The Environmental Health Clinic (EHC) is a unique multidisciplinary clinic and the only one of its kind in Ontario. It was established in 1996 by the Ministry of Health and Long-Term Care to be a provincial resource in promoting environmental health and to improve health care for people with chronic complex environmentally-linked conditions such as Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS), Fibromyalgia Syndrome (FMS) and Environmental Sensitivities, including both Multiple Chemical Sensitivity (ES/MCS) and Electromagnetic Hypersensitivity.

The Environmental Health Clinic was established to be the clinical part of a joint clinical and research program of Women's College Hospital and the University of Toronto.
