Parliament has passed Bill C-37, the First Nations Clean Water Act, establishing a federal legislative framework to secure long-term access to safe drinking water in First Nations communities across Canada.

The legislation arrives after years of administrative effort under Indigenous Services Canada that produced measurable but incomplete results. ISC's World Water Day statement recorded 144 long-term drinking water advisories lifted as of March 2024. By late July 2024, ISC reported 70 per cent fewer long-term advisories than had been in place in 2015 — progress built nation by nation, often through capital upgrades to aging treatment infrastructure. English River First Nation lifted its advisory in November 2024 following water treatment upgrades, one of the later communities to cross that threshold.

That record of incremental gains is precisely the context Bill C-37 is designed to move beyond. Advisories lifted through capital investment are vulnerable to recurrence if the underlying governance, operations and maintenance structures are not durable. The previous regime — largely driven by funding agreements and ISC directives rather than enforceable legal rights — left communities with limited recourse when service standards slipped or capital timelines stretched. Bill C-37 creates a statutory baseline.

What the Legislation Does

The Act establishes enforceable water quality standards applicable to First Nations public water systems, replacing the patchwork of departmental commitments with justiciable obligations. It creates a rights-based framework under which First Nations can hold the Crown accountable for failures in service rather than relying solely on political escalation or litigation under broader constitutional provisions.

Critically, the legislation addresses the jurisdictional gap that made progress so uneven. Provinces regulate municipal water systems under their own frameworks; First Nations communities on reserve have historically operated in a separate, under-resourced regime. Bill C-37 does not transfer jurisdiction to the provinces — it creates a parallel federal standard with First Nations governance structures at its centre. Band councils and First Nations governments gain formal authority over water system oversight within their territories, backed by federal funding obligations encoded in statute rather than subject to annual appropriations cycles alone.

Budget 2025 included measures to strengthen First Nations infrastructure financing and access to clean water, providing the fiscal architecture that Bill C-37's operational requirements will draw on. The sequencing — legislation following budget commitments — is deliberate; it ties appropriated resources to statutory duties, hardening both against future erosion.

Governance Architecture and Remaining Questions

The Act's effectiveness will turn substantially on implementation detail: the regulations that set specific technical standards, the dispute resolution mechanisms available to communities, and whether the federal funding commitments survive future budget cycles intact. Statutory rights create legal leverage, but litigation is an imperfect substitute for adequately capitalized infrastructure programs.

There is also the question of transition for communities still under advisory. Roughly 30 per cent of the 2015 advisory load remained unresolved as of mid-2024. Bill C-37 does not automatically resolve those situations — it changes the legal standing of the communities affected and the obligations on the federal Crown going forward. The pace of resolution will depend on regulatory timelines and capital deployment, not the Act's passage alone.

First Nations organizations have welcomed the rights-based framing while signalling that scrutiny of the regulatory instruments will be close. The distinction between a framework Act and its subordinate regulations matters here: the principles are in the statute, but the binding specifics — treatment standards, inspection regimes, funding formulas — will be set by order-in-council processes that receive far less parliamentary attention.

For practitioners and officials on both sides of this file, the operational shift is real. ISC's role moves from grant administrator to compliance partner under a statutory mandate. That is a structural change in the relationship, one that affects how departmental officials account for their work and how First Nations governments can engage federal processes when commitments fall short.

The broader policy arc — from the 2015 Liberal election commitment to lift all advisories, through successive budget cycles, through the 2024 Fall Economic Statement, to legislation in 2026 — illustrates how long it takes to translate political will into durable legal architecture in the Canadian federal system. Whether the architecture holds is a question of regulation, funding and implementation that will play out over years, not a single parliamentary session.
