Section 7 of the Canadian Charter of Rights and Freedoms protects the right to life, liberty and security of the person, and guarantees that these rights cannot be deprived except in accordance with the principles of fundamental justice. But what do those principles mean, and how do they shape constitutional litigation? In this episode of Charter: A Course, host Cheryl Milne speaks with Professor Hamish Stewart of the University of Toronto Henry N.R. Jackman Faculty of Law about the development and application of the principles of fundamental justice under Section 7. They explore the distinction between procedural and substantive principles, the evolution of the Section 7 framework, and the role of arbitrariness, overbreadth and gross disproportionality in Charter analysis. In the Practice Corner, Gerald Chan, a partner at Stockwoods LLP, discusses the importance of evidence in Section 7 litigation. Drawing on his experience in constitutional law cases, he considers the role of first-hand and expert evidence, the challenges of building a strong evidentiary record, and the way factual findings can shape the outcome of Charter challenges.

Ontario (Attorney General). The Ontario Superior Court had found the legislation unconstitutional in 2025 ONSC 4397, but that decision was subsequently overturned by the Court of Appeal in 2026 ONCA 582, released August 14, 2026. Gerald Chan’s later Practice Corner discussion reflects the Court of Appeal’s decision. Cases Discussed in this episode Foundational Section 7 and procedural fairness decisions: R. v. Sault Ste.
