How often are members of the House of Commons elected?

Discover Canada records this in one direct sentence. 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 interval the test wants is therefore every four years.

The qualifier "traditionally" matters. Discover Canada uses it deliberately — elections can happen sooner if the government loses the confidence of the House. The guide describes the principle elsewhere: "Cabinet ministers are responsible to the elected representatives, which means they must retain the 'confidence of the House' and have to resign if they are defeated in a non-confidence vote." So a Parliament's life can be cut short, but the standard interval is every four years.

Four-year terms apply to the elected House only. Discover Canada writes the contrast in the same paragraph: "Senators are appointed by the Governor General on the advice of the Prime Minister and serve until age 75." Senators do not face elections at all. So in Parliament's two chambers, only the House of Commons has scheduled elections, and the schedule is roughly every four years.

The wider responsibility behind those elections is also in the guide. Discover Canada says "in Canada's parliamentary democracy, the people elect members to the House of Commons in Ottawa and to the provincial and territorial legislatures. These representatives are responsible for passing laws, approving and monitoring expenditures, and keeping the government accountable." So the four-year interval is not just about timing — it is the regular renewal of the public mandate the elected House holds.

The question is testing whether new citizens have remembered Discover Canada's exact figure. The guide commits to every four years as the traditional interval for House of Commons elections. The right test answer matches that.

The wrong answer choices each pick a different interval. Discover Canada never says elections happen every three, five or six years. Five years is the typical Governor General term. Senators serve until age 75 — no fixed term at all. Only the House of Commons has the four-year standard.
