Reminder - TSX/TSXV Closing Price, Last Ask Price and Last Bid Price Implementation

TMX Equities Trading is reminding all clients that effective September, 27th, 2021, the approved changes to the TSX/TSXV Closing Price, TSX/TSXV Last Ask Price, and TSX/TSXV Last Bid Price will be implemented in our production environment.

In summary, the TL1 and TRD values will be renamed to "TSX Closing Price", "TSX Last Ask Price", and "TSX Last Bid Price". CL1 and VRD values will be renamed to "TSXV Closing Price", "TSXV Last Ask Price", and "TSXV Last Bid Price". The messages will be sent out twice daily at 4:10pm and 5:00pm ET. The latter time will capture any trade cancellations that may affect the TSX Closing Price or TSXV Closing Price values.

Additional information can be found in Equities Trading Notices 2021-014 and 2021-013

This message type will not impact, nor will it replace, the official last sale price for the purposes of Last Sale Trading Session or determining the following day's board lot size.
