TSX INC. (TSX)

AMENDMENTS TO THE RULES OF THE TORONTO STOCK EXCHANGE
TO ALLOW NON-DISPLAYED ORDERS OF A MINIMUM QUANTITY
TO HAVE TRADING PRIORITY OVER OTHER NON-DISPLAYED ORDERS

NOTICE OF COMMISSION APPROVAL



On December 2, 2011, the Ontario Securities Commission approved amendments to Rules 1-101, 4-801 and 4-802 of the TSX to allow non-displayed orders (Dark Orders) of a certain size determined by the TSX (Minimum Quantity) to have trading priority over other Dark Orders without such a condition, provided the Dark Orders are at the same price. The amendments also introduce a definition of a Minimum Quantity.

The amendments were published for comment on July 8, 2011 for a 30 day comment period. No comments were received. Subsequent to their publication, the TSX made a non-material amendment to the definition of Minimum Quantity to clarify that it is the minimum size for the execution of an order. The TSX also made a consequential amendment to subsection (3) of TSX Rule 4-802 to clarify that the allocation of trades is subject to the priority of Dark Orders marked with a Minimum Quantity. The rule amendments blacklined to show the changes, are also published.
