Learning Goal: I can explain how Canadian courts have interpreted Indigenous and Treaty rights, and I can name at least one landmark court case and what it decided. I can describe a difference between how the Crown and First Nations peoples have understood treaty obligations.
Ron Sparrow fished with a drift net in the Fraser River in 1984. He was a member of the Musqueam Nation in British Columbia. Federal fisheries officers charged him with using a net longer than his licence allowed. Sparrow argued the Musqueam held an Indigenous right to fish that the regulation could not override. In 1990, the Supreme Court of Canada agreed.
Indigenous and Treaty rights do not enforce themselves. For most of Canadian history, the federal government ignored or violated the promises it made in treaties. First Nations communities spent decades in court — at enormous personal and financial cost — fighting governments with far more money and legal power. The four decisions below changed Canadian law.
The Supreme Court ruled that the Musqueam Nation held an Indigenous right to fish, and that the federal government's net-length regulation infringed that right without justification. The Court established two principles that still govern all Indigenous rights cases: governments must interpret Indigenous rights broadly, and governments must justify any restrictions on those rights by proving a valid objective and showing their action respects the Crown's trust relationship with Indigenous peoples. Sparrow was the first Supreme Court decision to interpret Section 35 of the Constitution.
The Gitxsan and Wet'suwet'en peoples claimed Indigenous title over approximately 58,000 square kilometres of land in British Columbia. The Supreme Court ruled that Indigenous title is a right to the land itself, not just to specific uses of it, and that it includes the right to exclusive use and occupation. The Court also ruled that oral history is valid evidence in Canadian courts. Gitxsan and Wet'suwet'en peoples had transmitted detailed accounts of their territory and governance through oral tradition for generations. Canadian courts had previously dismissed oral accounts as unreliable. Delgamuukw overturned that position.
The Province of British Columbia allowed a forestry company to log in Haida territory without consulting the Haida Nation. The Supreme Court established what courts now call the duty to consult: the Crown must consult with First Nations, and where appropriate accommodate them, whenever Crown conduct could affect their Indigenous or treaty rights, even before those rights have been formally proven in court. This decision applies directly to communities in Treaty 4 territory. Before any government or company breaks ground in the Qu'Appelle Valley, it carries a legal obligation to consult the First Nations whose rights the project could affect.
The federal government proposed a winter road through Mikisew Cree traditional territory in northern Alberta. The Mikisew Cree held treaty rights in that area under Treaty 8. The Supreme Court ruled that the Crown had not fulfilled its duty to consult before planning the road, and that treaty promises survived even when governments preferred to act without consultation. This confirmed that the duty to consult applies to treaty rights, not just Indigenous rights. Any government acting on Treaty 4 territory carries the same obligation.
These four decisions share a direction. Courts have consistently found that the Crown's power to act on Indigenous lands is limited by its obligations to First Nations peoples. Those obligations cannot be set aside because they are inconvenient or expensive. They must be honoured.
First Nations communities won these cases against governments with far greater legal resources. The decisions were not gifts. They were the result of decades of litigation by peoples who refused to accept that their rights had disappeared.
Key Idea: Canadian courts have confirmed through decades of decisions that Indigenous and Treaty rights are real, enforceable, and not extinguishable by government convenience. Governments must consult First Nations before acting in ways that could affect those rights. Indigenous oral history is valid evidence. These decisions were won by First Nations communities at significant cost — they were not handed down voluntarily.
