Parliament Hill in Canada's capital city, Ottawa
Canada has a parliamentary system within the context of a constitutional monarchy, the monarchy of Canada being the foundation of the executive, legislative, and judicial branches. The sovereign is Queen Elizabeth II, who also serves as head of state of 15 other Commonwealth countries and each of Canada's ten provinces. As such, the Queen's representative, the Governor General of Canada (at present David Lloyd Johnston), carries out most of the federal royal duties in Canada.
The direct participation of the royal and viceroyal figures in areas of governance is limited. In practice, their use of the executive powers is directed by the Cabinet, a committee of ministers of the Crown responsible to the elected House of Commons and chosen and headed by the Prime Minister of Canada (at present Stephen Harper), the head of government. The governor general or monarch may, though, in certain crisis situations exercise their power without ministerial advice. To ensure the stability of government, the governor general will usually appoint as prime minister the person who is the current leader of the political party that can obtain the confidence of a plurality in the House of Commons. The Prime Minister's Office (PMO) is thus one of the most powerful institutions in government, initiating most legislation for parliamentary approval and selecting for appointment by the Crown, besides the aforementioned, the governor general, lieutenant governors, senators, federal court judges, and heads of Crown corporations and government agencies. The leader of the party with the second-most seats usually becomes the Leader of Her Majesty's Loyal Opposition (presently Thomas Mulcair) and is part of an adversarial parliamentary system intended to keep the government in check.

Each of the 308 members of parliament in the House of Commons is elected by simple plurality in an electoral district or riding. General elections must be called by the governor general, either on the advice of the prime minister, within four years of the previous election, or if the government loses a confidence vote in the House. The 105 members of the Senate, whose seats are apportioned on a regional basis, serve until age 75. Five parties had representatives elected to the federal parliament in the 2011 elections: the Conservative Party of Canada (governing party), the New Democratic Party (the Official Opposition), the Liberal Party of Canada, the Bloc Québécois, and the Green Party of Canada. The list of historical parties with elected representation is substantial.
Canada's federal structure divides government responsibilities between the federal government and the ten provinces. Provincial legislatures are unicameral and operate in parliamentary fashion similar to the House of Commons. Canada's three territories also have legislatures, but these are not sovereign and have fewer constitutional responsibilities than the provinces. The territorial legislatures also differ structurally from their provincial counterparts.
Law
Main article: Law of Canada
The Constitution of Canada is the supreme law of the country, and consists of written text and unwritten conventions. The Constitution Act, 1867 (known as the British North America Act prior to 1982), affirmed governance based on parliamentary precedent and divided powers between the federal and provincial governments. The Statute of Westminster 1931 granted full autonomy and the Constitution Act, 1982, ended all legislative ties to the UK, as well as adding a constitutional amending formula and the Canadian Charter of Rights and Freedoms. The Charter guarantees basic rights and freedoms that usually cannot be over-ridden by any government—though a notwithstanding clause allows the federal parliament and provincial legislatures to override certain sections of the Charter for a period of five years.

Although not without conflict, European Canadians' early interactions with First Nations and Inuit populations were relatively peaceful. The Crown and Aboriginal peoples began interactions during the European colonialization period. The Indian Act, various treaties and case laws were established to mediate relations between Europeans and native peoples. Most notably, a series of eleven treaties known as the Numbered Treaties were signed between Aboriginals in Canada and the reigning Monarch of Canada between 1871 and 1921. These treaties are agreements with the Canadian Crown-in-Council, administered by Canadian Aboriginal law, and overseen by the Minister of Aboriginal Affairs and Northern Development. The role of the treaties and the rights they support were reaffirmed by Section Thirty-five of the Constitution Act, 1982. These rights may include provision of services such as health care, and exemption from taxation. The legal and policy framework within which Canada and First Nations operate was further formalized in 2005, through the First Nations–Federal Crown Political Accord.
The Supreme Court of Canada in Ottawa, west of Parliament Hill
Canada's judiciary plays an important role in interpreting laws and has the power to strike down Acts of Parliament that violate the constitution. The Supreme Court of Canada is the highest court and final arbiter and has been led since 2000 by the Chief Justice Beverley McLachlin (the first female Chief Justice). Its nine members are appointed by the governor general on the advice of the prime minister and minister of justice. All judges at the superior and appellate levels are appointed after consultation with nongovernmental legal bodies. The federal Cabinet also appoints justices to superior courts in the provincial and territorial jurisdictions.
Common law prevails everywhere except in Quebec, where civil law predominates. Criminal law is solely a federal responsibility and is uniform throughout Canada. Law enforcement, including criminal courts, is officially a provincial responsibility, conducted by provincial and municipal police forces. However, in most rural areas and some urban areas, policing responsibilities are contracted to the federal Royal Canadian Mounted Police.
Foreign relations and military

Canada currently employs a professional, volunteer military force of 65,000 regular personnel and approximately 53,000 reserve personnel, including supplementary reserves and civilian employees. The unified Canadian Forces (CF) comprise the Canadian Army, Royal Canadian Navy, and Royal Canadian Air Force. In 2011, Canada's military expenditure totalled approximately C$24.5 billion.
Canada and the United States share the world's longest undefended border, co-operate on military campaigns and exercises, and are each other's largest trading partner. Canada nevertheless has an independent foreign policy, most notably maintaining full relations with Cuba and declining to officially participate in the 2003 invasion of Iraq. Canada also maintains historic ties to the United Kingdom and France and to other former British and French colonies through Canada's membership in the Commonwealth of Nations and the Francophonie. Canada is noted for having a positive relationship with the Netherlands, owing, in part, to its contribution to the Dutch liberation during World War II.
Canada's strong attachment to the British Empire and Commonwealth led to major participation in British military efforts in the Second Boer War, World War I and World War II. Since then, Canada has been an advocate for multilateralism, making efforts to resolve global issues in collaboration with other nations. Canada was a founding member of the United Nations in 1945 and of NATO in 1949. During the Cold War, Canada was a major contributor to UN forces in the Korean War and founded the North American Aerospace Defense Command (NORAD) in co-operation with the United States to defend against potential aerial attacks from the Soviet Union.

During the Suez Crisis of 1956, future Prime Minister Lester B. Pearson eased tensions by proposing the inception of the United Nations Peacekeeping Force, for which he was awarded the 1957 Nobel Peace Prize. As this was the first UN peacekeeping mission, Pearson is often credited as the inventor of the concept. Canada has since served in 50 peacekeeping missions, including every UN peacekeeping effort until 1989, and has since maintained forces in international missions in Rwanda, the former Yugoslavia, and elsewhere; Canada has sometimes faced controversy over its involvement in foreign countries, notably in the 1993 Somalia Affair.
Canada joined the Organization of American States (OAS) in 1990 and hosted the OAS General Assembly in Windsor, Ontario, in June 2000 and the third Summit of the Americas in Quebec City in April 2001. Canada seeks to expand its ties to Pacific Rim economies through membership in the Asia-Pacific Economic Cooperation forum (APEC).

In 2001, Canada deployed troops to Afghanistan as part of the US stabilization force and the UN-authorized, NATO-led International Security Assistance Force. Starting in July 2011, Canada began withdrawing its troops from Afghanistan. In all, Canada lost 158 soldiers, one diplomat, two aid workers, and one journalist during the mission, which cost approximately C$11.3 billion.
In February 2007, Canada, Italy, the United Kingdom, Norway, and Russia announced their joint commitment to a $1.5-billion project to help develop vaccines for developing nations, and called on other countries to join them. In August 2007, Canada's territorial claims in the Arctic were challenged after a Russian underwater expedition to the North Pole; Canada has considered that area to be sovereign territory since 1925. Between March and October 2011, Canadian forces participated in a UN-mandated NATO intervention into the 2011 Libyan civil war.
Provinces and territories
Main article: Provinces and territories of Canada
See also: Canadian federalism
Canada is a federation composed of ten provinces and three territories. In turn, these may be grouped into four main regions: Western Canada, Central Canada, Atlantic Canada, and Northern Canada ("Eastern Canada" refers to Central Canada and Atlantic Canada together). Provinces have more autonomy than territories, having responsibility for social programs such as health care, education, and welfare. Together, the provinces collect more revenue than the federal government, an almost unique structure among federations in the world. Using its spending powers, the federal government can initiate national policies in provincial areas, such as the Canada Health Act; the provinces can opt out of these, but rarely do so in practice. Equalization payments are made by the federal government to ensure that reasonably uniform standards of services and taxation are kept between the richer and poorer provinces.
