That reminds me, back in the 1980's my Grandfather bought a vehicle shop building from CFB Cornwallis and had it floated to his nearby property.
He warned us kids about the asbestos side shingle but we broke them off and threw them at each other anyway.
I did read an article in a respectable magazine some years ago that published on the topic. It examined a (then failed) Canadianasbestos mine, workers and the nearby population. It concluded that aside from extreme exposure cases, Asbestos had been excessively demonized by the OH&S industry.
Most folks treat Asbestos with greater fear than radioactivity these days.
