Is There a Difference Between a Dietitian and a Nutritionist?
In some provinces such as Ontario, indeed there is! In Canada, Registered Dietitians (RDs) are regulated health professionals, and “Dietitian” is a protected title nationwide—similar to “Physician,” “Nurse,” or “Pharmacist.” However, the title “Nutritionist” is not consistently regulated across Canada and remains unregulated in some provinces, including Ontario. Because Dietitians are regulated, you’ll often find them in diverse settings—such as hospitals, nursing homes, diabetes centers, public health organizations, government agencies, research institutions, and health clinics.

Why Choose a Regulated Health Professional?
Choosing a regulated health professional means you’re getting reliable, evidence-based guidance. Just as you would consult a doctor for medical concerns or a pharmacist for medication, it’s wise to consult a regulated dietitian for nutrition advice. Like other healthcare professionals, dietitians are accountable to provincial regulatory bodies, which ensure high standards of education, ethics, and public safety. To become a dietitian, individuals must complete a university degree in food and nutrition from an accredited program, followed by hands-on experience through extensive internships. This rigorous training ensures dietitians are well-versed in nutrition science and equipped to provide sound dietary advice. Additionally, dietitians must stay current with the latest research and adhere to high standards of professional practice throughout their careers.
How to Identify a Registered Dietitian
So, how can you be sure your nutrition provider is a regulated health professional? There are a few ways to confirm! You can:
Contact the regulatory body in your province.
Look for the initials “RD” (or “Dt.P” in French) after their name.
Simply ask them if they’re a Dietitian!
