The role of the Supreme Court of Canada as final constitutional arbiter makes this institution a pillar of the Canadian federation. Through its decisions, the Court sets out the features of the constitutional architecture of the country, making its jurisprudence a privileged method of evolution of Canadian federalism. Though, in its recent jurisprudence, the Court appears to be particularly open to the demotic issues that transcend the Canadian constitutional order. Actually, in the decisions rendered in Reference re Supreme Court Act, ss 5 and 6, Reference re Senate Reform and its decision about the firearms registry, the Court develops a jurisprudence in which the asymmetrical and consociational nature of Canadian federalism has singular place. Therefore, making use of the theory of consocialism, we propose here an analysis of these three cases, with the aim to highlight how they contribute to a constitutional jurisprudence that is better adapted to the multinational nature of the country. More generally, this demonstration will also be the occasion to observe the limits of the jurisprudence as the principal evolution mode of the Canadian Constitution.
