College of Dietitians of Ontario

The College of Dietitians of Ontario was founded through the Dietetics Act, 1991, and became a regulatory body on December 31, 1993.

Its mandate under the Regulated Health Professions Act, 1991, and the Dietetics Act, 1991, is to regulate the profession of dietitians in Ontario in the interest of the public and public protection.

Anyone wishing to practice as a dietitian in Ontario must be registered with the College. We set and enforce standards for qualifications, registration, continuing competence, conduct and ethics of dietitians in Ontario. We assist people in Ontario to access dietitian services, handle their questions and concerns.

There are just over 4,100 Registered Dietitians in Ontario.

The College of Dietitians of Ontario has a duty to protect the public. It is accountable to the  Minister of Health and Long-Term Care to fulfill that duty. The Minister monitors College activities to ensure:

  • that the College legal processes and proceedings regulating the practice of dietetics are carried out according to the laws set out in the Regulated Health Professions Act, 1991,and the Dietetics Act, 1991.
  • that there is the required public representation on College Council. Seven of the fifteen members on the Council are public members who have been appointed by the Ontario Provincial Government to represent public interests;
  • that there is public representation on College Committees where at least one public member sits on each of the seven statutory committees;
  • that Council meetings and discipline hearings are open to the public; and
  • that the College submits an annual report of its activities to the Minister of Health & Long Term Care.


The College is also accountable to the Fairness Commissioner for transparent, objective, impartial and fair registration practices. When requested, the College reports to the Fairness Commissioner on the results and processes of our registration practices. The registration review must demonstrate:

  1. that College requirements for registration are necessary for the practice of dietetics in Ontario;
  2. efficiency and timeliness of registration decision-making; and
  3. the reasonableness of registration fees.
