How are Senators appointed?

Discover Canada records this in one direct sentence. The guide writes: Senators are appointed by the Governor General on the advice of the Prime Minister and serve until age 75. The mechanism the test wants is therefore by the Governor General on the advice of the Prime Minister.

Both halves of the answer matter. The Governor General formally appoints, but the choice is shaped "on the advice of the Prime Minister" — the same advise-the-Sovereign pattern that Discover Canada uses for the Governor General's own appointment, and for each provincial Lieutenant Governor. So the Prime Minister's advice runs through every level of the constitutional appointment chain.

The Senate sits inside Parliament alongside the elected chamber. Discover Canada writes: "The House of Commons is the representative chamber, made up of members of Parliament elected by the people, traditionally every four years. Senators are appointed by the Governor General on the advice of the Prime Minister and serve until age 75." So the country's two chambers have different sources of authority — election in one, appointment in the other — but together they consider and review every bill before it can become law.

The age-75 retirement is the other distinguishing rule for senators. Discover Canada says senators "serve until age 75," not for a fixed term like the Governor General's five years. So senators tend to serve long, sometimes decades, until reaching the mandatory retirement age — the constitutional structure designed to give the Senate continuity.

The question is testing whether new citizens know how senators get into the Senate. Discover Canada commits to a two-part mechanism: the Governor General appoints, on the advice of the Prime Minister. The right test answer keeps both halves.

The wrong answer choices each pick a different mechanism. Discover Canada never says senators are directly elected by voters; election applies to the House of Commons. The Senate does not appoint itself. The Supreme Court has no role in the appointment process — it is part of the Judicial branch, not Senate selection.
