Practice Areas

Katherine Kay is a partner in the Litigation & Dispute Resolution and Competition & Foreign Investment Groups. She has served on the Partnership Board and Executive Committee, as well as the Management Committee in the Toronto office. Katherine leads the competition litigation group and her practice is concentrated on complex commercial litigation, often involving the interplay between regulatory, civil and criminal law regimes, and across multiple jurisdictions. Chambers Global has described Katherine as “virtually insurmountable in the area of competition litigation” and quoted client feedback that “she is always on top of her game - outstanding expertise, energetic, insightful and very practical" and “has an encyclopedic knowledge of the antitrust practice in Canada. She is extremely bright, very responsive and has a good litigation sense". Katherine was recently noted in the Global Competition Review’s Country Survey: Canada as one of Canada’s “headline competition litigators” and as “among the most talented and well-regarded in the country”. She was also described in previous GCR Country Surveys as “arguably the best competition litigator Canada has to offer”. She is lead counsel on a broad range of cases dealing with all aspects of competition law, including criminal defence work, class and other civil actions, mergers, abuse of dominance and other reviewable matters before the Competition Tribunal.
