CAREX Canada (CARcinogen EXposure) is a multi-institution team of researchers and specialists with expertise in epidemiology, risk assessment, toxicology, geographic information systems, and knowledge mobilization. Its purpose is to provide a body of knowledge about Canadians’ exposures to known and suspected carcinogens in order to support organizations in prioritizing exposures and in developing targeted exposure reduction policies and programs. CELA has a longstanding relationship with CAREX that includes a working group that meets twice a year to share information, and discuss issues of mutual concern and/or collaboration.
