Background, Outline and Rationale for the Amendments

Contingent Option Trades play a pivotal role in the strategic operations of many market participants. A "Contingent Option Trade" is the trade of securities on TSX (that are underlying an option traded on MX) that are effected as part of a pre-existing MX Trade (as defined below).

Currently, Contingent Option Trades are resource intensive and a manual process for both TMX staff and MX clients. To effect a Contingent Option Trade, an MX client ("Client A") is required to contact a market supervisor of MX and indicate that they wish to effect a trade of the option as a cross. Pursuant to the applicable MX rules, 50% of the volume (the "50% MX Rule") must be made available to qualified market makers on MX before a cross can be effected. The market supervisor of MX will telephone the qualified market makers to "shop around" the trade. If there are no interested parties, then Client A can complete the full volume of the option cross trade. If the MX market supervisor finds an interested MX market maker ("Client B"), then Client B will be the opposite side of the option trade. When a match is found (whether with Client B or the full cross for Client A), a timestamp is created for that match (the "MX Trade"). The MX market supervisor then contacts TSX staff (via email and telephone) to advise and provide details of the MX Trade including the timestamp. TSX staff will then manually effect the trade of the underlying equities securities on TSX at the timestamp between Client A and Client B (or in the case of a full cross, just Client A). Client A and Client B are always approved participants of MX and TSX. Under the current procedures, a Contingent Option Trade must occur within the existing market price (the "NBBO") for the underlying security at the timestamp.

Given that price discovery occurs on MX and the relative price of the options instrument to the underlying securities is what drives trading on Contingent Option Trades, TSX is proposing to amend the Contingent Option Trade procedures to allow for the trade in securities on TSX to execute at a price within the daily high and low price, which may be outside the NBBO (the "COT Amendments"). Contingent Option Trades will continue not setting the last sale, open, close, high or low prices, and will be disseminated using the existing "MS" special terms marker on the TSX public market data feeds. The COT Amendments seek to provide TSX participants and MX members with the flexibility and confidence to effect both the equity and derivative components of a Contingent Option Trade with ease. The COT Amendments are a result of client demand and aim to align our Contingent Option Procedures with other markets who offer this functionality as described in the MX proposal found here.

The scenario below illustrates how a Contingent Option Trade would be treated under the current procedures and under the Amendments:

• A dealer creates the following contingent option instrument on MX:

• Expiry date: June 1, 2024

• Strike Price: $43.00

• Call option

• Underlying Equities Price: $42.20

• Delta: 45%

• If the option quantity traded is 200 call option contracts, the underlying equities trade that would be routed to TSX is 9,000 shares at $42.20 per share calculated as follows:

• 200 options x 100 (option multiplier) x 45% (delta) = 9,000 shares at $42.20 per share.

In this scenario, if the NBBO was $42.00 at the time of the trade, the equities portion would not trade under the current procedures as the price for the underlying equities security is outside of the NBBO. However pursuant to the COT Amendments, the underlying equities securities would now trade even though the price is outside of the NBBO.

In connection with COT Amendments, TSX is also proposing to automate the process for Contingent Option Trades (the "Automation Amendments", and together with the COT Amendments, the "Amendments").

While Rule 4-1103 -- Exchange for Physicals and Contingent Option Trades of the TSX Rules ("Rule 4-1103") permits the Amendments, TSX is proposing that the policies and procedures as set out in Policy 4-1103 Exchange for Physicals and Contingent Option Trades be removed from the TSX Rules. TSX is of the view that these policies and procedures are not required to be reflected in the TSX Rules. The applicable policies and procedures will be communicated to participants from time to time, and can be found in the Order Types and Functionality Guide.

Blackline of Amendments

A blackline of the Amendments against the existing rules is attached as Appendix A hereto for ease of reference.

Analysis of Impacts

(i) Impact on Market

TSX anticipates that the Amendments will have a positive impact on the market structure, members, investors, issuers or the capital markets. As noted above, the Amendments will provide MX clients, and ultimately TSX clients, with the flexibility and confidence to effect both the MX Trade and Contingent Option Trade.

TSX believes that the Amendments are fair and reasonable, and will not create barriers to access.

For the reasons mentioned above, TSX is of the view that the Amendments are not contrary to the public interest. While the Contingent Option Trades may be within the TSX's daily high and low price, the parties to the trade are the same parties to the MX Trade who have made informed decisions in respect of both the MX Trade and the Contingent Option Trade. In addition, Contingent Option Trades do not set the "last sale" price for securities on TSX.

(ii) Impact on Members and Service Vendors

The Amendments are expected to have a positive impact on members.

TSX does not require any systems change for TSX clients. However, we understand that the changes proposed by MX will require significant systems changes for MX members.

In order to ensure client readiness and a seamless transition with no impact on the market, even after the Amendments are implemented, TSX anticipates that there will be a six-month period by which Contingent Option Trades could be effected manually in the same manner as they are today. TSX staff will support this transition period by manually handling any of the trades until the transition period is completed. There are no changes required by TSX clients.

Under the automated process, Contingent Option Trades will continue to be marked as "MS".

(iii) Impact on Compliance with Applicable Securities Laws

The Amendments will not impact TSX's compliance with applicable securities laws requirements for fair access and maintenance of fair and orderly markets. As noted above, TSX is of the view that the Amendments will support the maintenance of fair and orderly markets.

Consultations Undertaken in Formulating the Amendments

TSX did not conduct any consultations in regards to the Amendments.

However, TSX understands that MX consulted its members regarding its proposed amendments, which included automating Contingent Option Trades.

Alternatives Considered

No alternatives were considered.

Timing

Following receipt of regulatory approval, TSX intends to implement the Amendments in Q2 2024, subject to MX members having made the necessary changes to take into account the Amendments.
