About medical radiation technologists

Medical radiation technologists (MRTs) are health care professionals who work in 4 different disciplines:

  • Radiological technology
  • Nuclear medicine
  • Magnetic resonance
  • Radiation therapy

MRTs use sophisticated medical technologies to produce images that are essential for diagnosis, provide treatment for various medical conditions, and plan and deliver ionizing radiation for therapeutic purposes.

Data availability

CIHI's Health Workforce Database (HWDB) collects standardized, comparative data on the supply, demographics, geographic and distribution characteristics, and education and employment details of MRTs in Canada.

Reports and analyses

Regulatory environment

As of 2017, MRTs are regulated in Nova Scotia, New Brunswick, Quebec, Ontario, Saskatchewan and Alberta.

MRTs are not regulated in Newfoundland and Labrador, Prince Edward Island, Manitoba and the territories; these jurisdictions require registration with their provincial associations (there are no territorial associations).

MRTs are also not regulated in British Columbia. Registration with the provincial organization is not required but is often a condition of employment.

  • Register with a provincial regulatory body as required
  • Obtain membership and/or certification with both provincial associations and the CAMRT (a condition of practice in some provinces without regulatory bodies)
