Willms & Shier Environmental Law Moot

The Willms & Shier Environmental Law Moot is a moot court competition open to all Canadian law schools. A partnership of Osgoode Hall Law School and Willms & Shier Environmental Lawyers LLP, it is the first and only national moot court competition devoted to environmental law. Its goal is to promote awareness of the growing role of environmental issues in contemporary legal practice and public life, while enhancing law students’ written and oral advocacy skills. Unlike most moot courts, students must argue both sides of the case. The competition takes the form of an appeal before a Canadian court of last resort, bringing together law students, judges, leading lawyers, and legal academics to explore cutting- edge environmental law issues.
