The College of Medical Radiation Technologists of Ontario is a regulatory body which operates under two pieces of provincial legislation: the Regulated Health Professions Act, 1991 (RHPA) and the Medical Radiation Technology Act, 1991 (MRT Act).

Links through the government website to some of the legislation which affects the CMRTO and medical radiation technologists are provided in this section for your convenience. You should always refer to the published act for the official version of the legislation.

The links to the legislation are separated into two sections: the legislation and the regulations made under those legislations. The by-laws of the CMRTO are provided under a third section.

All applicants for registration with the CMRTO are required to complete a course in jurisprudence set or approved by the CMRTO.


By-Law and Policy Development and Review Process

The CMRTO develops and implements by-laws and policies and changes to its medical radiation technology legislation with the goal of protecting the public interest through the regulation of MRT practice.

Policy development involves identifying trends or issues that may have an impact on MRT regulation. New government legislation, direction from Council, and other external factors can play a role in helping the CMRTO identify and shape its policies. These policies in turn shape the CMRTO’s by-laws.

All existing by-laws and policies at the CMRTO are reviewed by Council, comprised of both professional and public members, on a regular basis. A regular policy review cycle ensures policies remain relevant, accurate and reflective of current expectations.

Council makes decisions at all key stages of the by-law and policy development or review process. The CMRTO Council consults with its members and stakeholders when developing and reviewing by-laws and policies. Council considers, and ultimately approves, all CMRTO policies.




The Medical Radiation Technology Act, 1991 (MRT Act) and the Regulated Health Professions Act, 1991 (RHPA) determine how the medical radiation technology profession is regulated in Ontario.



Regulations that govern the practice of medical radiation technology are made under the RHPA and the MRT Act.



The CMRTO’s by-laws are the rules that govern how the CMRTO operates. Government legislation authorizes Council to make by-laws related to the CMRTO's governance, administration and regulatory functions.
