The leader of the government in the House of Commons (), more commonly known as the government house leader, is the Cabinet minister responsible for planning and managing the government's legislative program in the House of Commons of Canada. Despite the name of the position it does not refer to the prime minister of Canada, who is the head of government. History From 1867 until World War II, prime ministers took upon themselves the responsibilities of being leader of the government in the House of Commons, organizing and coordinating House of Commons business with the other parties. The expansion of government responsibilities during the war led to Prime Minister William Lyon Mackenzie King deciding to delegate the House leadership to one of his ministers. In 1946, the position of government house leader was formally recognized. In 1968, Prime Minister Pierre Trudeau designated the government house leader as president of the Queen's Privy Council for Canada. Under Prime Minister Brian Mulroney, the roles of government house leader and president of the Privy Council were separated in 1989. Under Mulroney and his successors, the position of house leader would often be held by someone who was named a minister of state without any portfolio responsibilities specified. Since 2003, this minister of state status has been obscured in all but the most official circumstances by the use of a "Leader of the Government in the House of Commons" style in its place. Prime Minister Paul Martin's first House Leader, Jacques Saada was also the minister responsible for democratic reform; however, with the election of a minority government in the 2004 election, Martin appointed Tony Valeri to the position of leader of the government in the House of Commons with no additional responsibilities. List of officeholders Until 2005, the position of government house leader was not technically a cabinet-level post, but rather a parliamentary office, so to qualify for cabinet membership, an individual had to be named to cabinet in some other capacity. For a time, with the position having evolved into a full-time job, government house leaders have been named to cabinet as ministers of state with no portfolio specified. The Martin government created these positions so that the minister of state title is effectively invisible. An amendment to the Salaries Act made this unnecessary by listing the government house leader as a minister. Key: 1. The Turner Ministry never convened the House,
