At what age are Canadian citizens added to the National Register of Electors?

Discover Canada records this in one direct sentence. The guide writes: The voters' lists used during federal elections and referendums are produced from the National Register of Electors by a neutral agency of Parliament called Elections Canada. This is a permanent database of Canadian citizens 18 years of age or older who are qualified to vote in federal elections and referendums. The age the test wants is therefore 18 years.

The age threshold is consistent across federal voting. Discover Canada commits to 18 as the qualifying age — meaning 18 is when Canadian citizens become eligible voters and can be added to the Register. The same age applies to all federal elections and referendums.

The age fits a wider Canadian rule. Discover Canada writes elsewhere that "every citizen over the age of 18 may vote" — meaning the 18-and-over threshold is the universal Canadian voting age, not just a Register-specific rule. Once a Canadian citizen reaches 18, they are eligible to vote in federal, provincial or territorial, and local elections.

The Register is a permanent database. Discover Canada describes it as "a permanent database of Canadian citizens 18 years of age or older." So once a citizen turns 18, they can be added to the Register and remain on it as long as they stay eligible. The Register triggers a voter information card mailed to each elector at election time, indicating "when and where you vote" and providing access to interpreters or special services. Citizens not on the Register can still register on election day — the threshold to vote is reaching the age of 18 and being a Canadian citizen.

The question is testing whether new citizens know the qualifying age for the National Register of Electors. Discover Canada commits to one age: 18 years. The right test answer matches that.

The wrong answer choices each pick a different age. 16 and 17 are below the federal voting age. 19 is above the threshold (the federal voting age is 18, not 19). Only 18 — the age at which a citizen becomes eligible to vote in federal elections and referendums — matches.
