The Senate is the upper house of Canada's Parliament, consisting of 105 senators appointed by the Governor General on the Prime Minister's advice. The Senate reviews legislation passed by the House of Commons, proposes amendments, and conducts studies on policy issues. Senators are appointed regionally—24 each from Ontario, Quebec, the Maritimes, and Western Canada, plus 6 from Newfoundland and Labrador, and 1 each from the territories. Senators serve until age 75 (previously for life). Senate reform has been debated for decades, with proposals ranging from abolition to an elected Senate. Recent changes under the Independent Advisory Board have aimed to make appointments less partisan.
