Notice of Approval - Amendments to TSX Rule Book - Market on Close facility - Toronto Stock Exchange (TSX Inc.)

Introduction

In accordance with the Process for the Review and Approval of Rules and the Information Contained in Form 21-101F1 (the "Protocol"), TSX Inc. ("TSX") has adopted, and the Ontario Securities Commission (OSC) has approved, amendments (the "Amendments") to the TSX Rule Book (the "Rules") to reflect enhancements to the Market on Close ("MOC") facility operated by TSX. The Amendments are public interest amendments to the Rules. The Amendments were published for public comment in a request for comments on June 30, 2016 (the "Request for Comments").

Reasons for the Amendments

The Amendments are being made to reflect the following changes:

1. A second MOC imbalance will be calculated and broadcast in the event of a delay of the closing call due to the invocation of the price movement extension ("PME").

2. Following the broadcast of the second MOC imbalance, MOC limit orders may be entered in the MOC book on the opposite side of the second MOC imbalance.

3. MOC limit orders that are not included in the first or second MOC imbalance may be cancelled subject to the time constraints set by TSX.

The Amendments were developed in consultation with the MOC user community to address certain functionality deficiencies related to the PME. The Amendments will improve the ability of participants to offset MOC imbalances during a PME session. This will, in turn, help reduce the price volatility of MOC securities in closing calls that are delayed due to a PME. In addition, permitting participants to cancel MOC limit orders submitted during the PME will make the MOC facility functionality consistent as between the 3:40 to 4:00 p.m. time period (the "MOC imbalance market state") and the PME session.

Summary of Comments and Text of the Final Amendments

No comment letters in response to the Request for Comments were received and no changes have been made with respect to the Amendments outlined in the Request for Comments.

The Amendments will be finalized in the form attached as Appendix A.

Effective Date

To be determined.
