The federal political parties in the House of Commons are led by individuals who guide the party's policies and strategies. Major parties include the Liberal Party, the Conservative Party, and others such as the NDP and Bloc Québécois.
Step-by-step explanation:
The question asks to name all the federal political parties in the House of Commons and their leaders. As of the knowledge cutoff in 2023, the Canadian House of Commons includes several major political parties. The largest parties, historically, have been the Liberal Party and the Conservative Party, both of which have undergone changes in leadership over the years. In addition, there are smaller parties with representation such as the Bloc Québécois, the New Democratic Party (NDP), and the Green Party of Canada. Each party is led by a leader who is often the party's candidate for Prime Minister in federal elections. The leaders are responsible for guiding their party's legislative agenda, working with party whips to ensure members vote according to the party line, and acting as the face of the party to the public and the media.
