To practice as a Respiratory Therapist in Ontario, you must hold a certificate of registration with the College of Respiratory Therapists of Ontario (CRTO).
The role of the CRTO is to regulate the profession of Respiratory Therapy in the public interest. As part of this mandate, the CRTO sets the entry-to-practice requirements for safe and ethical practice. For example, completion of an approved education program is a requirement for registration.
You may not work as a Respiratory Therapist or in any way hold yourself out as a person qualified to practice respiratory therapy in the province of Ontario until after you have been issued a certificate of registration.
