This article explores a very specific kind of legal research - finding the intent of a legislature or parliament. Following a review of the history of legislative intent in Canadian courts, the exclusionary rule and an important Canadian case, Rizzo & Rizzo Shoes Ltd, the authors explore what developments in this area of law, statutory interpretation and, legislative intent research, might mean for parliamentary and legislative libraries in Canada. Based on research for their forthcoming Irwin Law book Researching Legislative Intent: A Practical Guide, this revised article was first presented to the Association of Parliamentary Libraries in Canada/ L�Association des bibliothèques parlementaires au Canada (APLIC/ABPAC) on July 4, 2013, in Ottawa, Ontario.
