Section 35 Aboriginal and treaty rights are not part of the Charter of Rights and Freedoms, so they are “not subject to [section] 1 of the nor to legislative override under [section] 33.” Section 1 of the Charter allows governments to justifiably limit a Charter right, and section 33 establishes the notwithstanding clause, which allows governments to pass laws “notwithstanding” their impact on certain Charter rights.
Although neither section 1 nor section 33 may be invoked to override or diminish Aboriginal or treaty rights, Aboriginal and treaty rights are not absolute. Under certain circumstances, the Crown may limit or infringe Aboriginal or treaty rights. In R v Sparrow, the Supreme Court of Canada established a two-step test — the Sparrow test — for justifying an infringement of an Aboriginal right. The test is highly contextual, which means that the standard of justification varies with the facts of each case.
The Sparrow test comprises two steps:
If a court finds that the infringement is justified, the law remains valid and applicable to that Aboriginal group. If not, the impugned law would be found to be contrary to section 35(1) of the Constitution Act, 1982 and of no force and effect as it relates to the Aboriginal group whose rights were infringed.
The courts have applied the Sparrow test to justify infringing Métis rights and treaty rights, and as the basis of the test for infringing Aboriginal title. In R v Côté, the Supreme Court of Canada confirmed that the Sparrow test applies equally to federal and provincial laws.

The Court clarifies that objectives which are “compelling and substantial” are “those directed at either the recognition of the prior occupation of North America by [A]boriginal peoples or … at the reconciliation of [A]boriginal prior occupation with the assertion of the sovereignty of the Crown” (para 72). The pursuit of economic and regional fairness may satisfy this standard under the right circumstances (para 75).
 Ibid at 1114. See also Delgamuukw v British Columbia, 1997 CanLII 302 (SCC) at paras 161-164 . Courts must consider what form the Crown’s fiduciary duty takes, and what the Crown must do in its fiduciary capacity to justify infringing the protected right. The degree of scrutiny required must vary according to the nature of the Aboriginal right at issue and the form that the Crown’s fiduciary duty takes.
