Short holding. Canada's legislation recognizing the United Nations Declaration on the Rights of Indigenous Peoples doesn't automatically make every article of that declaration an immediately enforceable rule for a federal regulator. In Canadian Nuclear Laboratories Ltd. v. Kebaowek First Nation, 2026 FCA 174, the Federal Court of Appeal concluded that the Canadian Nuclear Safety Commission had applied the governing Canadian duty to consult when it approved a waste disposal facility at Chalk River. The Court allowed Canadian Nuclear Laboratories' appeal, dismissed Kebaowek's cross appeal and restored the regulatory decision.
The dispute arose from a proposed facility for low level radioactive waste at the Chalk River Laboratories site beside the Ottawa River. The land had been expropriated in the 1940s and used for nuclear activities for decades. Existing arrangements for storing much of the waste didn't meet modern long term containment standards. Canadian Nuclear Laboratories proposed a new near surface disposal facility capable of receiving up to 1,000,000 cubic metres of solid waste. The Commission authorized an amendment to its licence in January 2024, finding the project's environmental risks acceptable with mitigation and concluding that the Crown's duty to consult had been discharged. Kebaowek First Nation, one of the Algonquin Anishinabeg communities whose traditional territory includes the area, disputed the adequacy of that process.
At first instance, the Federal Court accepted that the Commission had failed to consider the declaration and the principle of free, prior and informed consent as a contextual part of its assessment. The judge ordered further consultation directed toward a mutually acceptable arrangement, although she didn't cancel the licence approval. The project proponent appealed that requirement. Kebaowek cross appealed, seeking to have the regulator's decision itself set aside. The dispute before the appellate court was therefore narrower than the full history of Indigenous occupation and nuclear development in the region. It concerned what obligations Parliament's 2021 federal declaration statute added to the regulator's existing legal duties.
Writing for a unanimous panel, Justice Wyman Webb began with the established consultation framework in Haida Nation. The honour of the Crown requires meaningful engagement, and the required depth depends on the strength of the asserted right and the seriousness of a new potential adverse impact. It doesn't impose a universal veto over Crown decisions. On this record, Kebaowek's claimed Aboriginal title area was adjacent to the facility rather than covering the site itself, although the site fell within broader traditional territory. The original taking and long exclusion from the area were serious historical circumstances, but the record hadn't shown new adverse effects beyond those flowing from that earlier taking. The Court placed the current duty near the lower end of the consultation spectrum. It also noted that the lower court had regarded the environmental evidence and the Commission's impact findings as reasonable.
The central statutory question required more than repeating Parliament's recognition of the declaration. The Court examined sections 2 to 7 of the United Nations Declaration on the Rights of Indigenous Peoples Act, including the obligation in section 5 for the Government of Canada to work with Indigenous peoples to bring Canadian laws into alignment with the declaration. The Act contains an implementation framework, an action plan and reporting duties. It doesn't say that declaration provisions prevail over inconsistent Canadian laws immediately. The Court compared that drafting choice with federal legislation implementing international tax conventions, where Parliament has expressly said that the international instrument takes priority in a conflict. It also considered the Supreme Court's 2024 First Nations child and family services reference and British Columbia's Gitxaala appeal. Recognition in domestic law, it reasoned, is an important legislative step, but isn't the same as immediate enactment of each declaration article as an overriding rule.
That distinction mattered for Articles 29(2) and 32(2). The former addresses consent before storage or disposal of hazardous materials on Indigenous lands or territories, while the latter addresses consultation and cooperation directed toward consent for projects affecting Indigenous lands and resources. The Federal Court had treated the proposed disposal facility as triggering a heightened consent process through these provisions. The Court of Appeal held that the federal statute itself hadn't imposed either article as an additional operative requirement on the Commission when it decided this licence. Its reasoning didn't declare that free, prior and informed consent has no significance in Canadian law, or that international standards can never inform a proper interpretation. The holding concerned the particular obligations said to arise directly from this federal implementation statute.
The panel reached a separate conclusion about who must carry out the statute's alignment process. Section 5 assigns that work to the Government of Canada. The nuclear regulator is an agent of the Crown and its licensing decision can trigger the Crown's constitutional duty to consult. That doesn't automatically make it the Government of Canada for every statutory purpose. The Commission has a specific mandate to regulate nuclear materials and safety, while section 5 contemplates broader measures to reconcile Canadian laws with the declaration in cooperation with Indigenous peoples. It was not the Commission's job, when deciding this licence, to conduct that general legislative alignment exercise. The Court also rejected the argument that the Nuclear Safety and Control Act's reference to international obligations independently made this declaration enforceable as a treaty obligation.
Several limits matter for anyone using this decision to assess a future project. The Court didn't finally decide whether the wording about Indigenous lands and territories in Article 29(2) covers land taken decades earlier that isn't part of a current title claim. It noted the different wording of Articles 26 to 29 and the unresolved possibility of separate redress for historical taking. Nor did it settle the federal statute's application to all forms of common law, identify every public body that might count as the Government of Canada under section 5, or pronounce on whether another statutory scheme could independently create stronger consultation rights. The decision should not be read as eliminating duties under section 35 of the Constitution or the honour of the Crown. Those duties were accepted as continuing obligations, with their content assessed against the circumstances and evidence.
The Federal Court of Appeal set aside the earlier Federal Court judgment and dismissed Kebaowek's application for judicial review of the Commission's approval. Canadian Nuclear Laboratories received costs on its appeal, and the underlying Federal Court application was dismissed with costs. Kebaowek's cross appeal was dismissed without costs. The ruling removes the additional consultation process ordered below and leaves the original nuclear licence decision standing. For regulators and businesses, it is a reminder to distinguish existing enforceable consultation obligations from statutory programs for future legal alignment. For Indigenous communities, it also makes the precise geographical scope of asserted rights, evidence of new impacts and the legal source of any claimed additional obligation particularly consequential.
