TMX Operational Notice

Update: Changes to the Settlement Cycle (T+1)

Further to Equities Trading Notice 2023-045, TMX Equities is reminding Participants that the settlement cycles in the Canadian and U.S. securities industries are being shortened from trade date plus two business days ("T+2") to trade date plus one business day ("T+1"). The first day of T+1 trading in the Canadian securities industry will be Monday, May 27, 2024. Since Monday, May 27, 2024, is a U.S. Holiday, the change to the settlement cycle in the U.S. securities industry is expected to be effective Tuesday, May 28, 2024.

Amendments to each of the Toronto Stock Exchange ("TSX") and TSX Venture Exchange ("TSXV") Rule Books related to the T+1 settlement cycle will become effective May 27, 2024. The Notice of Housekeeping Rule Amendments for each TSX and TSXV can be found here.

Special Settlement Terms for Cash Next Day Delivery

As a result of T+1 becoming regular settlement, orders and crosses submitted with special settlement terms for cash next day delivery will be rejected effective May 27, 2024.

Future Behaviour





Participants are advised to monitor any open GTC or GTD orders marked with special settlement terms for cash next day delivery.

This behavior will be available in our GTE environment effective March 26, 2024 and updated specifications are available on the TMX Webstore.

T+1 Migration Record and Ex-Dates

The change to a T+1 settlement cycle results in ex-dates for dividends, distributions, and other corporate actions changing from one business day before the record date to the day of the record date. As a result of the transition from T+2 to T+1, no listed security will commence ex-dividend trading on Monday, May 27, 2024. The chart below provides examples of the ex-dates under the T+1 settlement cycle:
