That's right.
Just to pick up a bit on the piping, the asbestos cement pipes that are used in Canada are made of a mix of cement that contains asbestos within it. We know they have up to 12% asbestos, which is quite a high content. That's one of the main uses that we see.
We also know that construction workers installing these drainage pipes are supposed to use a snap-cutting technology that wouldn't create dust. However, in the small, tight spaces where they're being installed, the snap-cutting device doesn't fit, so they're using saws to cut it. That causes the dust to be released, and of course they're therefore being exposed.
