Whether facing a worldwide merger review or a global cartel investigation – in the increasingly global environment of merger regulation and antitrust enforcement – let our Dentons Canada Competition and Antitrust team provide you with the assistance you need. We work seamlessly with our global Competition and Antitrust group of more than 90 members located in our offices in the US, Central Asia, Europe, the Middle East, CIS and the Caucasus, and the UK.

Our team is involved in some of the most significant merger reviews and class actions in Canada and is consistently ranked “recommended” amongst Canada’s leading antitrust practices by Global Competition Review. The members of our team are rated as leading practitioners in the area by Chambers Global.

Members of the team are leaders in their field, holding leadership positions in the Canadian Bar Association – National Competition Law Section, the American Bar Association – Section of Antitrust Law and the International Bar Association. They also regularly speak at conferences and lecture on competition law in Canadian law schools.

We provide strategic advice and representation in all areas of competition law:

• Mergers and acquisitions: Pre-merger notification under the Competition Act and the Investment Canada Act, including some of the most contentious foreign acquisitions in Canada.
• Cartels: Acting in criminal investigations and proceedings, including dealing with navigating the Canadian Immunity and Leniency processes and defending clients facing criminal charges.
• Class actions: Representing in class actions based on allegations of breaches of Canadian competition law.
• Investigations: Assisting when faced with search warrants, “dawn raids” and information requests by the Competition Bureau.
• Compliance: Developing and delivering compliance programs tailored to your business and conducting internal investigations.
• Advice: Assisting you with gauging risks from joint ventures as well as distribution and pricing practices.
• Marketing and advertising: Advising regarding marketing and advertising initiatives, contests and the consumer protection provisions of the Competition Act.

When deciding to implement a MAP program, determining a class action strategy, entering into a competitively complex acquisition or joint venture, being accused of price fixing or concerned about a competitor’s conduct in the market, let our Competition and Antitrust group guide you every step of the way.
