1906: Shortening senators’ terms to the life of three Parliaments is debated in the House of Commons.
1915: The Western provinces are given a block of 24 senators, or six each.
1920s: The Progressive Party of Canada (later the Co-operative Commonwealth Federation and then the New Democratic Party) propose abolishing the Senate. It remains an official NDP position to this day.

1956: In the middle of a nearly five-decade span in which the Liberal party holds a Senate majority, the upper house becomes as unbalanced as it’s ever been. With only five Conservatives and 76 Liberals, Louis St. Laurent, the Liberal prime minister at the time, appoints a Conservative senator out of pity.

1984-1985: Despite reports from one joint committee, one select special committee and one royal commission, a wily Senate remains unreformed.
1987: The Meech Lake Accord is negotiated. Senate reform at last!
