About O'Toole Advocacy

O'Toole Advocacy is a small Toronto business litigation firm. It's the registered business name of Bruce O'Toole Law Professional Corporation, run out of an office suite at 10 King Street East in the city's Financial District. The practice centres on commercial and securities litigation, including class actions and regulatory proceedings, and it also takes on general corporate and shareholder disputes, directors' and officers' liability matters, mining disputes, contractual and negligence claims, investment loss claims, employment disputes, and administrative law.

Bruce O'Toole has appeared before the Commercial Court and the Court of Appeal for Ontario, and has represented clients in investigations and enforcement hearings before regulators including the Ontario Securities Commission, the Canadian Investment Regulatory Organization, the Investment Industry Regulatory Organization of Canada, and the Mutual Fund Dealers Association. Beyond litigation, O'Toole also works as a mediator, helping parties move past fixed positions toward practical, value creating solutions instead of getting stuck arguing over positions. The firm bills on a flat fee or hourly basis and describes its rates as typically one half to two thirds of what large commercial firms charge.

The neighbourhood

The firm's office sits in a fifteen storey building at 10 King Street East, put up in 1960 in Toronto's Financial District. The TTC streetcar runs right at the building's front door and the subway is only steps away, which is useful for a practice built around commercial and securities litigation: the regulators and courts at the centre of that work sit in the same downtown core. It's a working office tower rather than a landmark, but the location keeps the firm inside the same few blocks as the institutions its cases usually involve.
