About Roy O'Connor LLP

Roy O'Connor LLP is a small litigation firm in Toronto that focuses on class actions, commercial and securities litigation, and general civil litigation. Founding partners Peter L. Roy and David F. O'Connor left large national law firms to start the practice, bringing decades of complex corporate commercial and securities litigation experience with them. The firm represents both plaintiffs and defendants, appearing before Canadian courts and administrative tribunals in disputes involving securities regulation, shareholder rights, and director and officer liability.

As class counsel, the firm has secured judgments and settlements exceeding $2.5 billion, including work on the national hepatitis C settlement for people infected through blood transfusions before 1986 or after 1990, and unpaid overtime claims against several Canadian banks. Roy is a Certified Specialist in Civil Litigation with the Law Society of Upper Canada and a Fellow of the Litigation Counsel of America. O'Connor served on the steering committee for the Volkswagen and Audi diesel emissions class actions, which reached settlements exceeding $2.3 billion. Robert Spiegel, Of Counsel to the firm, practices in English and French after seven years as counsel at the Toronto Stock Exchange.
