Health Canada has strikingly revised its position on the health risks of asbestos exposure, bringing the federal government more in line with other developed countries.
The recent changes to the department’s website are significant, with the page about asbestos replacing information that was dated from 2012.
Among the shifts, the site no longer says one form of asbestos – chrysotile, the type that Canada mined and exported for years that is still most commonly used – is “less potent” and does less damage than other types. The World Health Organization and other medical bodies have long said all forms of asbestos are carcinogenic.
In addition, Health Canada no longer says the danger comes when asbestos is inhaled in “significant quantities” (the WHO says there is no safe threshold); and it now clearly says that “breathing in asbestos fibres can cause cancer and other diseases.”
