Context: A parliamentary system is a system of democratic governance of a state where the executive branch derives its democratic legitimacy from the legislature (parliament) and is also held accountable to that legislature. In a parliamentary system, the head of state is normally a different person from the head of government. This is in contrast to a presidential system in a democracy, where the head of state often is also the head of government, and most importantly, the executive branch does not derive its democratic legitimacy from the legislature., The Conservative Party of Canada, colloquially known as the Tories, is a political party in Canada. It is positioned on the right of the Canadian political spectrum. The party's leader from 2004 to 2015 was Stephen Harper, who served as Prime Minister from 2006 to 2015., Paul Edgar Philippe Martin (born August 28, 1938), also known as Paul Martin Jr., is a Canadian politician who served as the 21st Prime Minister of Canada from December 12, 2003, to February 6, 2006., The Parliament of Canada is the federal legislative branch of Canada, seated at Parliament Hill in the national capital, Ottawa, Ontario. The body consists of the Canadian monarch, represented by a viceroy, the governor general; an upper house: the Senate; and a lower house: the House of Commons. Each element has its own officers and organization. The governor general summons and appoints each of the 105 senators on the advice of the Prime Minister of Canada, while the 338 members of the House of Commonscalled "members of parliament" (MPs)are directly elected by eligible Canadian voters, with each MP representing a single electoral district, commonly referred to as a "riding"., A minority government, or minority cabinet or minority parliament, is a cabinet formed in a parliamentary system when a political party or coalition of parties does not have a majority of overall seats in the parliament. It is sworn into office, with or without the formal support of other parties, to enable a government to be formed. Under such a government, legislation can only be passed with the support of enough other members of the legislature to provide a majority, encouraging multi-partisanship. In bicameral parliaments, the term relates to the situation in chamber whose confidence is considered most crucial to the continuance in office of the government., Stephen Joseph Harper (born April 30, 1959) is a Canadian retired politician who served as the 22nd Prime Minister of Canada, from February 6, 2006 to November 4, 2015. He was the first prime minister to come from the modern Conservative Party of Canada, which was formed by a merger of the Progressive Conservative Party and the Canadian Alliance., The Canadian federal election , 2004 ( more formally , the 38th General Election ) , was held on June 28 , 2004 to elect members of the House of Commons of Canada of the 38th Parliament of Canada . The Liberal government of Prime Minister Paul Martin lost its majority , but was able to form a minority government after the elections . The main opposition party , the newly amalgamated Conservative Party of Canada , improved its position but with a showing below its expectations . On May 23 , 2004 , Governor General Adrienne Clarkson , on the advice of Martin , ordered the dissolution of the House of Commons . Following a 36 - day campaign , voters elected 308 Members of the House of Commons . All three major national parties had changed their leaders since the 2000 election . Earlier the election was widely expected to be a relatively easy romp for Martin to a fourth consecutive Liberal majority government , but early in 2004 Liberal popularity fell sharply due to the sponsorship scandal . Polls started to indicate the possibility of a minority government for the Liberals , or even a minority Conservative government , fuelling speculation of coalitions with the other parties . In the end , the Liberals fared better than the final opinion polls had led them to fear , but well short of a majority . On election day , polling times were arranged to allow results from most provinces to be announced more or less simultaneously , with the exception of Atlantic Canada , whose results were known before the close of polling in other provinces due to the British Columbia Supreme Court 's decision in R. v. Bryan ., The House of Commons of Canada is a component of the Parliament of Canada, along with the Sovereign (represented by the Governor General) and the Senate. The House of Commons chamber is located in the Centre Block of the Parliament Buildings on Parliament Hill in Ottawa., Subject: canadian federal election, Relation: office_contested, Options: (A) governor (B) head of state (C) prime minister (D) prime minister of canada
