The DOHS program is thus no longer being offerred.

A list of degree, diploma and certificate programs offered in Canada is available at the Canadian Centre for Occupational Health and Safety:

The Program in Occupational Health and Environmental Medicine (POHEM), formerly known as the Occupational Health Program, was established in 1977 through a grant from the Ontario Ministry of Labour and support from several industries. The Program became one of the leaders in the field of occupational health and was involved in education, research and provision of services. Its two previous directors were Dr. David Muir (1977-1997) and Dr. Harry Shannon (1999-2005).

In 2006, a  reorganization took place, which resulted in the Research and Services components being moved elsewhere in the University. The Research components moved to several departments including the Departments of Clinical Epidemiology & Biostatistics, Medicine and Family Medicine. POHEM research efforts prior to the move on 2006 are listed in this website under the Research Section.

The Service components of the POHEM had included: (i) the Occupational Health Clinic for Small Industries which closed effective January 2006; and (ii) the Occupational and Environmental Health Laboratory (OEHL) which has moved to the Department of Chemistry in the Faculty of Science effective July 1, 2006. Please visit the laboratory website at for further information on the services they provide.

The POHEM, with its new administrative home in the School of Rehabilitation Sciences, Faculty of Health Sciences, is now focused mainly on the provision of education and training. The major educational effort being our Diploma in Occupational Health and Safety (DOHS) which has been offered every year since 1979 and as of May 2010 has graduated 455 students of which approximately 25% are physicians, 15% nurses, 15% hygienists and 45% are other health and safety professionals. Our students have come from Ontario, other parts of Canada, as well as 32 countries around the world.

The Faculty and Staff of the program are proud of their achievements since its inception in 1977. We know, though, that we still have much to do. Too many workers are killed by or suffer from their jobs.  Our aim is to ensure that not only are workers free from occupational hazards, but that they can also find fulfillment and satisfaction from their jobs.  

Our website describes our past and present education, research and services, all dedicated to improving workers health and safety.
