Thomas McCann is a criminal trial and appeal lawyer at Daniel Brown Law. He is sensitive to the harm that accompanies being charged and thrust into the criminal justice system, and he is tenacious in advancing his clients’ best interests in a timely and strategic manner. Thomas makes sure his clients are thoroughly informed and guided through a process that can be highly stressful and overwhelming, particularly for those with no prior involvement in the criminal justice system.

Courtroom experience

Thomas brings a perspective few defence lawyers have: he served as an Assistant Crown Attorney, prosecuting serious drug and organized crime cases, and also has a background in civil law. His litigation experience is extensive in both the Ontario Court of Justice and the Superior Court of Justice, including jury trials, preliminary inquiries, constitutional challenges, and bail hearings. He also acts as appeal counsel.
