Climate Goals Clash with Treaty Rights as First Nations Sue Over Carbon Project

EDMONTON, AB – February 19, 2026 – A monumental clash between Canada's climate ambitions and its constitutional obligations to Indigenous peoples has erupted in the courts. Five Alberta First Nations have launched a legal challenge against the federal and provincial governments over a deal to advance what could become the world's largest carbon capture and storage (CCS) project, arguing the agreement was made behind their backs and threatens their lands, water, and way of life.

The lawsuit, brought by Whitefish Lake First Nation #128, Frog Lake Cree Nation, Beaver Lake Cree Nation, Onion Lake Cree Nation, and Kehewin Cree Nation, targets a federal-provincial Memorandum of Understanding (MOU) that paves the way for the Pathways Carbon Capture and Sequestration Project. The Nations contend that for years their attempts to engage with the government on the project's immense risks have been ignored, culminating in a deal that violates their Treaty rights and the principle of free, prior, and informed consent.

A Project of Unprecedented Scale

At the heart of the dispute is the $16.5 billion Pathways project, an initiative spearheaded by the Pathways Alliance, a consortium of Canada’s five largest oil sands producers who represent about 95% of the sector's output. The project is pitched as a cornerstone of the industry's plan to reach net-zero emissions by 2050.

The plan involves capturing millions of tonnes of carbon dioxide from more than 20 different oil sands facilities. The captured CO2 would then be transported via a new 400-kilometer pipeline to a massive underground storage hub near Cold Lake, Alberta. There, it would be injected more than a kilometer deep into a geological formation known as the Basal Cambrian Sandstone, where the proponents claim it will remain permanently sequestered.

This proposed storage hub lies directly within or adjacent to the traditional territories and reserve lands of the five First Nations now taking legal action. They express grave concerns about the unproven nature of storing such vast quantities of CO2 and the potential for catastrophic failure.

"Pathways wants to inject and store carbon under our lands forever. We don't know what it will do to our reserve lands, or the waters, plants, and wildlife on our traditional lands," said Whitefish Lake First Nation #128 Chief Herb Jackson in a statement. "We also don't know what kind of health and safety risks this project poses. We have been asking to work with Canada to understand the impacts of this project for close to three years now, but we've been ignored."

Concerns about CCS technology are not merely hypothetical. Independent scientific bodies have flagged risks including CO2 leakage, which can contaminate groundwater and soil, and induced seismicity, where the pressure of injection triggers earthquakes that could compromise the integrity of the underground storage reservoir.

The Deal that Sparked the Lawsuit

The immediate trigger for the court cases was a Memorandum of Understanding signed in late November 2025 by Alberta Premier Danielle Smith and Prime Minister Mark Carney. The MOU was framed as a "grand bargain" to end years of federal-provincial conflict over energy and climate policy.

Critically, the agreement explicitly links the Pathways CCS project to federal support for a new, privately funded bitumen export pipeline to the British Columbia coast, making the two projects mutually dependent. It also commits both governments to extending financial supports and tax credits for CCS development.

While the MOU mentions Indigenous co-ownership opportunities for the pipeline, it notably does not require Indigenous consent for the projects to proceed. This omission is at the core of the First Nations' legal argument. They allege that after they requested a federal environmental review of the Pathways project in 2024, the government indefinitely suspended the process without response, only to then sign the MOU with Alberta.

"You would never see the world's largest carbon storage project placed beneath a major city without full debate and clear consent," stated Chief Vernon Watchmaker of Kehewin Cree Nation. "Yet something of this scale is being advanced within our Treaty territory... We never ceded or surrendered our lands – our consent is fundamental."

A Test of Treaty Rights and Reconciliation

The First Nations are grounding their challenge in the constitutionally protected rights enshrined in Treaty 6, a historic agreement that governs the relationship between the Crown and the signatory Nations. They argue that the government's duty to consult and accommodate them has been breached, and that for a project of this magnitude and permanence, simple consultation is insufficient.

"Treaty 6 is a living agreement that requires the protection of our lands and waters for future generations," said Chief Pete Chief of Onion Lake Cree Nation. "Decisions to inject and store carbon in our territory cannot be made by governments behind closed doors and without our consent. If our Treaty is not respected, we will defend it in court."

The legal challenge highlights a growing tension in Canadian law and policy between the government's established "duty to consult" and the standard of "free, prior, and informed consent" (FPIC) outlined in the United Nations Declaration on the Rights of Indigenous Peoples, which Canada has adopted into federal law. The Nations argue that FPIC, not mere consultation, is the required standard here.

Some leaders emphasize that their opposition is not to development itself, but to the process that has excluded them. "We want to be clear – Frog Lake supports responsible economic development and we do not necessarily oppose this project," said Chief Greg Desjarlais of Frog Lake Cree Nation. "But it needs to be done in partnership with us – not behind our backs and without our consent."

With no date yet set for a hearing, the future of the multi-billion-dollar Pathways project, and a significant part of Canada's climate strategy, hangs in the balance. The lawsuit represents a critical test case that could redefine the roles of provincial, federal, and Indigenous governments in the approval of major energy projects for decades to come. The outcome will reverberate far beyond Alberta, forcing a national reckoning on whether Canada can pursue its ambitious environmental goals while simultaneously upholding its commitments to reconciliation and the constitutional rights of Indigenous peoples.
