Canadian asbestos ban a no-brainer

It's decades overdue, but the Canadian government has finally committed to completely banning the use of asbestos in Canada by 2018. It will join a list of only 50-odd countries, including Australia, Japan and the European Union, to ban the known carcinogen.
The World Health Organization declared asbestos a dangerous carcinogen way back in 1987, and yet government after Canadian government refused to ban it. Asbestos is known to cause lung cancer, mesothelioma, asbestosis and other cancers, and in Canada alone over 2,000 people a year are diagnosed with asbestos-related cancers. It is recognized as the top single cause of workplace deaths in Canada. Canada has one of the world's highest rates of mesothelioma, a particularly virulent form of cancer specifically associated with exposure to asbestos. Even with the ban, because of the long latency period of diseases like mesothelioma and lung cancer, and because of the ongoing exposure to asbestos, it is likely that the mean rates of the diseases have not yet peaked.
Canada started mining asbestos in the 1870s, principally in Quebec, and soon became one of the world's largest producers, before closing its last asbestos mine as recently as 2011. For years, both provincial and federal governments dragged their feet and even actively supported the country's asbestos mining industry despite the known health risks. Even now, the mining and processing of asbestos tailings in Quebec in order to extract magnesium is specifically excluded from the new ban.
Another issue that needs to be addressed is the importing of asbestos. Currently, Canada imports over $8 million worth of asbestos-related products, about half of which is in the form of brake pads and linings for automobiles (Canadian and American vehicle manufacturers have largely replaced the asbestos in brake pads with safer alternatives), and some industrial pipes. This import problem is expected to be dealt with by the ban, a move that is being applauded by the wrecking and vehicle-recycling industry.
The details of the ban will be thrashed out in a 2-year government-led consultation process. But finally something concrete is being done about this no-brainer of an issue.
