When police and other first responders are in trouble, they turn to Eugene Mazzuca. For more than 15 years, Eugene has been the first contact for provincial and municipal entities and their insurers accused of false arrest, excessive force, malicious prosecution, negligent investigation, defamation, personal injury, property damage and other serious torts. He also handles claims against security guards as well as roads liability cases and unusual and novel claims for municipal and provincial bodies.

Special Care for Sensitive Cases

Eugene’s discretion and practical advice are exceptional. Knowing that the most successful cases are often those that are resolved quickly, he conducts a thorough early-stage assessment of each matter to determine its merits and develop exit strategies. In addition, Eugene meets with clients to conduct preventative training and advise on specific issues and practices.

A Force in the Courtroom

He is known for his ability to engage juries and elicit case-winning testimony. Eugene also excels at managing situations involving proceedings in multiple venues. A familiar and respected face in the courtroom, Eugene is uniquely experienced in handling both trials and appeals at every level of the Canadian legal system, including the Supreme Court of Canada.

Eugene has defended hundreds of claims against government entities including the Ontario Provincial Police, the Peel, Niagara, York and Durham Regional Police, and the Ontario Ministry of Transportation, Natural Resources, Health, Environment and Public Safety.
