Thanks for the clarification.
I think the concept to me is choice or autonomy of a first nation in the choice of standards—in this case for clean drinking water and later in waste water—between national standards or provincial and territorial standards, which are sometimes more strident.
If there is no choice made, I would point to clause 18, which talks about the causal impact of the lack of application of standards and then what would be the effects and relationship with the minister. I believe those things are covered in clause 18.
