Older residents of Asbestos, Quebec, remember when the substance for which their town is named was thought to be a miracle material.

The furry silicate mineral was woven into textiles and incorporated into building materials so that they would not burn.

Kaiser Wilhelm sheltered in a portable asbestos hut during World War I. During the next one the U.S. armed forces used the stuff to insulate ships, tanks and aircraft and to make fireproof uniforms. Asbestos found its way into cement, pipes, tiles and shingles.

The Canadian navy launched a corvette in 1943 called the hcms Asbestos. "It [would be] a fantastic material if it didn't kill people," said Jessica van Horssen, author of "A Town Called Asbestos," a book about the town and its place in the global industry.

Now it is known to cause a deadly form of lung cancer. The 1.2-mile open-pit Jeffrey Mine, once the world's largest asbestos mine, shut down in 2012. It remains the most visible feature of the landscape near Asbestos. The town's 5,000 inhabitants are now considering whether to change its name. That might make it easier to attract investment.

Mayor Hugues Grimard said prospective investors treat councilors as if they had a contagious disease. Some refuse to take their business cards.

He believes that a new name is a matter of life and death for the town, which has lost half its population since the peak of asbestos production.

Yet Grimard expects resistance at a town-hall meeting with residents scheduled for Jan. 9. His predecessor suggested a couple of new names in 2006 (Trois-Lacs, which means Three Lakes, and Phoenix). Instead, residents changed the mayor.

"It's an emotional subject," Grimard said. "People are attached to the name because of our heritage and history."

Canada is more attached to asbestos than most countries. The Canadian Cancer Society did not call for a ban on the carcinogen until 2007, when a third of workplace deaths were caused by asbestos. Canada promoted the export of "safe" Quebec asbestos until the early 2010s, when it finally admitted that any use of the material is hazardous. The federal government did not ban asbestos products until 2018. Now the biggest asbestos mine is Asbest, in Russia's Ural mountains.

It may help Grimard's cause that townspeople's memories of work in the mine are less vivid, said van Horssen.

Other Canadian towns have changed their names to improve their image. The inhabitants of Berlin, Ontario, whose heritage is largely German, decided during World War I to call the town Kitchener, after Lord Kitchener, the British field-marshal and secretary of war whose face appeared on recruiting posters.

By contrast the 500 residents of Swastika, Ontario, held fast to the name despite Adolf Hitler's appropriation of the Hindu symbol. They had it first, the locals reasoned. It may have helped that the Swastika mine, after which the town was named, produced gold, not asbestos.
