Definition
The MFDA regulated mutual fund dealers across all Canadian provinces except Quebec (where the AMF regulated them) until December 31, 2022. On January 1, 2023, the MFDA merged with IIROC to form CIRO, and the MFDA rulebook was incorporated into the CIRO IDPC Rules as the basis for the mutual fund dealer section. Core MFDA obligations - KYC, suitability, supervision, complaint handling - mapped closely to the IIROC framework and are now aligned under the unified CIRO ruleset. References to MFDA rules in pre-2023 materials should be read against the equivalent CIRO IDPC provisions.
