Katherine Kay is a partner with the litigation and competition departments, based in Toronto, litigating cases throughout Canada. Katherine is known as a dynamic and highly effective courtroom advocate with a razor-sharp strategic approach. She is a first call for “bet the farm” litigation and crisis management situations.
Katherine’s practice concentrates on complex commercial litigation, often involving the interplay between regulatory, civil and criminal law regimes, with particular subject matter expertise in the areas of competition, product liability, class action defence, international law, corruption and other white-collar matters. Katherine's practice emphasises the key aspects of managing multiple exposures and formulating and coordinating strategic responses, often working very closely with counsel in the United States, Europe and other jurisdictions, as well as quarterbacking internal and external investigations.
Katherine is described in Chambers Canada as having “a strategic sense as well as a level of practicality that is rare even among excellent lawyers” and “a wealth of experience in the defence of class actions involving competition, securities, product liability and consumer matters”, and in Chambers Global as “virtually insurmountable in the area of competition litigation”. Global Competition Review describes Katherine as “arguably the best competition litigator Canada has to offer” and ranks her as one of the '100 Women in Antitrust' worldwide, and Benchmark Litigation has twice named her the ‘Canadian Competition Litigator of the Year’. Other recognitions include Best Lawyers in Canada, Lexpert/American Lawyer Guide to the Leading 500 Lawyers in Canada, and Lexpert Guide to the Leading US/Canada Cross-Border Litigation Lawyers in Canada. She is a past member of the firm’s partnership board and executive committee.
WWL says: Katherine Kay has a “superb practice” in competition law, focusing mainly on litigation matters.
