The Bourse de Montreal Inc., the operator of the Montreal Exchange, is seeking to amend its rules to ensure that it retains jurisdiction for three years over traders that leave the industry.

The special committee of the regulatory division of the Bourse has approved a rule change that aims to clarify the extent of its jurisdiction over traders who are no longer in the industry, but are subject to an investigation. It would specify that the Bourse retains jurisdiction for 36 months after termination of a traders’ approval.

The amendment comes on the heels of a disciplinary decision rendered earlier this year in which it was determined that the Bourse didn’t have jurisdiction to discipline a former trader for failing to cooperate with an investigation after he left the industry.

The Bourse says that the amendment will ensure the co-operation of those who leave the industry with any investigation carried out in the period. It says that the rule is in the public interest, and the industry’s interest.
