Applicants from Other Canadian Jurisdictions

To practise as a Respiratory Therapist in Ontario, you must be registered with the College of Respiratory Therapists of Ontario (CRTO). You may not work as a Respiratory Therapist or use the Respiratory Therapist title or designation (e.g., GRT, RRT) in Ontario until you have received written confirmation from the CRTO that your certificate of registration has been issued. Working as an RT includes participating in an employer clinical orientation or training.

This section is intended for applicants who:

  • are currently registered to practise as Respiratory Therapists in other (regulated) Canadian jurisdictions (Alberta, Saskatchewan, Manitoba, Quebec, New Brunswick, Nova Scotia, and Newfoundland and Labrador and Prince Edward Island); and
  • have practised the profession there within the past two years.

If you are practising in a non-regulated jurisdiction (British Columbia, Nunavut, Northwest Territories, and Yukon), please refer to the Applicants from Canadian RT Programs or the Applicants Educated outside of Canada sections of our website.

To start the registration process, you must complete the online application, pay the $75.00 application fee, and submit all required documentation to the CRTO. 

The Application for Registration Guide provides a detailed overview of the registration requirements and process.
