Section 35 of the Constitution Act, 1982, the Supreme Court of Canada has said, protects existing Aboriginal and treaty rights from unjustified infringement at the hands of federal and provincial legislatures and governments. To give meaningful effect to section 35’s protection, we need, therefore, to understand what counts as infringement of such rights and why. The Supreme Court’s own jurisprudence to date on this question, alas, disappoints; it does not withstand close critical scrutiny. This article calls attention to several shortcomings and inconsistencies in that jurisprudence and proposes for initial consideration a more inclusive approach to infringement identification, one that draws a sharper distinction between the infringement and justification inquiries. Adoption of such an approach, however, could have unwelcome substitution effects, prompting cautious courts to be more selective when asked to authenticate future claims of Aboriginal right, more penurious when construing the constitutionally protected scope of particular treaty or Aboriginal rights and/or more generous to governments during the justification inquiry. If the goal is to optimize the protection that Canadian constitutional law affords to treaty and Aboriginal rights, we shall need to be mindful of the interdependence among the authentication, infringement, and justification inquiries, and we shall need to understand much more clearly than we currently do just where the outer limits are beyond which mainstream Canadian law cannot, or will not, countenance Indigenous ways and why.
