Plain-English explainer
What is CIRO?
CIRO is the Canadian Investment Regulatory Organization. It is the national self-regulatory body that oversees Canadian investment dealers, mutual fund dealers, and the marketplaces they trade on. CIRO was created on January 1, 2023, from the merger of the Investment Industry Regulatory Organization of Canada (IIROC) and the Mutual Fund Dealers Association of Canada (MFDA), and took the CIRO name on June 1, 2023. It is recognised by the Canadian Securities Administrators (CSA) under provincial securities legislation.
What CIRO does day-to-day
CIRO has four primary jobs. First, it sets the rules for how Canadian investment dealers and mutual fund dealers operate. The Investment Dealer and Partially Consolidated (IDPC) Rules cover know-your-client and client accounts (Rule 3200 series), supervision (Rule 3900 series), suitability (Rule 3402), best execution (Rules 3120 to 3129), and complaint handling (Rule 3700 series). Mutual fund dealers follow the separate MFD Rules. Second, it sets the Universal Market Integrity Rules (UMIR), which govern equity-marketplace conduct on the TSX, TSXV, CSE, and registered ATSs. Third, it sets the proficiency standard for registered representatives through the CIRO Proficiency Model and approved exams. Fourth, it enforces those rules through investigation, hearing panels, and disciplinary action.
CIRO in the Canadian regulatory map
CIRO sits below the CSA. The CSA is the umbrella for provincial securities regulators (Ontario Securities Commission, Autorité des marchés financiers in Quebec, BC Securities Commission, Alberta Securities Commission, etc.). Each province and territory has its own Securities Act, and the regulators adopt the National Instruments that apply nationally (NI 31-103, NI 81-102, NI 21-101, etc.). CIRO operates within that framework.
CIRO does not regulate banks, insurers, exempt market dealers, or portfolio managers who are not also CIRO members. Banks are federally regulated, with OSFI as their regulator. Insurers fall under provincial insurance regulators. Exempt Market Dealers (EMDs) register with their provincial securities regulators under NI 31-103 §7.1, not with CIRO. See exempt market dealer.
On the protection side, the Canadian Investor Protection Fund (CIPF) covers missing client property when a member firm becomes insolvent: up to $1 million for all general accounts combined, plus separate $1 million limits for registered retirement accounts and for RESPs. It does not cover market losses. CIPF is administratively separate from CIRO but operates in the same regulatory ecosystem.
Why the IIROC and MFDA merger happened
Before 2023, Canada had two SROs in retail securities. IIROC covered investment dealers (full-service brokers, discount brokers, institutional dealers). The MFDA covered mutual fund dealers (advisor channels selling mutual funds only). The split created two parallel rulebooks, two compliance regimes, and two career credentials. For clients, the practical difference was opaque. For dealers, the dual structure added compliance overhead. The CSA approved consolidation in 2022 with a January 1, 2023 effective date. CIRO still runs two rulebooks: the IDPC Rules for investment dealers and the MFD Rules for mutual fund dealers. The CIRO Proficiency Model replaced the course-based requirements for investment dealer Approved Persons, including the CSC, with a 9-exam structure that took effect January 1, 2026. Mutual fund dealer representatives still qualify under NI 31-103, for example with the IFC, the Canadian Investment Funds Course or the CSC.
Becoming CIRO-registered
Approval at a CIRO investment dealer requires sponsorship by the dealer, satisfaction of the CIRO Proficiency Model exam requirements for the role (for Registered Representatives, the CIRE plus the Retail or Institutional Securities Exam; other roles such as Supervisor or Trader have their own exam), filing through the National Registration Database (NRD), and ongoing continuing-education obligations. The Canadian Securities Course (CSC) was the legacy foundational course under IIROC and stopped counting for investment dealer approval on January 1, 2026. It still counts for mutual fund dealer representatives. The CIRE replaced it. See also what replaced the CSC.
FAQ
When was CIRO formed?
CIRO was created on January 1, 2023, when the Investment Industry Regulatory Organization of Canada (IIROC) and the Mutual Fund Dealers Association of Canada (MFDA) consolidated under a single self-regulatory body. It took the CIRO name on June 1, 2023. The consolidation was approved by the Canadian Securities Administrators (CSA) and recognized in each provincial jurisdiction.
What does CIRO regulate?
CIRO oversees more than 106,000 registrants at 250 Dealer Member firms (investment dealers and mutual fund dealers) across Canada, according to its 2026 Annual Report. CIRO also oversees the Universal Market Integrity Rules (UMIR) on Canadian equity marketplaces (TSX, TSXV, CSE, ATSs).
Is CIRO a government agency?
No. CIRO is a self-regulatory organization recognized by the CSA. The CSA member jurisdictions (OSC, AMF, BCSC, ASC, etc.) oversee it, and some delegate functions to it: since April 1, 2025 the OSC has delegated the registration of investment dealers, mutual fund dealers and their representatives to CIRO. CIRO's board includes independent directors.
What's the CIRO Proficiency Model?
The CIRO Proficiency Model is the 9-exam credentialing structure that CIRO rolled out on January 1, 2026 to replace the legacy Canadian Securities Course (CSC) and other proficiency programs for investment dealer Approved Persons. The CIRE is the foundational exam for representatives; eight role-specific exams (Retail Securities, Supervisor, Trader, Derivatives, Institutional Securities, Director and Executive, Chief Compliance Officer, Chief Financial Officer) cover other roles. See /ciro-proficiency-model for details.
Does CIRO regulate banks or insurers?
No. CIRO regulates investment dealers, mutual fund dealers, and the marketplaces they trade on. Canadian banks are federally regulated, with the Office of the Superintendent of Financial Institutions (OSFI) overseeing all banks operating in Canada. Insurers fall under provincial insurance regulators and OSFI for federally chartered companies. A bank's wealth management arm is typically a separate CIRO-registered dealer.
How does CIRO enforce its rules?
CIRO investigates possible breaches of its rules and disciplines firms and individuals. Its hearing panels can impose fines, disgorgement, suspensions, and permanent bans or termination on both firms and individuals.
