The House of Commons has 308 electoral districts.

Discover Canada records this in one direct sentence about federal elections. The guide writes: Canada is divided into 308 electoral districts, also known as ridings or constituencies. An electoral district is a geographical area represented by a member of Parliament (MP). The citizens in each electoral district elect one MP who sits in the House of Commons to represent them, as well as all Canadians. The number the test wants is therefore 308 — true.

Three precise commitments. Discover Canada commits the structure of federal representation to THREE specific facts: (1) Canada is divided into 308 electoral districts; (2) these districts are also known as ridings or constituencies — three names for the same geographic unit; (3) each district is represented by a member of Parliament (MP). So the source pairs the number 308 to the named geographical units that fill the House of Commons.

One MP per district, by election. Discover Canada commits the selection of MPs to a precise rule: "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 each district elects exactly one MP — meaning 308 districts produce 308 MPs in the House of Commons. The MP represents both the local district AND all Canadians at the same time. The election method is direct: "The candidate who receives the most votes becomes the MP for that electoral district."

The wider electoral framework. Discover Canada commits the federal-election framework to a specific operating set: "Canadian citizens who are 18 years old or older may run in a federal election. The people who run for office are called candidates. There can be many candidates in an electoral district." So 308 elections — one in each district — happen at the same time across the country, producing the 308 members of the House of Commons. The voters' lists used for these elections are produced from the National Register of Electors by Elections Canada, the neutral agency of Parliament responsible for federal elections. So the 308-district structure is the building block of Canada's elected representation in the federal Parliament. The House of Commons is described elsewhere in the guide as "the representative chamber, made up of members of Parliament elected by the people, traditionally every four years." So when the test asks whether the House of Commons has 308 electoral districts, the source-precise answer is true.

The question is testing whether new citizens know the number of federal electoral districts. Discover Canada commits to one number: 308. So the statement that the House of Commons has 308 electoral districts is true.

The wrong answer ("False") reverses the source — Canada is divided into 308 electoral districts. Each district elects one MP, who sits in the 308-seat House of Commons. Only the true answer matches the source.
