In 1850, the respondents, the Anishinaabe of the northern shores of Lakes Huron and Superior, entered into two treaties with the Crown: the Robinson-Huron Treaty and the Robinson-Superior Treaty (“Treaties”). The Treaties provided for cessation of a vast territory in northern Ontario, and for payment, in perpetuity, of an annuity to the Anishinaabe. The initial agreed-upon sum was paid and an Order-in-Council declared them ratified and confirmed. In 1875, the annuity was increased to $4 (£1) per person, and, in 1877, the Huron and Superior chiefs petitioned successfully for arrears on the increase since the conditions for increasing the annuity had been met long before the increase. The annuity has not changed since.

The Huron respondents initiated an action against Canada and Ontario seeking declaratory and compensatory relief related to the interpretation, implementation and alleged breach of the annuity provisions in the Robinson-Huron Treaty; the Superior respondents made the same claims under the Robinson-Superior Treaty. The actions were tried together, split into three stages. At Stage One, the Treaties were interpreted, at Stage Two, the defences of Crown immunity and limitations were addressed, and, at Stage Three, the remaining issues (inter alia, damages and the allocation of liability) stood to be addressed. This appeal relates to Stages One and Two. Stage Three of the trial commenced in February 2023, but a settlement of that stage was reached.
