area. I am a frequent speaker at industry events and regularly contacted by the media for views on Canadian competition law and policy developments.
