Gerald Chan

Practice Areas

Described as a “superstar” (Benchmark Litigation), Gerald practices criminal, constitutional, administrative, and select civil/commercial litigation. He has been recognized as a leading practitioner by Best Lawyers in Canada, Benchmark Litigation, Chambers Canada, and Lexpert. In 2019, Canadian Lawyer named Gerald one of the Top 25 Most Influential lawyers in Canada.

Gerald defends clients facing all manner of charges, including white collar crime, cyber crimes, sexual offences, and quasi-criminal / regulatory matters — especially those involving digital evidence and technology-related issues. He frequently advises clients at the investigation stage, where he has dealt with the OSC Joint Serious Offences Team, RCMP Integrated Markets Enforcement Team, OPP, Canada Border Services Agency, Canadian Food Inspection Agency, and the Ministry of Labour. His cases in this area often involve parallel civil proceedings, such as interlocutory injunction applications, civil fraud claims (Mareva injunctions and Anton Piller orders) and class actions.

Gerald frequently represents clients on appeals and judicial reviews. He has argued before every level of court, including over 20 cases in the Supreme Court of Canada (privacy, foreign corruption, insider trading, and medical marihuana), the Court of Appeal for Ontario (where he frequently appears as a member of the Ontario Inmate Appeal Duty Counsel Program), and Divisional Court.

Gerald has particular expertise in data privacy matters. He has been involved in many of the leading Supreme Court of Canada cases on the issue, including R v Marakah, R v Jones, R v Mills, R v Fearon, R v Vu, and R v Cole.

Gerald also frequently acts for lawyers and law firms. He has defended lawyers in negligence claims, advised them on privacy breaches, represented their interests in ineffective assistance of counsel appeals, and defended them against conflict of interest allegations. He has also acted for lawyers facing discipline by the Law Society and subpoenas to testify in court.

Apart from his practice, Gerald is a prolific writer and teacher. He is co-author of the 8th and 9th editions of Sentencing (LexisNexis); co-author of Digital Evidence: A Practitioner’s Handbook (Emond Publishing); co-editor of Digital Privacy: Criminal, Civil and Regulatory Litigation (LexisNexis); and co-editor of Litigating Artificial Intelligence (Emond Publishing). He teaches on the faculty of the Federation of Law Societies of Canada’s National Criminal Law Program and the adjunct faculty of the University of Toronto, Faculty of Law (Criminal Procedure and the Criminal Appellate Externship).

Gerald is a member of the Judicial Appointments Advisory Committee (appointed by the Law Society of Ontario), and Case Review Committee of Innocence Canada. He is also the immediate past president of the Federation of Asian Canadian Lawyers (Ontario).

Before joining Stockwoods, Gerald was a partner with Clayton Ruby at a leading criminal and constitutional law firm. Before that, Gerald practiced commercial litigation with a large firm and clerked for Justice Abella at the Supreme Court of Canada. He graduated as co-Gold Medallist from Osgoode Hall Law School.
