Timeline: The history of asbestos use in Canada

1870s: Quebec becomes the first province to mine asbestos.

1920s: The Metropolitan Life Insurance Company creates the Department of Industrial Hygiene at McGill University. Asbestos is believed to be making workers ill and causing a “dust disease” of the lungs.

1930s: The Metropolitan organization commissions a study with 200 male participants living with asbestosis, a type of lung disease that inflicts the lungs with scars and makes it difficult to breathe.

February 14, 1949: Quebec asbestos miners from the Asbestos and Thetford mines embark on a strike to fight to improve working conditions and wages. The strike is carried out for over five months before a settlement is reached in July. Wages increase by five cents, 10 cents short of the workers asking price.

1966: J. Corbett McDonald, a McGill University professor embarks on a study of the effects of chrysotile mining in Canada. The study receives about $500,000 in funding from the Quebec Asbestos Mining Association.

The research indicates that chrysotile asbestos is not responsible for causing lung tumours detected in the miners. McDonald’s study also examines the mortality rates linked to asbestos.
