Understanding Asbestos
Learn about asbestos, its uses in Canada, and why it poses serious health risks
What is Asbestos?
Asbestos is a group of naturally occurring fibrous minerals that were widely used in construction and manufacturing due to their heat resistance, strength, and insulating properties.
These microscopic fibers, when disturbed, become airborne and can be inhaled or ingested, leading to serious health complications decades later.
There are six types of asbestos minerals, with chrysotile (white asbestos), amosite (brown asbestos), and crocidolite (blue asbestos) being the most commonly used in commercial applications.
Asbestos Use in Canada
Canada was one of the world's largest asbestos producers and consumers, with widespread use continuing well into the 1980s and beyond.
Mining Era
Canada operated major asbestos mines in Quebec from the 1870s to 2011, producing millions of tons of asbestos for domestic and international use.
Construction Boom
Post-WWII construction boom saw extensive use of asbestos in buildings, schools, hospitals, and residential homes across Canada.
Regulation Timeline
Partial bans began in the 1970s, with comprehensive bans not implemented until 2018, leaving millions of Canadians exposed.
