    4. has a value of $250,000 or more
      if the entry of the order on a foreign organized regulated market would avoid execution against a better-priced order entered on a marketplace pursuant to Part 6 of the Trading Rules.

POLICY 6.4 – TRADES TO BE ON A MARKETPLACE

Part 1 – Trades Outside of Marketplace Hours

In accordance with section 6.1 of the Trading Rules, each marketplace shall set requirements in respect of the hours of trading to be observed by marketplace participants. Occasions may arise when a Participant may wish to make an agreement to trade as principal with a Canadian account, or to arrange a trade between a Canadian account and a non-Canadian account, outside of the trading hours of any marketplace that trades the particular security.

Rule 6.4 states that all trades must be executed on a marketplace unless otherwise exempted from this requirement. Participants are reminded of the exemption in clause (2)(d) of Rule 6.4 that permits a trade on a foreign organized regulated market. Participants are also reminded of the exemption in clause (2)(e) of Rule 6.4 that permits them to trade as principal with non-Canadian accounts off of a marketplace provided that any unwinding trade with a Canadian account is made in accordance with Rule 6.4.

A Participant may make an agreement to trade in a listed security or a quoted security with a Canadian account as principal or as agent outside of the trading hours of marketplaces, however, such agreements must be made conditional on execution of the trade on a marketplace or on a foreign organized regulated market. There is no trade until such time as there is an execution on a marketplace or a foreign organized regulated market or the trade is otherwise completed in accordance with one of the exemptions set out in Rule 6.4. The trade on a marketplace is to be done at or immediately following the opening of the marketplace on which the order is entered. A Participant may cross the trade at the agreed-upon price provided that the normal Requirements on order displacement are followed. If the Participant determines that the condition of recording the agreement to trade on a marketplace or foreign organized regulated market cannot be met, the agreement to trade shall be cancelled. Use of an error account to preserve the transaction is prohibited.

Part 2 – Application to Foreign Affiliates and Others

The Market Regulator considers that any use by a Participant of another person that is not subject to Rule 6.4 in order to make a trade off of a marketplace (other than as permitted by one of the exemptions) to be a violation of clause (a) of subsection (2) of Rule 2.1 respecting specific unacceptable activities.

Although certain affiliated entities of a Participant, including their foreign affiliates, are not directly subject to Requirements, Rule 6.4 means that a Participant may not transfer an order to a foreign affiliate, or book a trade through a foreign affiliate, and execute the order in a manner that does not comply with Rule 6.4. In other words, an order directed to a foreign affiliate by the Participant or any other person subject to Rule 6.4 shall be executed on a marketplace unless one of the exemptions set out in Rule 6.4 applies. Foreign branch offices of a Participant are not separate from the Participant and as such are subject to Requirements.

Part 3 – Non-Canadian Accounts

Clause (2)(e) of Rule 6.4 permits a Participant to trade off of a marketplace either as principal with a non-Canadian account or as agent for the purchaser and seller both of whom are non-Canadian accounts. A "non-Canadian account" is defined as an account of a client of the Participant or a client of an affiliated entity of the Participant held by a Participant or an affiliated entity of a Participant and the client is considered to be a non-resident for the purposes of the Income Tax Act (Canada). There may be certain situations arising where a Participant is uncertain whether a particular account is a "non-Canadian account" for the purpose of this exemption. In these situations the account should be treated as a “Canadian account”. The fact that an individual may be located temporarily outside of Canada, that a foreign location is used to place the order or as the address for settlement or confirmation of the trade does not alter the account's status as a Canadian account. Trades made by or on behalf of bona fide foreign subsidiaries of Canadian institutions are considered to be non-Canadian accounts, if the order is placed by the foreign subsidiary.

For the purpose of this Policy, the relevant client of the Participant is the person to whom the order is confirmed.

Part 4 – Reporting Foreign Trades

Clause (2)(e) of Rule 6.4 requires a Participant to report to a marketplace any trade in a listed security or a quoted security that is made as principal with a non-Canadian account or as agent if both the purchaser and seller are non-Canadian accounts, unless the trade is reported to a foreign organized regulated market. If such an “outside Canada” trade has not been reported to a foreign organized regulated market, a Participant shall report such trade to a marketplace no later than the close of business on the next trading day. The report shall identify the security, volume, price (in the currency of the trade and in Canadian dollars) and time of the trade.

Part 5 – Application of UMIR to Orders Not Entered on a Marketplace

Under Rule 6.4, a Participant, when acting as principal or agent, may not trade nor participate in a trade in a security by means other than the entry of an order on a marketplace except in accordance with an exemption specifically enumerated within Rule 6.4. For the purposes of UMIR, a “marketplace” is defined as an Exchange, QTRS or an ATS and a “Participant” is defined essentially as a dealer registered in accordance with securities legislation of any jurisdiction and who is a member of an Exchange, a user of a QTRS or a subscriber to an ATS. If a person is a Participant, certain provisions of UMIR will apply to every order handled by that Participant even if the order is entered or executed on a marketplace that has not adopted UMIR as its market integrity rules or if the order is executed over-the-counter. In particular, the following provisions of UMIR and the Corporation Rules will apply to an order handled by a Participant notwithstanding that the order is not entered on a marketplace that has adopted UMIR:

  • Rule 4.1 prohibits a Participant from frontrunning certain client orders;
  • Part C of Corporation Rule 3100 - Best Execution Of Client Orders with respect to the “best execution obligation” of a client order;
  • Rule 8.1 governing client-principal trading; and
  • Rule 9.1 governing regulatory halts, delays and suspensions of trading.

In accordance with Rule 11.9, UMIR will not apply to an order that is entered or executed on a marketplace in accordance with the Marketplace Rules of that marketplace as adopted in accordance with Part 7 of the Trading Rules or if the order is entered and executed on a marketplace or otherwise in accordance with the rules of an applicable regulation services provider or in accordance with the terms of an exemption from the application of the Trading Rules.

Part 6 – Foreign Currency Translation

If a trade is to be executed on a foreign organized regulated market in a foreign currency, the foreign trade price shall be converted to Canadian dollars using the exchange rate the Participant would have applied in respect of a trade of similar size on a foreign organized regulated market in that foreign jurisdiction in order to determine whether the condition in subsection (3) of Rule 6.4 restricting avoidance of Part 6 of the Trading Rules has been met. The Market Regulator regards a difference of one trading increment or less as "marginal" because the difference would be attributable to currency conversion. A Participant shall maintain with the record of the order the exchange rate used for the purpose of determining whether a better priced order existed on a marketplace and such information shall be provided to the Market Regulator upon request in such form and manner as may be reasonably required by the Market Regulator in accordance with subsection (3) of Rule 10.11.

Rule Text
  1. A Participant shall immediately enter for display on a marketplace that displays orders in accordance with Part 7 of the Marketplace Operation Instrument a client order to purchase or sell 50 standard trading units or less of a security unless:
    1. the client has specifically instructed the Participant to deal otherwise with the particular order;

    6. the order has a value of more than $100,000;
    7. the order is part of a trade to be made in accordance with Rule 6.4 by means other than entry on a marketplace; or
    8. the client has directed or consented to the order being entered on a marketplace as:
      1. a Call Market Order,

      3. a Special Terms Order,

    2. if the Participant executes the client order against a principal order or non-client order, a better price than the price the client would have received if the client order had been executed on receipt by the Participant.

POLICY 6.3 – EXPOSURE OF CLIENT ORDERS

Part 1 – Reviewing Small Orders for Market Impact

Rule 6.3 requires a Participant to immediately enter client orders for the purchase or sale of 50 standard trading units or less on a marketplace. This requirement is subject to certain exceptions. The Participant may withhold the order based on a determination that market conditions were such that immediate entry of the order would not be in the best interests of the client. If the order is withhold the Participant must guarantee that the client receives a price at least as good as the price the client would have received had the client order been executed on receipt by the Participant. If the order is executed against a principal order or non-client order the client must receive a better price.

Part 2 – Confirmation of Order Terms

Pursuant to Rule 6.3, a Participant may withhold entry of the order and return the order to its source for confirmation of its terms. For example, a Participant who receives an order to sell a security at $3 in a stock trading at $20 may return the order to the branch, as it is likely that either the price or the stock symbol is wrong.

Part 3 – Client Request to Withhold Order

A Participant does not have to immediately enter a client order on a marketplace if the client has requested that the order be withheld (for example, the client does not want the order executed in the open market but wishes to do a tax-related trade with their spouse).  Any request must be specific to that order. A client cannot give a blanket request to withhold any future orders the client may give the Participant.  Furthermore, the Participant may not solicit a request to withhold the order. A Participant must keep a record of the client’s request to withhold orders for seven years from the date of the instruction and, for the first two years, the request must be kept in a readily accessible location.

See CIRO Bulletin 24-0349“Amendments Respecting the Reasonable Expectation to Settle a Short Sale” (December 5, 2024).

Rule Text
  1. A Participant shall not enter on a marketplace or an organized regulated market a principal order or a non-client order of the Participant that, based on the information known or reasonably available to the person or persons originating or entering the principal order or non-client order, the Participant knows or should have known will execute or have a reasonable likelihood of executing in priority to a client order received by the Participant prior to the entry of the principal order or non-client order for the same security that is:
    1. at the same price or a lower price than the client order in the case of a purchase or the same or a higher price than the client order in the case of a sale; and
    2. on the same side of the market.
  2. Despite subsection (1) but subject to Rule 4.1, a Participant is not required to give priority to a client order if:
    1. the client specifically has consented to the Participant entering principal orders and non-client orders for the same security at the same price on the same side of the market on the same settlement terms;
    2. the principal order or non-client order is:
      1. automatically generated by the trading system of a marketplace in respect of the Marketplace Trading Obligations of that marketplace,
      2. automatically generated by a system operated by the Participant or on behalf of the Participant based on pre-determined order and trading parameters established, programmed and enabled for trading prior to the receipt of the client order,
      3. for a managed account and the client order is for a managed account under the direction of the same person and in respect of which executions are allocated between the various managed accounts on an equitable basis in accordance with the established practices of the Participant,
      4. a Basis Order,
      5. a Contingent Derivative Order, or
      6. a Net Asset Value Order;
    3. the client order has been entered directly by the client of the Participant on a marketplace;
    4. the principal order or non-client order is executed pursuant to an allocation by the trading system of a marketplace and:
      1. either:
        1. the security which is the subject of the order trades on no marketplace other than that marketplace,
        2. the principal order or non-client order is a Call Market Order, a Contingent Derivative Order, an Opening Order, a Market-on-Close Order, a Net Asset Value Order or a Volume-Weighted Average Price Order,
        3. each of the client order and the principal order or non-client order was entered on the same marketplace,
        4. the client has instructed the Participant to enter the client order on a particular marketplace, or
        5. the client has instructed the Participant to enter the client order in a manner that does not disclose the identifier of the Participant in a consolidated market display,
      2. the client order was entered by the Participant on that marketplace immediately upon receipt by the Participant, and
      3. if the client order was varied or changed by the Participant at any time after entry, the variation or change was on the specific instructions of the client;
    5. either the client order or the principal order or non-client order is a Special Terms Order and the client order would not have executed in the transaction or transactions involving the principal order or non-client order due to the terms and conditions of at least one Special Terms Order; or
    6. a Market Integrity Official requires or permits the principal order or non-client order to be executed in priority to a client order.
  3. For the purposes of clause (2)(a), a client shall be deemed to have consented to the Participant entering principal orders and non-client orders for the same security at the same price on the same side of the market on the same conditions and settlement terms if the client order, in accordance with the specific instructions of the client, is to be executed in part at various times during the trading day or at various prices during the trading day.

POLICY 5.3 – CLIENT PRIORITY

Part 1 – Background

Rule 5.3 restricts a Participant and its employees from trading in the same securities as a client of the Participant. The restriction is designed to minimize the conflict of interest that occurs when a Participant or its employee compete with the firm’s clients for execution of orders. The Rule governs:

  • trading ahead of a client order, which is taking out a bid or offering that the client could have obtained had the client order been entered first. By trading ahead, the pro order obtains a better price at the expense of the client order.
  • trading along with a client, or competing for fills at the same price.

The application of the rule can be quite complex given the diversity of professional trading operations in many firms, which can include such activities as block facilitation, market making, derivative and arbitrage trading. In addition, firms may withhold particular client orders in order to obtain for the client a better execution than the client would have received if the order had been entered directly on a marketplace. Each firm must analyze its own operations, identify risk areas and adopt compliance procedures tailored to its particular situation.

A Participant has overriding agency responsibilities to its clients and cannot use technical compliance with the rule to establish fulfillment of its obligations if the Participant has not otherwise acted reasonably and diligently to obtain best execution of its client orders. 

Part 2 – Prohibition on Intentional Trading Ahead

A Participant can never intentionally trade ahead of a client order that is either a market order or tradeable limit order received prior to the entry of the principal order or non-client order except in accordance with an exemption from the requirements of Rule 5.3(1), which exemptions include obtaining the specific consent of the client. Examples of "intentional trades” include, but are not limited to:

  • withholding a client order from entry on a marketplace (or removing an order already entered on a marketplace) to permit the entry of a competing principal order or non-client order ahead of the client order;
  • entering a client order on a relatively illiquid market (other than on the instructions of the client) and entering a principal order or non-client order on a more liquid marketplace where the principal order or non-client order is likely to obtain faster execution;
  • adding terms or conditions to a client order (other than on the instructions of the client) so that the client order ranks behind principal orders or non-client orders at that price;
  • putting terms or conditions on a principal order or non-client order for the purpose of differentiating the principal order or non-client order from a client order that would otherwise have priority at that price; and
  • entering a principal order or non-client order as an “anonymous order” (without the identifier of the Participant) which results in an execution in priority to a previously entered client order that discloses the identifier of the Participant.

Part 3 – No Knowledge of Client Order

The Participant must have reasonable procedures in place to ensure that information concerning client orders is not used improperly within the firm. These procedures will vary from firm to firm and no one procedure will work for all firms. If a firm does not have reasonable procedures in place, it cannot rely on the exceptions. Reference should be made to Policy 7.1 – Policy on Trading Supervision Obligations, and in particular Part 4 – Specific Procedures Respecting Client Priority.

If a client has instructed a Participant to withhold an order or has granted a Participant discretion with respect to the entry of an order, details of the instruction or grant of discretion must be retained for a period of seven years from the date of the instruction or grant of discretion and, for the first two years, the consent must be kept in a readily accessible location.

Part 4 – Client Consent

A Participant does not have to provide priority to a client order if the client specifically consents to the Participant trading alongside or ahead of the client. The consent of the client must be specific to a particular order and details of the agreement with the client must be noted on the order ticket. A client cannot give a blanket form of consent to permit the Participant to trade alongside or ahead of any future orders the client may give the Participant.

If the client order is part of a pre-arranged trade that is to be completed at a price below the best bid price or above the best ask price as indicated on a consolidated market display, the Participant will be under an obligation to ensure that “better-priced” orders on a protected marketplace are filled prior to the execution of the client order. Prior to executing the client order, the Participant must ensure that the client is aware of the better-priced orders and has consented to the Participant executing as against them in priority to the client order. The consent of the client must be noted on the order ticket.

If the client has given the Participant an order that is to be executed at various times during a trading day (e.g. an “over-the-day” order) or at various prices (e.g. at various prices in order to approximate a volume-weighted average price), the client is deemed to have consented to the entry of principal orders and non-client orders that may trade ahead of the balance of the client order. Unless the client has provided standing written instructions that all orders are to be executed at various times during the trading day or at various prices during the trading day, the client instructions should be treated as specific to a particular order and the details of the instructions by the client must be noted on the order ticket. However, if the un-entered portion of the client order would reasonably be expected to affect the market price of the security, the Participant may be precluded from entering principal orders or non-client orders as a result of the application of the frontrunning rule.

In certain circumstances, a client may provide a conditional consent for the Participant to trade alongside or ahead of the client order. For example, a client may consent to a principal order of Participant sharing fills with the client order provided the client order is fully executed by the end of the trading day. If the client's order is not fully executed, the client may expect that the Participant "give up" its fills to the extent necessary to complete the client order. In this situation, the Participant should mark its orders as "principal" throughout the day. Any part of the execution which is given up to the client should not be re-crossed on a marketplace but should simply be journalled to the client (since the condition of the consent has not been met, the fills in question could be viewed as properly belonging to the client rather than the principal order). To the extent that a Participant "gives up" part of a fill of a principal order to a client based on the conditional consent, the Participant shall report the particulars of the "give up" to the Market Regulator not later than the opening of trading on marketplaces on the next trading day. The conditional consent of the client must be specific to a particular order. The details of the agreement with the client must be noted on the order ticket.
