About Graham Zoppi Criminal Lawyer

Graham Zoppi Criminal Lawyer, also known as RGZ Law, is a criminal defence firm with its main office at Bay and Queen streets in downtown Toronto. The firm is built around Graham Zoppi, who has practised criminal law for more than 20 years and has run an independent criminal defence practice for more than a decade. Before opening that practice, Zoppi articled with judges of the Superior Court of Ontario and served as Crown Counsel with the Ministry of the Attorney General, arguing appeals at the Ontario Court of Appeal and handling bail hearings and trials in the Ontario Court of Justice. Zoppi also worked in the litigation group at Blake, Cassels & Graydon, on civil litigation, criminal matters, and Ontario Securities Commission cases.

The firm's second lawyer, Hillson Tse, handles cases in Cantonese and works with interpreters for Mandarin speaking clients. Tse's earlier work included assisting the United Nations in Beijing on rule of law and governance projects, and heading a student rights advocacy office that represented students in academic misconduct proceedings, a practice area the firm still handles today alongside its core criminal defence work in impaired driving, assault, drug and firearms charges, fraud, and bail hearings. Along with its Toronto office, the firm lists contact locations in Scarborough and Brampton and takes on cases across Ontario.
