OSC Implements New Process Aligning the Transparency of Changes to the Operations of
Stock Exchanges and Alternative Trading Systems


TORONTO – The Ontario Securities Commission (OSC) today announced the implementation of a new process to align the transparency of changes for the operations of recognized stock exchanges (Exchanges) and Alternative Trading Systems (ATS) where their operations are similar.

“This new process recognizes the need for a similar degree of transparency for Exchanges and ATSs in certain areas,” said Susan Greenglass, Director of Market Regulation at the OSC.

Effective October 9, 2009, both Exchanges and ATSs will publish notice of certain proposed changes to their operations. There is no change to the current filing requirements for Exchanges and ATSs.

The process, described in OSC Staff Notice 21-703, will apply to new order types, changes to existing order types, and to other issues relating to trading such as procedures governing the entry and display of orders on marketplace systems.

OSC Staff Notice 21-703 Transparency of the Operations of Stock Exchanges and Alternative Trading Systems is available in the Securities Law & Instruments section of the OSC website, www.osc.gov.on.ca.
