PROFESSIONAL HIGHLIGHTS
A Lawyer who Listens
Justin Martin is a Toronto-based partner at Lerners whose litigation practice focuses on health law and insurance defence.
“I assist health professionals — primarily physicians — in litigation and regulatory proceedings, be they lawsuits, complaints, or investigations,” explains Justin. “I also advise on issues relating to patient management and privacy concerns.
“In my specialty risk and insurance practice, I defend insured entities, including municipalities, police services, children’s aid societies, and individuals on a wide range of matters. This includes actions relating to personal injury, motor vehicle accidents, occupier liability, slip and falls, and property damage.”
Justin has appeared before the Ontario Superior Court of Justice, the Divisional Court of Ontario, Small Claims Court, and the Health Professions Appeal and Review Board. He has also acted on matters before the Ontario Court of Appeal; the Workplace Safety and Insurance Appeals Tribunal; the Ontario Land Tribunal; and the College of Physicians and Surgeons of Ontario’s Inquiries, Complaints and Reports Committee.
Representing several police services, Justin acts for police officers in malicious prosecution and negligent investigation proceedings. He also defends municipalities in matters relating to issues such as the design of highways and roads, building inspection and acts for municipal employees who are targeted for the execution of their duties.
He is a reasonable and even-keeled lawyer that has empathy for his clients. “I understand how stressed they are dealing with litigation or regulatory complaints,” says Justin.
A hardworking but reasonable advocate, Justin will defend his client’s interests to the best of his ability. However, he also considers himself a collaborative lawyer, and he will consider his client’s input carefully when strategizing. “I will always be a strong advocate for my clients. However, I also believe it is important to be frank and candid with my clients. If we have serious issues with our case, my client needs to know and consider this when giving instructions.”
