This special edition of the osgoode hall law journal presents a collection of articles originally delivered at a symposium in 2013 celebrating John McCamus’s 40 years as a professor at Osgoode Hall Law School of York University. The conference might equally have celebrated other milestones in John’s remarkable professional life: forty years—give or take—since his first venture in law reform as a member of a research team; twenty years since his appointment as a member (subsequently Chair) of the Ontario Law Reform Commission; twenty years or so as Chair of the Canadian Civil Liberties Association; twenty years as well since the publication of his monumental work, The Law of Restitution (with the late Peter Maddaugh); ten years since his even more monumental work, The Law of Contracts , appeared; and five years as Chair of Legal Aid Ontario, the logical culmination of his work in the field reaching back to 1996 when he was appointed to head up a review of the province’s legal aid scheme.
