Notice of Housekeeping Rule Amendments - Housekeeping Amendments to the Rules of the 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 has approved, amendments (the "Amendments") to the TSX Rule Book. The Amendments are Housekeeping Rules under the Protocol and therefore have not been published for comment. The Ontario Securities Commission has not disagreed with the categorization of the Amendments as Housekeeping Rules.

Reasons for the Amendments

Rule 4-305 Sales from Control Block Through the Facilities of the Exchange has been amended to conform to Part VI, Section M of the TSX Company Manual (the "Manual").

Rule 4-305 of the TSX Rules and Part VI, Section M of the Manual are intended to be consistent with each other and National Instrument 45-102 -- Resale of Securities ("NI 45-102"). When Part VI, Section M of the Manual was amended Rule 4-305 was inadvertently not amended, resulting in an inconsistency. Rule 4-305 is therefore out of date and has been amended to conform to Part VI, Section M of the Manual and NI 45-102.

Text of the Amendments

The Amendments to the TSX Rule Book are set out as blacklined text at Appendix A.

Timing

The Amendments become effective today, April 6, 2017.
