The appellant, a former member of the Investment Dealers Association (IDA), challenged the IDA's jurisdiction to discipline him after he ceased to be a member.
The IDA's by-laws permitted discipline of former members for up to five years, and the Ontario Securities Commission upheld this jurisdiction.
On appeal, the Divisional Court applied a reasonableness standard of review and found that the Securities Act only authorizes the regulation of current members.
The court concluded that the IDA's by-law contravened the Act and that the IDA lacked jurisdiction to discipline former members.
The appeal was allowed.
