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). 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 account opening (Rule 3401), supervision (Rule 3300 series), suitability (Rule 3402), best execution (Rule 3600 series), branch operations (Rule 3700 series), and complaint handling (Rule 8000 series). 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 provincial regulator writes the local Securities Act and 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 fall under OSFI and provincial banking statutes. Insurers fall under provincial insurance regulators. Exempt Market Dealers (EMDs) register directly with the CSA under NI 31-103 §7.1, not with CIRO. See exempt market dealer.
On the protection side, the Canadian Investor Protection Fund (CIPF) covers eligible client assets at insolvent CIRO dealer members up to $1 million per general account. 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. The IDPC Rules consolidated the IIROC and MFDA rulebooks; the CIRO Proficiency Model consolidated the CSC, the IFC, and the legacy proficiency regimes into a single 9-exam credential structure that took effect January 1, 2026.
Becoming CIRO-registered
Registration with CIRO requires sponsorship by a CIRO member firm, satisfaction of the CIRO Proficiency Model exam requirements (CIRE foundational + role-specific exam such as Retail Securities, Supervisor, Trader, Derivatives), CSA filing through the National Registration Database (NRD), and ongoing continuing-education obligations. The Canadian Securities Course (CSC) was the legacy foundational exam under IIROC and was retired by CIRO on January 1, 2026 for CIRO registration purposes. The CIRE replaced it.

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. The consolidation was approved by the Canadian Securities Administrators (CSA) and recognized in each provincial jurisdiction.
What does CIRO regulate?
CIRO regulates approximately 175 investment dealer member firms and approximately 100 mutual fund dealer member firms across Canada, plus the activities of approximately 30,000 registered representatives. 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.) delegate certain enforcement powers to CIRO under provincial securities legislation. CIRO is governed by an independent board with a majority of public 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. The CIRE is the foundational exam; eight role-specific exams (Retail Securities, Supervisor, Trader, Derivatives, Institutional, Director and Executive, Chief Compliance Officer, Chief Financial Officer) build on it. 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 fall under the Office of the Superintendent of Financial Institutions (OSFI) and provincial banking statutes for their core deposit business. 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 has authority to investigate, levy fines, suspend or terminate registered persons, and require dealer firms to make restitution. Disciplinary outcomes are public on the CIRO Hearing Panels page. Major matters can be referred to provincial securities regulators or to the police for criminal charges.
