Davies Ward Phillips & Vineberg LLP

Davies Ward Phillips & Vineberg LLP's Toronto-based team combines its top-tier M&A offering with strong litigation expertise to provide comprehensive service on competition, antitrust and foreign investment law. The  team is distinguished in part by the depth and experience of its bench, which makes it a popular choice for resource-heavy and high-stakes cases, where it routinely acts for major domestic and multinational clients. Among its headline merger filings, John Bodrug was selected by Aecon Group to advise on its C$1.5bn acquisition by China’s CCCC International Holding; the deal obtained clearance under the Competition Act but was ultimately blocked under the Investment Canada Act. Former Commissioner of Competition George Addy, who recently stepped down to senior counsel, and former Senior Deputy Commissioner of Competition, Adam Fanaki, are highly sought after for their specialist in-house experience. Also recommended are Anita Banicevic, who handles a range of merger review, criminal and civil investigations and compliance matters, and competition litigator Sandra Forbes. Jim Dinning has been singled out as an up-and-coming star.

Bennett Jones LLP

Bennett Jones LLP excels in contentious work, where it has strengths across the full gamut of civil and criminal matters. A regular fixture in complex antitrust disputes, the group has litigated both for and against the Bureau. Jointly led by Washington DC-based Melanie Aitken (former Commissioner of Competition) and prominent Toronto-based competition expert Randal Hughes, the team is also routinely engaged to advise on domestic and multi-jurisdictional merger reviews. Toronto-based litigator John Rook QC is another of the team's senior contacts. In addition, the department benefits from an impressive band of up-and-coming partners including Adam Kalbfleisch, who handles an array of competition, foreign investment review and regulatory matters, and litigator Emrys Davis, who was promoted to partner in 2018.

Practice head(s):

Melanie Aitken; Randal Hughes


Bennett Jones is our go to firm for competition in Canada. The team is very user friendly and its guidance has proven itself time and time again.’

The Bennett Jones antitrust and competition team, headed in Canada by Randal Hughes, is an exceptional group with strength across the board in antitrust and competition matters.

Randal Hughes is hands down the best competition lawyer in Canada. He has the respect of the Bureau, his peers in Canada, and the international antitrust community. Emrys Davis is a very strong up-and-coming member of the antitrust team, who also has great strengths across the board.

John Rook and Emrys Davis are the best two antitrust litigators in Canada. John Rook is extraordinarily experienced and seasoned with superb judgment; he is also, unlike many Canadian counsel, not at all reluctant to take on the Competition Commission. Emrys Davis is John’s protégé and is extremely insightful with excellent strategic instincts.
