Katherine Kay is a litigation partner and head of the firm’s competition litigation practice, and a past member of the Partnership Board, Executive Committee and Toronto Management Committee.

Areas of focus include competition, product liability, securities, corruption and other white collar cases. She is described by Chambers Global as “virtually insurmountable in the area of competition litigation” and by Global Competition Review as "arguably the best competition litigator Canada has to offer." Katherine is known for highly effective advocacy before courts and tribunals across the country, and is a first call for “bet the farm” situations, including conducting internal investigations and advising management and boards of directors. Katherine was named as one of the Top 25 Women in Litigation and Competition Litigator of the Year by Benchmark Canada, and is recognized in Chambers Global and Chambers Canada, The Lexpert®/American Lawyer Guide to the Leading 500 Lawyers in Canada and The Best Lawyers in Canada, among others.
