Titles matter in health care. Only individuals who are registered with the College of Occupational Therapists of Ontario are permitted to call themselves an "occupational therapist", the abbreviation "OT" or any variation of these two titles. All occupational therapists in Ontario may use the designation OT Reg. (Ont.). 

Title is protected by law, and indicates to the public that individuals:

  • have met the requirements to be a member of the regulated profession of occupational therapy;
  • practice according to the standards of the profession; and
  • are accountable to the College for their conduct and practice.

It is important that patients and clients know who is delivering their care. In choosing a registered occupational therapist (OT), the public can be assured that this professional is qualified to deliver safe and quality care.

How Can You Check if Someone is a Registered OT?


To verify that someone is an occupational therapist, search Find an Occupational Therapist. Only those individuals who are listed are qualified and able to practice occupational therapy in Ontario.

When you search the list of people under the Find an Occupational Therapist, you can view all the publicly available information about OTs who are registered, or were previously registered, with the College. Learn more about the information available here.

If you know of someone who calls themselves an occupational therapist or OT and can’t find them on the Public Register, contact the Manager, Investigations & Resolutions.

What Happens if Someone is Not Registered (Illegal Practitioners)?

It is illegal in Ontario for someone to use the title "occupational therapist", the initials “OT” or any variation if they are not registered with the College.

The College has the authority to investigate concerns regarding individuals who hold themselves out to be an occupational therapist without being registered to practice in Ontario. At the conclusion of an investigation, the College may:

  • advise the individual in question of the need to be registered with the College in order to use title;
  • issue a cease and desist order; or
  • proceed with a court injunction or prosecution.
