Parliament has passed Bill C-37, the First Nations Clean Water Act. This law sets up a legal framework to ensure long-term access to safe drinking water in First Nations communities across Canada.

The government had been working on this problem for years through the Indigenous Services Canada department. Progress happened, but slowly. As of March 2024, the government had lifted 144 long-term drinking water advisories — these are official warnings that tap water isn't safe to drink. By July 2024, there were 70 per cent fewer of these advisories than existed in 2015. English River First Nation lifted its advisory in November 2024 after upgrading its water treatment equipment.

These improvements came one community at a time, mostly by spending money to fix or replace old water treatment systems. But here is the problem: when you rely on funding and government directives alone, improvements can slip backward. Without strong legal requirements and enforceable standards, communities had little way to push back if water quality dropped or projects dragged on.

Bill C-37 changes that foundation.

What the New Law Does

The Act sets enforceable water quality standards that First Nations water systems must meet. Instead of relying on funding agreements and government instructions — which can shift — the law creates legal obligations. First Nations communities can now hold the federal government accountable in court if it fails to meet those obligations.

The legislation also fixes a problem baked into Canada's system of government. Provinces control water standards for cities and towns. First Nations communities on reserve have historically operated under a separate regime, with fewer resources and less attention. Bill C-37 does not hand that responsibility to the provinces. Instead, it creates a federal standard while giving First Nations governments formal authority over their own water systems. Federal funding for water infrastructure becomes a legal duty written into the statute, not something that depends on the government's mood in any given budget.

Budget 2025 included funding to support this shift. The government deliberately tied money to law: the budget commits the resources, and the legislation codifies the obligation to use them.

What Still Needs to Happen

The real work now is in the details. The government will write regulations — the specific rules that explain how high water quality must be, how often systems must be inspected, and how much money First Nations can count on. Those rules will make or break whether this law actually works.

About 30 per cent of the communities that had drinking water advisories in 2015 still had them in mid-2024. This new law does not automatically fix those situations overnight. It changes what the government legally owes these communities and gives them new legal tools to demand action. But actual progress depends on when the regulations get written and when capital projects get built.

First Nations leaders have said the rights-based approach is welcome. At the same time, they are watching closely to see what the actual regulations say. A law that looks good on paper but lacks teeth in the regulations will not solve the problem.

The practical shift here is substantial for government officials and First Nations leadership alike. Indigenous Services Canada moves from managing grants and writing cheques to operating under a legal duty to deliver results. When the government falls short, communities now have legal standing to challenge it — not just political muscle.

The path to this point — from the Liberal Party's 2015 election promise to eliminate all advisories, through several budget cycles, to legislation passed in 2026 — shows how slowly major change moves in Canada's federal system. Whether this law actually solves the problem will depend on what happens next: whether the regulations are strong, whether funding stays intact through future budgets, and whether the government and First Nations communities work together to make it real.
