Dealer Members – Material Changes

Requesting a Business Change

The Investment Dealer and Partially Consolidated Rules (IDPC), Rule 2246, requires all investment dealers to notify the Canadian Investment Regulatory Organization (CIRO) of changes in ownership or changes in structure, or material changes to their business activities (collectively, a "Business Change").

Becoming a Dual-Registered Member

Existing Members can become registered as both an investment dealer and a mutual fund dealer. This will permit the Members to carry out both investment dealer business and mutual fund dealer business within the same legal entity. These firms are known as dual-registered Members.
