College of Dietitians of Ontario

What College of Dietitians of Ontario does

The College of Dietitians of Ontario (CDO) is the statutory regulatory body for the dietetics profession in Ontario, established through the Dietetics Act, 1991 and operational since December 31, 1993 under the Regulated Health Professions Act, 1991. It is a not-for-profit organization accountable to the Ontario Minister of Health, headquartered at 175 Bloor Street East in Toronto, with a small staff of 11-50 employees. CDO serves four principal stakeholder groups: Registered Dietitians (4,600+ across Ontario), applicants seeking licensure, employers of dietitians, and the Ontario public.

CDO delivers a suite of regulatory programs rather than commercial products. Core capabilities include the Registration Program (entry-to-practice standards, administration of the Canadian Dietetic Registration Examination (CDRE), annual renewals), the Quality Assurance Program (Self-Directed Learning Tool, Jurisprudence Knowledge and Assessment Tool, and a fully virtual Peer and Practice Assessment), the Practice Advisory Program (telephone/email guidance and standards documentation), the Complaints & Discipline Program (investigations and tribunal proceedings), and a public-facing Register of Dietitians hosted on a web portal (portal.collegeofdietitians.org). Supporting channels include the Learning Hub content site, Reg Talks webinars, an annual workshop series, social media presence, and a livestreamed YouTube channel for Board meetings. Technology is limited to a conventional web-based registrant management portal; no AI, API, or SDK surface is exposed.

CDO is funded almost exclusively by annual registration renewal fees from its 4,600+ RD registrants, supplemented by application fees, with Board-approved fee adjustments of 2% (FY2024-25) and 1% (FY2025-26). Revenue and audited financials are not publicly disclosed. The Board comprises twelve members — six elected dietitians and six government-appointed public members — under a recently restructured governance model with shortened term limits and a new election system introduced in 2025. CDO is operationally embedded in the Ontario health-regulator ecosystem, holding membership in Ontario Health Regulators, the Alliance of Canadian Dietetic Regulatory Bodies, and, as of January 2026, the Health Professions Discipline Tribunal pilot for adjudicative hearings.

• College of Physicians and Surgeons of Ontario: Ontario's statutory regulator for physicians, operating under the same Regulated Health Professions Act, 1991 framework as CDO. It is the closest structural analogue: legislated mandate, public register, complaints/discipline program, and quality assurance — just at far larger scale and budget.
• College of Occupational Therapists of Ontario: Ontario's OT regulator under the RHPA. Mirrors CDO's operating model — public register, QA program, complaints process, registrant renewal fees — at a similar organizational scale.
