Start with the role, then connect it to the organisation. Follow a worked example and keep the distinction close for your next session.
Compare the roles.
Read across to compare. Read down to focus on one organisation.
Provincial and territorial securities authorities
Main role
Administer and enforce securities and derivatives law within their jurisdictions.
Scope
Legal powers come from provincial or territorial legislation; these authorities also recognize and oversee self-regulatory organisations.
Important distinction
They retain statutory jurisdiction even when functions such as dealer registration are delegated to CIRO.
Canadian Securities Administrators (CSA)
Main role
Coordinate the work of Canada's provincial and territorial securities regulators.
Scope
Support harmonized regulation; national and multilateral instruments are adopted through the relevant jurisdictions.
Important distinction
The CSA is their coordinating association, not a single federal securities commission.
Canadian Investment Regulatory Organization (CIRO)
Main role
Set and enforce self-regulatory requirements for the dealers and trading activity within its scope.
Scope
Oversee investment dealers, mutual fund dealers and trading on regulated marketplaces; perform delegated registration functions.
Important distinction
CIRO is a recognized self-regulator overseen by securities authorities, not the CSA or a legislature.
The provincial and territorial authorities are the CSA's members. They coordinate through the CSA and oversee CIRO as a recognized self-regulator. These are related roles, not three levels of government or three names for one body.
Put the distinction to work.
An analyst reads a harmonized securities instrument and a separate CIRO trading rule. She asks whether they were issued by the same body.
No. The CSA coordinates work across securities authorities, with instruments adopted in the relevant jurisdictions. CIRO sets self-regulatory requirements within its recognized scope. Related requirements can apply to the same dealer without coming from the same legal role.
Keep this in mind.
Start with the role: provincial and territorial authorities supply statutory oversight; the CSA coordinates them; CIRO carries out recognized self-regulation and delegated functions.
