The distribution of legislative powers among the various levels of government isa key feature of federalism. To guide this distribution, the Constitution Act, 1867 divides legislative powers between the Parliament of Canada and the provincial legislatures. These powers are set out in sections 91 to 95 of the Constitution Act, 1867. However, simply reading these provisions is not usually enough to determine which level of government has jurisdiction over which area. As new areas emerge and legislative authority becomes increasingly complex, questions remain, notably the following: Which areas fall under the jurisdiction of each level of government? Does a given level of government have the necessary authority to make laws in these areas? Canadian courts are regularly asked to consider these issues and, over time, have established some interpretive principles. The answers, nonetheless, remain complex. This HillStudy focuses on the distribution of legislative powers between Parliament and the provincial legislatures in selected areas. First, it briefly describes the provisions of the Constitution Act, 1867 that concern legislative powers. Second, it examines how certain powers were assigned to the appropriate level of government in light of the interpretive principles established by the courts.
