The appellants appealed a decision of the Ontario Securities Commission (OSC) that upheld the Investment Dealers Association of Canada's (IDA) disciplinary actions against them.
The IDA had fined the appellants and terminated their membership for failing to provide documents during an investigation into alleged principal trading in an error account.
The appellants argued the IDA lacked jurisdiction, its by-laws violated the Charter, and the investigation was unreasonable.
The Divisional Court applied a reasonableness standard of review and dismissed the appeal, finding the IDA is not a government entity subject to the Charter, its investigative powers are valid under the regulatory scheme, and its disciplinary process and penalties were reasonable.
