Wondering if Western Gypsum dryall products contained asbestos. Am planning to take for testing, just looking for a quick answer or link to a list of Canadian products that contained asbestos.

  • Good chance...until early 1990’s. – Lee Sam Apr 9 '18 at 0:21
  • Some or all Canadian drywall contained asbestos until the early 1990s?! Did any drywall sold in the US around 1970 contain asbestos? – Jim Stewart Apr 9 '18 at 1:32
  • @JimStewart The “asbestos act” was passed in 1989, but they allowed the “use” of existing asbestos gypsum board in warehouses. Crazy, huh? Canada I don’t know about. – Lee Sam Apr 9 '18 at 2:20
