On October 7, 2011, the Ontario Securities Commission (“OSC”) published a Notice and Request for Comment (the “Notice”) on the Application by Maple Group Acquisition Corporation (“Maple”), a consortium of Canadian investment dealers, pension funds and other institutional investors, to acquire TMX Group Inc., Alpha Trading Systems Limited Partnership, Alpha Trading Systems Inc., the Canadian Depository for Securities Limited and, indirectly, CDS Clearing and Depository Services Inc. Maple is proposing to create an integrated group of businesses that provide trading, clearing, settlement and depository services for a broad array of financial instruments. The Alberta and B.C. Securities Commissions have also published a Joint Notice and Request for Comment seeking input on the Application.

The Notice summarizes the Maple proposal, highlights key issues that may arise from the proposed acquisition and provides information about the comment process.

The comment period is open until November 7, 2011. The OSC intends to hold a policy hearing in December 2011 to give members of the public who have submitted written comments an opportunity to clarify or expand on their written submissions.
