Melanie Aitken is the Managing Principal of Bennett Jones (US) LLP, which carries on the practice of Canadian law in Washington, DC, in association with Bennett Jones LLP. She is also co-head of the competition and foreign investment practice of Bennett Jones. She specializes in global antitrust and competition law and litigation, working closely with colleagues in our Toronto and other offices.

Melanie served as Canada’s Competition Commissioner, in charge of the Canadian Competition Bureau from 2009 to 2012, having previously served as the Senior Deputy Commissioner leading merger review from 2006 to 2009.

What Clients Say

 "A true expert in her area…she is also a strategic thinker and trusted advisor…"

While serving as Commissioner, Melanie led many high-profile civil and criminal matters and worked extensively with leaders of international antitrust authorities around the world on enforcement and policy cases, holding leadership roles in key international organizations, such as the Steering Committee of the International Competition Network. Melanie is credited with revitalizing the Bureau as an active enforcement agency. Most notably, she led the introduction of major amendments to Canada’s competition laws, introducing a US-style second request merger review process in Canada, and a new per se criminal cartel offence. While establishing an unprecedented successful litigation record for the Bureau, Melanie initiated a landmark case that liberalized the Canadian real estate industry, brought cases forward in significant matters (including a challenge to Visa and MasterCard over card acceptance rules, and a challenge to a major airline merger to monopoly); during her tenure, the Bureau won the first court-ordered merger prohibition since the 1990s.

What Clients Say

Melanie is the one Canadian practitioner you would turn to in a “bet the company” merger. She is hard working, always gracious, and clients love her.

Melanie was a partner at Bennett Jones and Davies Ward Philips & Vineberg before joining the Bureau in 2005. She has acted as counsel in the Supreme Court of Canada and represented the merging parties in Canada's leading efficiencies case, Superior Propane. Melanie has an active antitrust advisory, trial and commercial practice, representing major Canadian and US companies in significant matters across a broad range of industries, including financial services, large retail, telecommunications, pharmaceutical, airlines, oil and gas, consumer products and organized sport.

Howe Institute's Competition Policy Council, and sits on the Advisory Boards of the Global Antitrust Institute, Schulich School of Business (Toronto, Canada), and W@CompetitionAmericas, and has been appointed a Fellow of the American Bar Foundation.
