About Joseph Castaldo

Joseph Castaldo Professional Corporation is a solo criminal defence practice based in Toronto, Ontario. The firm's lawyer, Joseph Castaldo, was called to the Ontario Bar and joined the Law Society of Upper Canada in 1988, after earning a Combined Honours Bachelor of Arts in Economics and Sociology from York University in 1983 and a law degree from the University of Windsor Law School in 1986. The office is in the Centre Tower of Bloor Islington Place on Bloor Street West in Toronto.

The practice covers Criminal Code offences and provincial regulatory charges, including fraud and theft, domestic and sexual assault, impaired and dangerous driving, weapons and firearms offences, drug charges under the Controlled Drugs and Substances Act, youth criminal justice matters, and Ministry of Environment and Ministry of Labour regulatory offences. Castaldo has appeared at every level of Ontario's criminal courts on behalf of individuals and corporations and has represented other lawyers before the Law Society of Upper Canada's disciplinary panel. From 1999 to 2005, Castaldo served as a seminar instructor in Criminal Law, Procedure, Ethics and Professional Responsibility at the Law Society's bar admissions course, and continues to mentor newly called criminal defence lawyers.

The neighbourhood

The office is in the Centre Tower of Bloor Islington Place, a Class A office complex at Bloor Street West and Islington Avenue, built in 1981. The complex connects directly to Islington subway station and the Islington GO bus terminal, with quick access to the 400 series highways. That kind of access suits a practice that, by its own description, is based in Toronto but takes on cases throughout the province of Ontario rather than staying within one district.
