Canadian federalism is one of the three pillars of the constitutional order, along with responsible government and the Canadian Charter of Rights and Freedoms. It means that Canada has two distinct jurisdictions of political authority: on the one hand, the central Canadian Parliament and, on the other hand, legislative assemblies in the ten provinces. The Federal Parliament and the legislative assemblies of the Provinces are sovereign with respect to certain areas of legislative authority. A few subjects are shared.The three territories are creations of the Federal Parliament and exercise delegated power and not sovereign power. The United Kingdom did not follow this model when Confederation was realized, making Canada different from its mother country in this respect.
