Noting the timing re: concern about asbestos in certain water pipes still in place across Regina.

Here in Ottawa, we've had concerns about asbestos in assorted buildings - federally-owned or not - as well. The Revenue Canada Data Centre complex is undergoing remediation, and people working maintenance/repair duty there have already gotten mesiothelioma as a side effect.

None of which helps you with your questions, and I apologise for that.
