"Dietitian" — A Protected Title
The letters "RD" (Registered Dietitian) after a person's name means that the person is registered with the College of Dietitians of Ontario. All members of the College must ensure that they are clearly identified as a dietitian during the course of practising dietetics by using the title of “Registered Dietitian” or the designation of “RD”, or the French equivalent, “diététiste professionel(le)” and “Dt.P.”
In Ontario, Registered Dietitians are highly educated in the sciences related to foods and human nutrition and they are trained to apply their evidence-based knowledge in a variety of settings.
Registered Dietitians are required to continue their professional development to remain current and expand the competencies needed for delivering safe, ethical, and high quality dietetics services. They have met all the requirements established by the College to determine competence to practice.
Only individuals registered with the College of Dietitians of Ontario can use the titles dietitian, Registered Dietitian, a variation or abbreviation or an equivalent in another language. The law protects these titles and people using them inappropriately can be fined up to $50,000. You can verify that your nutrition provider is a qualified Registered Dietitian by consulting the College's Register of Dietitians.
