Stephanie DiGiuseppe’s practice focuses on criminal and constitutional litigation. She also represents clients in quasi-criminal matters, professional disciplinary hearings, and select civil matters. Stephanie DiGiuseppe is a skilled and passionate advocate for her clients. She brings energy and creativity to her practice, fearlessly advancing novel legal and Charter-based arguments to better defend her clients.

Stephanie received her J.D. degree from Osgoode Hall Law School and her B.A. from McGill University.
Stephanie practices at all levels of Court in Ontario, including frequently appearing before the Ontario Superior Court of Justice and Ontario Court of Appeal. In addition, she has represented clients in written arguments before the Supreme Court of Canada.
Stephanie regularly represents individuals facing serious criminal charges, including homicide, charges stemming from large-scale narcotics and firearms investigations (“Projects”), domestic assault, and sexual assault. She specializes in the litigation of complex cases and constitutional challenges, such as challenges to legislation, search warrants, and wiretaps.

Stephanie has been counsel or co-counsel on a number of high profile cases. During her articles and first year of practice, she was a member of the defence team representing Michael Rafferty, charged with the 2009 abduction and murder of Tori Stafford, one of the most vigorously prosecuted cases in Ontario’s history. She has represented clients at the trial and appellate level in a number of highly publicized homicides, including the 2012 shooting at the Toronto Eaton Centre, and has been representative counsel challenging the constitutionality of a number of prominent wiretap investigations, including Project Traveller (the wiretap investigation which led to the discovery of the Rob Ford tapes).

However, Stephanie understands that any interaction with the criminal justice system has the potential to change the course of an individual’s life, and she brings the same vigour and creative approach to every case, regardless of the charge.

Stephanie is actively involved in the legal community. She is a member of the Advocate’s Society, the Criminal Lawyers’ Association, and the Toronto Lawyer’s Association. She sits on the Criminal Lawyers’ Association Communications and Media Relations Committee.

Stephanie also dedicates her time and efforts to a number of social justice initiatives. She is passionate about her work with Peacebuilders International, an organization that provides restorative justice programs for youth who have come into contact with the criminal justice system, the Campaign for Cannabis Amnesty, a group she helped to found, which is involved in lobbying the federal government to grant automatic pardons to individuals with criminal records for offences relating to personal possession of cannabis, and with prison reform initiatives, such as the Campaign for the Abolition of Solitary Confinement.
