Why Regulation Matters

Public Protection

In Ontario, the law sets out the responsibilities, powers and procedures for the College of Dietitians of Ontario to regulate the profession of dietetics in the interest of public protection.

The College works for the public to ensure that dietitians are qualified to offer safe, competent and ethical dietetic services. 

Enforceable Professional Standards

A high standard for academic and practical training must be achieved to practice as a dietitian in Ontario. The College establishes and enforces standards for entry-to-practice, professional scope of practice, ethics, professional conduct and continuing competence.


While anyone can legally provide nutrition education and advice, what sets dietitians apart is that, under the Regulated Health Professions Act, 1991, they are accountable to the College of Dietitians of Ontario for safe, competent and ethical practice. Each dietitian must participate in quality assurance programs to ensure continuing competency. Under certain circumstances, dietitians and employers have an obligation to report dietitians who are not practicing ethically, safely and competently.

Complaints Process

The College has a complaints process available for anyone who has a concern or complaint about a dietitian. The College has the responsibility and power to investigate and take action in all complaints.

Dietitian, A restricted Health Profession Title

In Ontario, only members of the College of Dietitians of Ontario are regulated and authorized to use the "title" dietitian. Individuals who are not members of the College are prohibited from using this professional designation or from holding themselves out as qualified to practice as a dietitian or in a specialty of dietetics.

Verify that your dietitian is registered to practice in Ontario by consulting the Register of Dietitians

If you find that an individual is claiming to be a dietitian and that they are not registered with the College, please contact our Registration Manager
