MCS/ES is not new. Over 30 years ago, the Province of Ontario created the “Committee on Environmental Hypersensitivity” and appointed George Thomson, a former provincial court judge, as chairman, with a mandate to study and “advise the Ministry of Health on the occurrence of environmental hypersensitivity in Ontario and on current methods of diagnosis and treatment. Further, the committee was to make recommendations to the ministry concerning future approaches to treatment and research that should be taken”
From the the Legislative Assembly of Ontario Official Records for 17 December 1985:
Hon. Mr. Elston: Members of this House may also recall a six-member committee which was appointed in November 1984 to study a disorder which is known as environmental hypersensitivity, or 20th-century disease. The condition has been described as multiple sensitivities or allergies to a wide range of foods, chemicals and environmental substances.
