Wildlife law evolves in response to the ecological status of wildlife populations, changing values and societal objectives for wildlife and changes to the domestic and international legal context within which wildlife is managed. Canadian wildlife law has changed significantly since the time of Confederation. This study briefly explores the constitutional framework for and common law sources of Canadian wildlife law. It then develops a series of criteria which distinguished three distinct eras in our wildlife law.
