What does the Sparrow test evaluate to determine if a limitation on an aboriginal right is justified?

The Sparrow test, formulated in R v. Sparrow, is a critical framework used by Canadian courts to evaluate whether a government action that limits an Aboriginal right is justified under section 35 of the Constitution Act, 1982. This test has three essential components: the government must demonstrate that the limitation on the right is reasonable, consider whether the infringement imposes undue hardship on the rights holder, and analyze whether the limitation respects the means through which the rights are traditionally exercised.

First, the reasonableness aspect evaluates whether the government's action aligns with the objectives of the broader legal framework and the purposes behind protecting Aboriginal rights. It ensures that any limitations do not fundamentally undermine these rights unnecessarily.

Second, the consideration of undue hardship looks at the impact that the limitation has on the Aboriginal group. This involves assessing whether the rights holders suffer significant adverse effects as a result of the limitation, and if the imposition is disproportionate to the goals being pursued.

Lastly, the evaluation of the means of exercising rights refers to maintaining respect for how Indigenous peoples traditionally engage with their rights. It ensures that the manner in which rights are regulated or limited does not suppress the essence of how those rights are expressed.
