Derek Abreu articled with Bell Temple, and was admitted into the firm’s Partnership in 2010. He is a strong and fearless advocate in the courtroom, who has been involved in arguing some of the leading cases affecting the insurance industry. As counsel in over 40 reported decisions, Derek has represented his clients successfully at all levels of court in Ontario, including the Superior Court of Justice, Divisional Court, Court of Appeal for Ontario, as well as written Responses to Leave Applications to the Supreme Court of Canada. Notably, Derek was retained by the Canadian Defence Lawyers to intervene at the Court of Appeal in Martin v. Fleming & Campoverde, and was successful in having the plaintiffs’ appeal dismissed and to thereby confirm that multiple deductibles do apply in actions involving multiple motor vehicle accidents (read article in OBA Insurance Law Section Newsletter – February 2013). He is also Co-Chair of the firm’s Appellate Advocacy Group.

Derek approaches litigation with the philosophy that “every case is different and therefore requires a unique and tailored approach”. His practice includes a special focus on claims involving tort motor vehicle accidents, UMC and 44R claims, occupiers’ liability, restaurant/tavern liability, coverage disputes, duty to defend/indemnify Applications, and Appeals. He is preferred counsel for some of Canada’s largest automobile/commercial general liability insurers, real estate/property landlords, and restaurant/bar chains.

Starting in 2018, Derek has also been offering his services as a Mediator in a variety of personal injury, occupiers’ liability, subrogation, motor vehicle, property and commercial litigation matters. He is widely respected for his knowledge and experience in the courtroom, which he uses to help litigants identify common goals, consider novel solutions, and facilitate compromises in even the most complex, multi-party disputes. Derek can be booked as a Mediator through his assistant, Barbara Tobias: 416-581-8200; ext. 6236 btobias@belltemple.com (click to see On-line Calendar; Fee Schedule; and Mediation Agreement).
