Justin Nasseri

Justin Nasseri is one of the founding partners of Ross Nasseri LLP. He is an experienced trial and appellate lawyer with a significant track record of success in complex commercial, regulatory, and professional liability matters. He is also a go-to litigator for civil or regulatory proceedings where there is a parallel criminal law component.

Clients trust Justin’s advice because of his breadth of experience and battle-tested instincts and judgment. He has appeared as counsel before all levels of court in Ontario, numerous arbitral panels, and administrative tribunals including the Financial Services Tribunal, the Health Professions Appeal and Review Board, and the Discipline Committees of the College of Physicians and Surgeons of Ontario and the College of Naturopaths of Ontario.

Justin has received national recognition for his accomplishments as an advocate, including being recognized as a Litigation Star and Canada’s 2022 Emerging Talent Litigator of the Year by Benchmark Litigation, a Lexpert Rising Star – Leading Lawyer Under 40 and a leading litigator with the designation of Consistently Recommended in Corporate Commercial Litigation by Lexpert in 2022, and a leading commercial litigator by Best Lawyers in 2023.

According to leading industry publications, anonymous client and peer reviews describe Justin as “an exceptional advocate”, a “one in a million type of lawyer,” someone for whom “any client would be lucky to have in their corner”, “a natural advocate with an instinct for identifying and preparing winning arguments, and deep experience in appellate advocacy….”. According to one anonymous peer review: “In my 14 years of Bay Street practice, his was one of the best advocacy performances I have seen.”

Justin’s recent wins include overturning an unprecedented $9M judgment as a sanction for contempt at the Court of Appeal for Ontario, winning a significant commercial property trial over the sale of a religious institution, resisting the appeal of a jury verdict in a significant medical malpractice case, and successfully representing PEN Canada in a constitutional challenge to an overly broad ‘false statements’ prohibition in Canada’s federal election legislation.

Justin is also widely published on litigation topics including contract law, civil and criminal procedure, and injunctive relief. His publication history includes works in the Annual Review of Civil Litigation, the Alberta Law Review, the Canadian Privacy Law Review, and the Advocates’ Society. Justin is also frequently asked to speak at and write for legal education conferences hosted by the Law Society of Ontario, the Ontario Bar Association, and the Advocates’ Society.

Justin is also a past Chair of the Executive Committee of the Ontario Bar Association’s Civil Litigation section, where he organized legal education programs and was involved in advocating for policy reforms that included increased adoption of technology and removing the need for pregnant counsel to wear robes in court.

Before co-founding Ross Nasseri LLP, Justin trained with leading litigation firms McCarthy Tétrault and Pape Barristers (now Pape Chaudhury LLP). He received his JD from the University of Toronto, and a B.A. in Economics and Political Science with First Class Honours from the University of Alberta.
