The Canadian Charter of Rights and Freedoms (Charte canadienne des droits et libertés), often simply referred to as the Charter in Canada, is a bill of rights entrenched in the Constitution of Canada, forming the first part of the Constitution Act, 1982. The Charter guarantees certain political rights to Canadian citizens and civil rights of everyone in Canada from the policies and actions of all governments in Canada. It is designed to unify Canadians around a set of principles that embody those rights. The Charter was proclaimed in force by Queen Elizabeth II of Canada on April 17, 1982, as part of the Constitution Act, 1982.
The Charter was preceded by the Canadian Bill of Rights, enacted in 1960, which was a federal statute rather than a constitutional document. As a federal statute, the Bill of Rights could be amended through the ordinary legislative process and had no application to provincial laws. The Supreme Court of Canada also narrowly interpreted the Bill of Rights, showing reluctance to declare laws inoperative. The relative ineffectiveness of the Canadian Bill of Rights motivated many to improve rights protections in Canada. The movement for human rights and freedoms that emerged after World War II also wanted to entrench the principles enunciated in the Universal Declaration of Human Rights. The British Parliament formally enacted the Charter as a part of the Canada Act 1982 at the request of the Parliament of Canada in 1982, the result of the efforts of the government of Prime Minister Pierre Trudeau.
The Charter greatly expanded the scope of judicial review, because the Charter is more explicit with respect to the guarantee of rights and the role of judges in enforcing them than was the Canadian Bill of Rights. Canadian courts, when confronted with violations of Charter rights, have struck down unconstitutional federal and provincial statutes and regulations or parts of statutes and regulations, as they did when Canadian case law was primarily concerned with resolving issues of federalism.
