Practising physicians, residents, and medical students enrolled in any of the six Ontario faculties of medicine are eligible for OMA membership.

The OMA was founded in 1880 by physicians across the province of Ontario who encouraged the profession to unite and form a provincial medical association.

The Ministry of Health recognizes the organization as the sole negotiator on behalf of physicians in Ontario and has been called a union by Bob Rae, a claim rejected by the OMA.

Published quarterly and delivered to 39,000 physicians, the magazine reaches family doctors, specialists and residents, as well as medical students, in every corner of the province.

Today's OMR continues the tradition of being a vital conduit to the experience of Ontario physicians on the front lines of medicine, where they are working hard every day to meet their patients’ needs and lay the groundwork for a better health-care system.
