1. IDPC Dealer Member Plain Language Rules
Registrants must identify, disclose, and manage material conflicts of interest. Where a conflict cannot be managed, it must be avoided. Conflicts include referral arrangements, proprietary product incentives, compensation conflicts, and personal financial dealings with clients.
Requirements for opening client accounts: identity verification, KYC collection, account documentation, delivery of account-opening documents. Sets the framework for what must be in the account file before the first transaction.
Dealers must establish and maintain a supervisory system: written supervisory procedures, designated supervisors at each branch, trade review processes, annual branch audits, and ongoing monitoring of registered individuals. Failure to supervise is itself a violation.
Branch manager or designated supervisor must approve margin accounts, options accounts, and short-selling accounts. Specific risk disclosure documents must be delivered and acknowledged before first trade. Documents approval requirements by account type and options level.
Before making a trade recommendation, registrants must assess suitability at the account level, not just at the individual trade level. Triggered at account opening, before recommendations, upon KYC trigger events, and on account transfer. Concentration, asset mix, and alignment with objectives are all assessed.
Dealers must take reasonable steps to achieve the most advantageous execution terms for client orders, considering price, speed, certainty of execution, and other relevant factors. Best execution is assessed against the consolidated market at the time of the order.
Operating requirements for branch offices: recordkeeping, branch audits, supervisory controls, communication and correspondence records. Records must be maintained for 7 years. Branch audit must occur at minimum annually.
Acknowledgement letter within 5 business days; substantive response within 90 calendar days; client must be informed of OBSI escalation right. All complaints must be logged and retained. OBSI cap is $350,000 (verify at obsi.ca).
2. UMIR - Universal Market Integrity Rules
UMIR governs trading conduct on Canadian marketplaces. Applies to marketplace participants (dealers and their traders) when entering and executing orders.
Foundational definitions for Universal Market Integrity Rules: marketplace, participant, client, order, trade. Read in conjunction with all other UMIR rules.
General trading conduct requirements: fair, orderly, and efficient markets. Prohibits wash trades, painting the tape, marking the close, and other manipulative practices.
UMIR 3.3: Before executing a short sale, the participant must have a reasonable expectation of being able to borrow the securities for delivery (locate requirement). Naked short selling without a locate is prohibited. Locate must be obtained before order entry, not at settlement.
Marketplace participants must make reasonable efforts to achieve best price for client orders. Must consider all accessible marketplaces. The obligation exists regardless of which marketplace the order is routed to.
Trades executed in dark pools (order facilities without pre-trade transparency) must satisfy minimum price improvement requirements over the consolidated best bid or offer. Without the required price improvement, dark trading is not permitted.
Requirements for order entry: accurate identification of order type, client vs proprietary designation, short sale markers, and compliance with marketplace order types. Misclassifying an order (e.g., marking a short sale as a long) is a UMIR 7 violation.
When a participant fills a client order from its own inventory (principal trades), the trade must achieve best execution for the client. The participant's profit on the principal trade cannot come at the client's expense.
CIRO can halt, delay, or suspend trading in a security when required for market integrity (e.g., pending material news). During a halt, no orders may be entered, amended, or executed. Halts may be market-wide or security-specific.
3. NI 31-103, NI 21-101/23-101/23-103, NI 81-Series, NI 41-101, and PCMLTFA
Mandatory fields registrants must collect: identity, investment objectives, time horizon, risk tolerance, risk capacity, annual income, net worth, investment knowledge, other accounts, specific financial goals, material liabilities.
Referral arrangements between registrants and non-registrants must be disclosed in writing to the client before the referral service is provided. Disclosure must include the nature of the arrangement, compensation paid, and any resulting conflicts.
Registered individuals must disclose OBAs to their registered dealer before engaging in them. The dealer reviews and approves, prohibits, or conditions the activity. Failure to disclose is a compliance violation.
Prohibits registrants from borrowing from or lending to clients, entering arrangements where compensation depends on client returns outside approved structures, or accepting gifts that could influence conduct.
Registrants must keep accurate records of all client transactions, correspondence, account documents, and financial records for 7 years. Records must be in a form that is accessible for regulatory inspection.

4. ITA References That Appear Alongside CIRO Rules
Income or loss from property transferred or loaned to a spouse or common-law partner attributes back to the transferor.
Income (not capital gains) from property transferred or loaned to a related minor attributes back to the transferor until the minor turns 18.
Capital gains (not income) on property transferred (not loaned) to a spouse or CLP also attribute back to the transferor.
Attribution rules do not apply if property is loaned at CRA's prescribed rate, interest is paid by January 30 of the following year, and the arrangement is documented.
Certain split income received by minors (including private-corporation dividends) is taxed at the highest marginal rate regardless of the minor's actual income.
The contributing spouse deducts spousal RRSP contributions against their own income. The three-year attribution rule (ITA s.146(8.3)) applies to withdrawals within 3 calendar years of the last contribution.
Capital losses are denied if the taxpayer (or affiliated person) reacquires substantially identical property within 30 days before or after the sale. Denied loss is added to the adjusted cost base of the reacquired property.
Net capital losses can only offset capital gains. Unused net capital losses carry back 3 years or forward indefinitely.
Up to 50% of eligible pension income (RRIF withdrawals age 65+, DB pension, certain annuities) can be allocated to a spouse for tax purposes. CPP and OAS do not qualify under this provision.
Test Yourself: 5 Rule Citation Questions
Q1. Which UMIR rule requires a short seller to have a reasonable expectation of being able to borrow securities before entering a short sale order?
Show answer
UMIR 3.3 (the short-sale locate requirement). The participant must locate borrowable shares before order entry, not at settlement. Naked shorting without a locate is prohibited.
Q2. Under NI 81-101, what must a mutual fund dealer deliver to an investor before the investor's purchase is completed?
Show answer
The Fund Facts document (2-page summary). Delivery before purchase triggers the investor's right of withdrawal. The simplified prospectus is filed with regulators but delivery of the Fund Facts is the investor-facing obligation.
Q3. A client receives income from a family loan that does not charge the CRA prescribed rate. Under which ITA section does the income attribute back to the lender?
Show answer
ITA s.74.1(1) if the recipient is a spouse or CLP; ITA s.74.1(2) if the recipient is a related minor. The prescribed-rate loan exception in ITA s.74.5(2) would have prevented attribution, but it requires the loan to be at the CRA prescribed rate with interest paid by January 30.
Q4. Which NI governs electronic trading risk controls and direct electronic access (DEA)?
Show answer
NI 23-103. It requires pre-trade filters, credit limits, kill-switch capabilities, and places responsibility on the participant for orders entered by DEA clients.
Q5. Under IDPC Rule 8000 series, what is the deadline to send an acknowledgement letter after receiving a client complaint?
Show answer
5 business days from receipt of the complaint. The substantive response is due within 90 calendar days. Both deadlines and the right to escalate to OBSI must be communicated to the client.
