The Royal College currently defines the requirements for specialty education in 70 areas of medical, surgical and laboratory medicine. OMSOC was formed in 2006, around the same time as Occupational Medicine changed from being a 5-year specialty program to a 2-year subspecialty of Internal Medicine (i.e. 3 years of Internal Medicine plus 2 years of Occupational Medicine). This represented significant changes in the model training. One of OMSOC's initial roles was to represent the specialty of Occupational Medicine to the Royal College of Physicians and Surgeons of Canada – the organization that accredits residency training programs in Canada.
