Katherine Kay is a partner in the litigation and dispute resolution and competition and foreign investment groups. She has served on the partnership board and executive committee, as well as the management committee in the Toronto office. Kay leads the competition litigation group. 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 described Kay as “virtually insurmountable in the area of competition litigation” and quoted client feedback stating that “she is always on top of her game - outstanding expertise, energetic, insightful and very practical" and that she “has an encyclopedic knowledge of the antitrust practice in Canada. She is extremely bright, very responsive and has a good litigation sense." Kay 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.”
