Constitutional Crossroads: What Mathur v Ontario Means for Climate Policy, Energy and Canadian Law

In this episode of Hearsay, we sit down with Professor Martin Olszynski, Associate Professor and Chair in Energy, Resources and Sustainability at the University of Calgary, to unpack Mathur v Ontario — a groundbreaking climate case at the Ontario Court of Appeal.

The episode explores the Charter arguments at the core of the decision, including the scope of sections 7 and 15, the distinction between positive and negative rights, and the court’s rejection of Ontario’s defence. With implications that reach far beyond provincial borders, this conversation dives into what Mathur means for constitutional climate litigation, energy policy-making, and the broader future of environmental accountability in Canadian politics.
