The Brattle Group provides economic analysis and expert testimony to private parties and the Competition Bureau under all sections of the Competition Act, including the merger, monopolistic practices, cartel and deceptive marketing practices provisions, and in regards to advocacy initiatives.

We have advised clients in hundreds of transactions, providing testimony and litigation support in antitrust and competition cases on behalf of leading law firms as well as U.S., Canadian and international government agencies. Our Canadian competition practice is led by Toronto-based Principals Dr. Renée Duplantis, former T. D. MacDonald Chair of Industrial Economics at the Competition Bureau, and Andy Harington, a proven expert in competition matters including M&A transaction advisory. They are supported by a deep and knowledgeable team including former Competition Bureau officer Ian Cass, Dr. Dimitri Dimitropoulos, Dr. Jonathan Lee and Parham Nasseri.

The Brattle Group has a proven track record acting for both Canadian and multinational clients providing services in the following areas of competition law:

Mergers and Agreements

We assess whether transactions are likely to result in a substantial lessening or prevention of competition and whether potential mitigating factors exist, including the section 96 efficiencies defense, section 93(b) failing firm defense and likelihood of a timely new market entry. We are called on to provide these analyses throughout the deal process, from an early assessment of deal risk to situations where a transaction has been challenged by the Bureau.

Monopolistic Practices

We provide investigative and expert witness services relating to allegations of restrictive trade practices, including predatory pricing and abuse of dominance. 

Class Actions

We have expertise at the class certification stage in performing statistical analyses of detailed sales data or analyzing market structure and wide-ranging experience in the estimation of cartel overcharges using a variety of techniques.

Deceptive Marketing

We provide investigative and financial consulting services in the context of alleged deceptive marketing services, including the estimation of damages or incremental benefit derived by the defendant company.

Sections 100 and 104

We have significant experience assessing whether the ability of the Tribunal to remedy the wrong will be substantially impaired, reflecting our cross-functional knowledge of the business processes, intellectual property and mergers and acquisitions.
