As of 2010, nine Canadian provinces either regulated the profession of medical radiation technology or required mandatory registration with the Canadian Association of Medical Radiation Technologists (CAMRT) and the association in the province where an MRT plans to work. [...] MRTDB Data Providers The primary data collectors for the MRTDB are the provincial regulatory bodies or the professional associations (except for the British Columbia Association of Medical Radiation Technologists) and the national association (the CAMRT), which provided data on behalf of B. C., Yukon, the Northwest Territories and Nunavut through voluntary registration with the CAMRT. [...] The provincial registrars or the CAMRT capture the information needed for administrative purposes and prepare a subset of the data for CIHI. [...] The breakdown of the 2010 data is shown in Figure 1. Figure 1: Defining the CIHI MRTDB Medical Radiation Technologist Workforce, 2010 Notes The percentages for exclusions are calculated based on the total number of records submitted to the MRTDB. [...] Consequently, the 2008, 2009 and 2010 statistics in this report for all of the above-mentioned provinces represent all MRTs or the entire MRT workforce registered with the provincial regulatory bodies or associations, which provided their membership data to the MRTDB as of August 1 of each year.
