In a federal election, Canadians vote for:

Discover Canada records this in one direct sentence about the House of Commons. The guide writes: The House of Commons is the representative chamber, made up of members of Parliament elected by the people, traditionally every four years. The named target of federal voting is therefore members of the House of Commons (Members of Parliament).

Three precise commitments. Discover Canada commits federal voting to THREE specific facts: (1) the chamber is the House of Commons; (2) members are elected by the people; (3) elections are held traditionally every four years. So the source pinpoints the elected chamber, the popular-election rule, and the customary timing.

Each electoral district elects one MP. Discover Canada commits the per-district rule to a specific direct sentence: "The citizens in each electoral district elect one MP who sits in the House of Commons to represent them, as well as all Canadians." So in each riding, voters choose ONE MP — and the winning candidate represents both the local district and the country as a whole. "The candidate who receives the most votes becomes the MP for that electoral district." So the federal election is fundamentally an election of MPs, riding by riding.

The Senate and other officers are filled differently. Discover Canada commits non-elected federal officers to specific named processes: "Senators are appointed by the Governor General on the advice of the Prime Minister and serve until age 75." So Senators are NOT elected — they are appointed. The "Sovereign is represented in Canada by the Governor General, who is appointed by the Sovereign on the advice of the Prime Minister, usually for five years." So the Governor General is also NOT elected — also appointed. The Prime Minister is the leader of the political party that wins the most seats in the House of Commons; the Prime Minister is therefore not directly elected by the public, but indirectly chosen through the federal election. "Ordinarily, after an election, the leader of the political party with the most seats in the House of Commons is invited by the Governor General to form the government. After being appointed by the Governor General, the leader of this party becomes the Prime Minister." So when the test asks who Canadians vote for in a federal election, the source-precise answer is members of the House of Commons.

The question is testing whether new citizens know what they vote for in a federal election. Discover Canada commits to one named target: members of the House of Commons (MPs). The right test answer matches that.

The wrong answer choices each substitute a different officer. The first choice — the Prime Minister — is not directly elected; the Prime Minister is the leader of the party that wins the most seats. The second choice — a Senator — describes appointed positions, not elected ones. The fourth choice — the Governor General — is also appointed, not elected. Only members of the House of Commons — the source's exact named target of federal voting — match.
