I would point to two immediate responses.
One is the importance of source water protection and having source water protection plans that extend beyond the current jurisdiction of Canada's confederation. Water flows, and the need for that water to be safe transcends jurisdiction. There is source water and there are sources of water on reserve, and those should be as clean as sources of water that are off reserve. Partnership is critical. There are many source water protection plans that first nations have with local municipalities in order to talk about the shared jurisdiction and shared prosperity over water.
On the second point, in terms of contamination, this was a huge part of the engagement we've had with hundreds of first nations in bringing forth new legislation to have a robust regulatory and standards regime on reserve. This talks about the shared jurisdiction and the shared prosperity over water, but it also talks about legal mechanisms that first nations can have over their own affairs based on their rights over their lands.
We continue to have this dialogue with first nations in order to build the most robust legislation possible prior to bringing it forward, but certainly source water protection, the availability of appropriate resources and the interactions between provinces, territories and rights holders are critical.
