I'll start.
I think Health Canada is moving in the right direction with its guideline and then in revisions to the guideline that include specific changes to how samples are collected. That really helps water utilities in some sense drive the issue to their funders, decision-makers, when you have a clear guidance at the federal level. There does have to be some kind of coordination among the provinces, though, of the regulators. In Alberta, it's Alberta Environment, the Ministry of the Environment in Ontario, and so on.
Ensure we have some kind of consistency across the country. That's an important one to move in the right direction.
