Legal Philosophy in Canada
The Hart–Dworkin Debate and Canadian Jurisprudence
Canadian legal philosophy has been profoundly shaped by the international debate between H.L.A. Hart’s legal positivism and Ronald Dworkin’s interpretive theory. Hart’s concept of law as a system of primary and secondary rules — whose validity is determined by a rule of recognition — found resonance among Canadian scholars drawn to its analytical rigour and its separation of law and morality. Dworkin, by contrast, argued that law includes not only rules but also principles that derive their force from the moral fabric of the political community, and that adjudication is a fundamentally interpretive exercise aimed at presenting the legal record in its “best light.”
In Canada, this debate acquired distinctive urgency following the entrenchment of the Canadian Charter of Rights and Freedoms in 1982. The Charter gave Canadian courts the power to strike down legislation inconsistent with enumerated rights and freedoms, transforming the judiciary into a forum of constitutional principle. Dworkin’s theory — particularly his claim that constitutional adjudication involves moral interpretation of abstract provisions like “freedom of expression” or “equality” — resonated strongly with Canadian jurists. The Supreme Court of Canada’s adoption of purposive interpretation in R. v. Big M Drug Mart, [1985] 1 SCR 295, and the proportionality framework in R. v. Oakes, [1986] 1 SCR 103, represent a distinctly Canadian synthesis of Dworkinian interpretive methodology and legal positivist constraint.
Canadian Legal Theorists
Several Canadian jurists have made lasting contributions to legal philosophy. Bora Laskin, who served as Chief Justice of Canada from 1973 to 1984, was a formative influence on Canadian constitutional thought, advocating for a robust conception of judicial review and the recognition of implied rights. Pierre Trudeau’s legal philosophy, though primarily expressed through his political career, was shaped by his engagement with civil libertarian thought and his suspicion of collective rights that might override individual freedoms — positions evident in the design of the Charter and the War Measures Act debates.
Brian Slattery developed a distinctive theory of generative constitutionalism, arguing that Canada’s constitution encompasses not only the written text but also the unwritten norms that emerge from the historical relationship between Indigenous peoples and the Crown. Slattery’s work has been instrumental in the recognition of Aboriginal title and rights under s. 35 of the Constitution Act, 1982, and in the theorization of the honour of the Crown as a constitutional principle. Gerald Gall contributed foundational texts on Canadian legal method and the sociology of law, while Jean-Guy Cardinal and the Quebec civilian tradition maintained a distinct philosophical orientation rooted in continental jurisprudence and the French civil code.
The Charter Values Approach
The term “Charter values” denotes the proposition that the values underlying the Charter — equality, human dignity, freedom of expression, democracy — ought to inform the interpretation and development of the common law. In R.W.D.S.U. v. Pepsi-Cola Canada Beverages, 2002 SCC 8, [2002] 1 SCR 156, the Supreme Court held that freedom of expression under s. 2(b) should guide the development of the common law of picketing. In Hill v. Church of Scientology of Toronto, [1995] 2 SCR 1130, however, the Court declined to reformulate the common law of defamation to align with Charter values, finding that the existing balance adequately protected free expression. More recently, in Ward v. Quebec (Commission des droits de la personne), 2021 SCC 43, the Court held that the common law defence of honest belief in the context of discrimination must be assessed in light of Charter equality values.
The Charter values debate is philosophically significant because it raises foundational questions about the relationship between written constitutional text, judicial interpretation, and legislative supremacy. Critics argue that importing Charter values into private law amounts to an indirect application of the Charter beyond its intended scope; proponents contend that the common law must evolve consistently with the fundamental values of the constitutional order.
Unwritten Constitutional Principles
In Reference re Secession of Quebec, [1998] 2 SCR 217, the Supreme Court of Canada identified four unwritten constitutional principles: federalism, democracy, constitutionalism and the rule of law, and protection of minorities. These principles, the Court held, are not merely descriptive but are legally binding and inform the interpretation of the written constitution. The Secession Reference is a landmark in Canadian constitutional philosophy, embodying a conception of the constitution as a living tree that includes both textual provisions and implied commitments.
The recognition of unwritten principles has generated substantial philosophical commentary. For positivists, it poses a challenge to the idea that law must be traceable to a determinate rule of recognition. For natural law theorists, it vindicates the claim that a legal system necessarily incorporates moral standards. For Dworkinian interpretivists, it exemplifies the method of constructive interpretation — giving the legal record its best justification by making explicit the principles that best explain and justify the constitutional order.
Indigenous Legal Philosophies
A distinctive feature of Canadian legal philosophy is the growing recognition of Indigenous legal traditions as autonomous normative systems. The work of John Borrows (Anishinaabe), Gordon Christie (Inuit), and Val Napoleon (Cree) has developed theoretical frameworks for understanding Indigenous law as a third legal tradition alongside the common law and civil law. These scholars argue that Indigenous legal orders are not merely sources of customary rights but are complete legal systems with their own internal logics, methods of reasoning, dispute resolution mechanisms, and constitutional principles. The Truth and Reconciliation Commission of Canada (2015) and the United Nations Declaration on the Rights of Indigenous Peoples (UNDRIP), implemented through the United Nations Declaration on the Rights of Indigenous Peoples Act, SC 2021, c 14, have given legal and political impetus to the recognition of Indigenous legal orders.
Legal Pluralism, Feminist Legal Theory, and Quebec Civil Law
Canada is a bijural state: Quebec operates a civil law system for private law matters, rooted in the French civilian tradition and codified in the Civil Code of Québec, while the rest of Canada follows the common law. This dualism has produced a rich tradition of comparative legal philosophy in Quebec, drawing from French, German, and Italian jurisprudence, with scholars such as Jean Beetz, Marie-France Bureau, and Sylvio Normand exploring the interface between civilian and common law reasoning.
Feminist legal theory has been a vibrant force in Canadian legal philosophy. Influential theorists — including Catharine MacKinnon, whose work has been taken up extensively in Canadian equality jurisprudence, and Canadian scholars such as Dianne Pothier, Sheila McIntyre, and Beverley Baines — have interrogated the gendered structures of law, the limitations of formal equality, and the potential of substantive equality under s. 15 of the Charter. Canadian courts have been notably receptive to feminist arguments, particularly in the areas of sexual assault law reform, pay equity, and reproductive rights.
Legal pluralism — the recognition that multiple normative orders coexist within a single legal space — is a recurring theme in Canadian legal philosophy. It emerges in the interaction of common law and civil law, in the coexistence of state and Indigenous legal orders, in the regulatory authority of professional and religious tribunals, and in the transnational norms that influence Canadian adjudication. Contemporary Canadian legal philosophy thus resists a monistic account of law, embracing instead a conception of the legal order as a field of overlapping, interacting, and sometimes conflicting normative systems.
