Litigation Star



Justin Nasseri is an experienced trial and appeal lawyer and a co-founder of Ross Nasseri LLP. He has 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 several Ontario health colleges.

Justin’s wins include resisting an urgent Norwich motion for which he secured substantial indemnity costs in favour of his client, and resisted a leave to appeal motion at the Divi-sional Court, 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. He is 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.
