We are the regulatory body for medical radiation and imaging technologists in Ontario. Our primary responsibility is to serve and protect the public interest by establishing standards of practice for the profession and setting entry to practice requirements for medical radiation and imaging technologists. Additionally, we ensure the continued competence of our members through our quality assurance program and address concerns from the public through our complaints and discipline process.

About Our Registrants

Our registrants are made up of medical radiation and imaging technologists who have been extensively trained to create diagnostic images of patient’s bodies or administer radiation therapy, in five specialties: radiography, nuclear medicine, radiation therapy, magnetic resonance and diagnostic medical sonography. The CMRITO public register provides trustworthy, relevant and up-to-date information about our registrants.
