Before asbestos mining came to the United States, it was already commonplace in Canada. Quebec was a large mining area, though mines operated in cities throughout Canada. At one point, Canada had several dozen mines in operation and was the largest exporter of asbestos to the U.S. and many other countries.Miners Exposed to Asbestos - Find Out How and When,The last asbestos mine was shut down in 2002, but during the 1970s, asbestos mining was at its height. Hundreds of thousands of people worked directly and indirectly in asbestos mining and manufacturing asbestos-related products, and many miners are only just seeing the health impacts now.
