Criminal Law Plenary
This session will explore a set of cases from the Supreme Court of Canada’s 2025 jurisprudence that raise fundamental questions surrounding police and prosecutorial powers, trial procedure, and standards of proof in various dimensions of the criminal process. Panelists will examine key new cases related to section 9 and the power of arrest (R v Carignan, R v Wilson), the intersection of prosecutorial discretion and section 11(b) (R v Varenes), the constitutional status of a presumption of diminished blameworthiness in youth justice (R v IM), and the place of the presumption of innocence and section 11(d) in the prison setting (John Howard).

Federalism’s Frontiers: Still Watertight?
The Supreme Court’s decision in Opsis Airport Services Inc. v. Quebec (Attorney General) largely confirmed the existing caselaw on interjurisdictional immunity. However, this jurisprudence is certainly something of an outlier in the era of cooperative federalism. Our panelists will consider the historical development of the interjurisdictional immunity doctrine, and the looming possibility of future application of the doctrine to protect provincial heads of power.

Text, Liberty, and Constitutional Method After R. v. Kloubakov, 2025 SCC 25
In R. v. Kloubakov, 2025 SCC 25, the Supreme Court upheld key provisions of the Protection of Communities and Exploited Persons Act (PCEPA). The appeal was largely resolved through statutory interpretation. Although framed as purpose-driven, the Court’s reasoning reflects a potentially new emphasis on text as the anchor of interpretation. This discussion will also consider, although the Court declined to do so, liberty-based claims to sell sexual services, and how these have developed in past case law and currently ongoing litigation.

Constitutional Protections for Political Speech
In the much anticipated Ontario (Attorney General) v. Working Families Coalition (Canada) Inc. decision, the Supreme Court of Canada split 5-4 in finding the provisions in Ontario’s Election Finance Act that limit “third party” spending for political advertising in violation of section 3 of the Charter, and insufficiently tailored to be justified in a free and democratic society. The case touches on several timely constitutional issues including the effective participation of citizens in the electoral process, the participation of political parties, unions, civil society organizations, and corporate interests in the information environment surrounding an election, broader questions concerning access to information in a democracy, the status of s.3 in relation to the notwithstanding clause, and the expressive and informational dimensions of political speech.
