The Cowichan Decision: Aboriginal Title on Fee Simple Land

On August 7, 2025, the British Columbia Supreme Court released its decision in Cowichan Tribes v. Canada (Attorney General), 2025 BCSC 1490, concluding an unprecedented 11-year trial that stretched 513 trial days . The ruling marks the first time in Canadian history that a court recognized Aboriginal title over lands currently held in fee simple — the strongest form of private property ownership . The decision has triggered appeals from all seven original parties and a bid by a major private landowner to reopen the case, while raising profound questions about the security of land titles across British Columbia.

What the Court Decided

Justice Barbara Young recognized Aboriginal title held by the descendants of the Cowichan Nation — including Cowichan Tribes, Stz’uminus First Nation, Penelakut Tribe, and Halalt First Nation — over approximately 732–740 acres in southeast Richmond on Lulu Island, representing about 40% of the roughly 1,846 acres originally claimed . The title area encompasses residential, agricultural, industrial, and commercial properties, along with roads, foreshore, submerged lands, and flood-protection infrastructure .

The Court determined the land was never lawfully surrendered. Fee simple grants issued by the provincial government between 1871 and 1914 were invalid for two reasons: they violated the Terms of Union under which British Columbia joined Canada, and under the division of powers in the Constitution Act, 1867, only the federal Crown — not the province — had the constitutional authority to extinguish Aboriginal title .

A critical distinction emerged in the treatment of different landowners. The Court declared that fee simple titles and interests held by the federal government and the City of Richmond are "defective and invalid" . However, the Court did not grant a declaration invalidating the fee simple titles of private landowners. Instead, those private titles now co-exist with the underlying Aboriginal title — a legally unprecedented arrangement . The judgment did not resolve how two exclusive rights of use and occupation can operate on the same parcel of land .

The Court also affirmed the Cowichan Nation’s Aboriginal right to fish for food in the south arm of the Fraser River, despite competing claims from the Tsawwassen First Nation and Musqueam Indian Band .

The Appeal Process

The decision was immediately contested. All seven original parties have filed appeals, routing the case to the B.C. Court of Appeal in a process expected to take years, with the Supreme Court of Canada widely expected to hear it eventually .

The Cowichan Nation is appealing because it believes the Court should have recognized Aboriginal title over a larger portion of its claimed territory . Canada, British Columbia, the City of Richmond, the Vancouver Fraser Port Authority, the Tsawwassen First Nation, and the Musqueam Indian Band all filed appeals on various grounds . British Columbia’s Attorney General Niki Sharma stated the province “disagree[s] strongly with the decision” and filed an appeal seeking a stay of implementation, warning the ruling “could have significant unintended consequences for fee simple private property rights in B.C.” .

The Private Landowner Challenge

Private landowners were never formally served or notified during the trial. In 2017, Justice Jennifer Power ruled that private owners did not need to be served, on the basis they could raise arguments in later proceedings . That decision has since drawn sharp criticism.

Montrose Properties, a major private landowner with significant holdings in the claim area — reportedly controlling roughly 120 hectares of industrial property including a Coca-Cola plant and a Canadian Tire depot — filed an application on January 23, 2026, to be added as a party and to ask the BCSC to reopen its decision . Montrose’s president and CEO, Ken Low, said: “As one of many private landowners surprised by the impact of a case that we were not even party to, we have no choice but to take this step” . The company argued that as one of the largest affected private owners, it was never given notice or an opportunity to be heard during the 11-year trial .

Other private landowners are appealing their property value assessments to the Property Assessment Appeal Board, arguing the declaration of Aboriginal title has destroyed their land value .

Implications for Property Rights Law

The ruling rewrites fundamental assumptions about fee simple title in British Columbia. The Court established that the Crown could not constitutionally extinguish Aboriginal title simply by granting fee simple deeds, especially before the entrenchment of Aboriginal rights in section 35 of the Constitution Act, 1982. This reasoning means that any fee simple title in B.C. originating from a provincial Crown grant before 1982 may be legally vulnerable to a future Aboriginal title claim, provided a First Nation can prove exclusive historic occupation .

Legal analysts have pointed to a new era of “co-title” uncertainty. The possibility that Aboriginal title and fee simple ownership could exist simultaneously on the same parcel — something Canadian property law has never addressed — creates acute uncertainty for land-use permitting, municipal taxation, mortgage lending, and title insurance . One case commentary noted the unresolved question: “how can two rights to exclusive use and occupation of land, held by different parties, co-exist?”

The practical consequences are already being felt. Industry observers note the decision creates major questions about the security of fee simple title in B.C., affecting property values, marketability, and the willingness of lenders and insurers to treat land as fully secure collateral .

The Court did not order private fee simple titles invalidated immediately. Instead, it declared that those titles “unjustifiably infringe” on Aboriginal title, and that British Columbia has a duty to negotiate “in relation to reconciliation of Crown-granted fee simple title to third-parties” . The ruling was suspended for 18 months to allow for what the Court called an “orderly transition” and negotiation . The legal status of private land within the declared title area is now unsettled, and future negotiations or court rulings could change the rights of current owners.

Because the Court’s reasoning applies province-wide, the Cowichan precedent could be replicated across British Columbia, potentially affecting thousands of properties . How the B.C. Court of Appeal — and ultimately the Supreme Court of Canada — reconciles the constitutional protection of Aboriginal title with the system of registered, indefeasible fee simple title will determine whether this decision becomes an outlier or permanently reshapes Canadian property law .
