Canadians vote in elections for the people they want to represent them in the House of Commons. In each election, voters may relect the same members of the House of Commons or choose new ones. Members of the House of Commons are also known as members of Parliament or MPs. Under legislation passed by Parliament, federal elections must be held on the third Monday in October every four years following the most recent general election. The Prime Minister may ask the Governor General to call an earlier election. Canada is divided into 308 electoral districts, also known as ridings or constituencies. An electoral district is a geographical area represented by a member of Parliament (MP). The citizens in each electoral district elect one MP who sits in the House of Commons to represent them, as well as all Canadians.
