Environmental Health Clinic

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 (FM) 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.

Services Provided

The purpose of the clinic is to:

  • Educate our clients, the public and health-care professionals about environmental health issues.
  • Provide a comprehensive multidisciplinary assessment for clients with complex chronic multisystem conditions such as ES/MCS, ME/CFS and FM and to make recommendations to their treating physicians regarding the management of their ongoing health care needs.
  • Gain a better understanding of the health-care needs of those with these chronic complex multisystem conditions through participation in clinical research.

We are currently trying to gather information that will help improve quality of care at the EHC. We’d appreciate if you would complete this anonymous survey. Importantly, this data will also contribute to informing the current Provincial Task Force for Environmental Health before the June 2018 deadline for their next report. Individuals have the opportunity to have their voices heard to shape future care for those with environmental illness. Please see the survey link below:
