Chad M. Leddy


Chad Leddy is a tenacious litigator with a diverse civil defence practice. He has extensive experience defending product liability, construction liability, occupiers’ liability, and motor vehicle claims. He also has experience providing coverage opinions and defending first party claims against insurers.

Chad focuses on exceeding client expectations, always bearing in mind that different clients have different litigation strategies and goals. He has used a firm but principled approach to defending cases to secure the outright dismissal of all claims against his clients without any payment in more than 75 cases, either via summary judgment (or other) motions or at trial, or by prompting plaintiffs to just give up and walk away from meritless claims at mediation or otherwise. At the same time, Chad is pleased to negotiate settlements on fair terms where possible, and has negotiated settlements of over 250 claims, at mediations, pre-trials, or if sensible at a lawsuit’s early stages.

Chad has appeared at all levels of court in Ontario, including the Small Claims Court, Superior Court, Divisional Court, and the Court of Appeal. He has appeared as co-counsel in a jury trial and appeared as lead counsel in a number of summary judgment motions and appeals.

Chad is chair of Dutton Brock’s professional education committee and a member of its articling committee, and takes pride in mentoring younger lawyers. He is a member of various professional associations and regularly speaks and presents to clients and colleagues in the insurance industry. Less seriously, Chad is proud to have been a member of a past winning team - “Torts Illustrated” - at the Advocates’ Society lawyers’ trivia challenge.

Outside of work, Chad enjoys spending time with his wife and negotiating with his three young children, all stubborn advocates.

Chad studied law at the University of Toronto, where he was a member of the Canadian champion team at the prestigious Philip C. Jessup Mooting Competition. He represented Canada at the international rounds of that competition in Washington, leading his team to the knock-out rounds.
