Tom finds innovative, effective and efficient litigation solutions and is a passionate lawyer, who fully invests in his clients

Tom is our Litigation and Disputes Resolution Practice Lead in Toronto.

He cuts through the noise and procedural puck-ragging that can often bog down litigation, delivering client-focused strategies and solutions that protect client interests and achieve results in the most complex commercial, contractual, regulatory and professional liability cases. Tom brings enthusiasm and energy to his work and, even after over twenty-five years in practice, maintains a passionate curiosity and interest about what his clients do and to continually learn more.

Tom regularly acts as lead counsel in confidential international and domestic commercial arbitrations, building on his undergraduate and graduate work in international relations and, in particular, his experience studying international law and arbitration and working in the United Kingdom through the University of Detroit-Mercy London Law Programme.

He also regularly acts as lead counsel before all Canadian tribunals and courts, including the Supreme Court of Canada and before domestic and international arbitral tribunals. He is ranked as a top lawyer for medical negligence cases — considered among the toughest cases to litigate at trial. Since 2012 he has shared his skills and knowledge as an Adjunct Professor at Queen’s University Faculty of Law, teaching Trial Advocacy and Medical Malpractice, and since 2022 as a Sessional Instructor at the University of Windsor Faculty of Law, teaching Remedies. 

" Tom Sutton has owned us in this area. He is great – very aggressive when you need him to be, very passionate about the litigation he does. You want a lawyer who is invested in your cases and is excited about doing them. "

Driving technology in litigation

Tom was an early adopter and a firm leader in the use of legal technology in litigation. In particular, he lead the committee that created our firm’s original e-Discovery/Litigation Support platform and he now frequently collaborates with our MT>3 division and other groups within the firm to drive innovative solutions for our clients. He also saw the opportunities to leverage technology to advance litigation during the COVID-19 pandemic and has authored a chapter on virtual arbitration in “Virtual Litigation: Litigating from a Distance”.

Reputable news organizations recognize Tom as an invaluable resource and commentator on technology and law. He has appeared on CBC broadcast programs, The National and World Report, and in print publications, such as The Globe and Mail, National Post and The Lawyers Weekly, frequently commenting on issues relating to the impact of technology in litigation.

Empowering education and community

Tom has established himself as a trusted advisor who can be counted on both professionally and personally, as his commitment inside the courtroom is mirrored in his community. He has taught at Queen’s University Faculty of Law, the University of Windsor Faculty of Law and McMaster University’s DeGroote School of Business, and regularly speaks and leads seminars at The Advocates’ Society, Osgoode Hall Law School, the Law Society of Ontario, the Law Society of Prince Edward Island, and the Canadian Bar Association in Ontario and Prince Edward Island. He is a member of the LSPEI’s Continuing Professional Education Sub-Committee.

Tom has served as board director for several charitable groups, drawing on his legal expertise by leading special committees related to corporate governance and re-organization. Tom also served on the firm’s Board of Partners between 2018 and 2020.
