Canada ban on asbestos takes effect but mining residues are exempt
Quebec companies will be free to extract magnesium from asbestos tailings
Canada's ban on the import, sale and use of asbestos will not prevent companies in Quebec from sifting through the waste left over from decades of mining asbestos to look for magnesium.
Environment Minister Catherine McKenna plans to announce the new regulations implementing the ban on Thursday in Ottawa, but cabinet gave the nod of approval to them at the end of September.
Kathleen Ruff, an expert on asbestos, says it is disappointing Ottawa is allowing an exemption from the ban for mining residues because those tailings contain as much as 40 per cent asbestos fibres, which are known to cause cancer and other lung diseases.
At least one company is working on a project to extract magnesium from the asbestos tailings largely for use in car parts and pressure moulds.
Canada agreed to ban asbestos in 2016, after years of pressure from health experts and former workers and their families, but Canada continued to argue it was safe if used with proper precautions.
In 2016, at least 510 Canadians died of mesothelioma, an asbestos-linked lung cancer, but that number doesn't include deaths in Quebec, which stopped reporting its asbestos-related disease rates in 2010.
