Notice of Housekeeping Amendment to the Toronto Stock Exchange Rule Book – 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, an amendment (the "Amendment") to the Toronto Stock Exchange Rule Book (the "TSX Rulebook"). The Amendment is a Housekeeping Rule under the Protocol and therefore has not been published for comment. The Ontario Securities Commission has not disagreed with the categorization of the Amendment as a Housekeeping Rule.

Reasons for the Amendment

The Amendment is being made to the TSX Rulebook to permit trades in a Special Trading Session (as defined in the TSX Rulebook) where the Last Sale Price (as defined in the TSX Rulebook) is not a valid price increment.

Summary of the Amendment

Currently, any orders where the Last Sale Price is outside of a permitted price increment cannot be entered into the Special Trading Session. The Amendment will allow for otherwise invalid orders by allowing orders to be entered at the Last Sale Price rounded up to the nearest price increment, and would enable market participants to continue executing transactions in the Special Trading Session.

Text of the Amendment

The Amendment is set out as blacklined text at Appendix A.

Timing

The Amendment will become effective July 13, 2020.
