In which year were most female citizens aged 21 and over granted the right to vote in federal elections?

Discover Canada records this in one direct sentence about federal women's suffrage. The guide writes: In 1918, most Canadian female citizens aged 21 and over were granted the right to vote in federal elections. The year the test wants is therefore 1918.

Two precise commitments. Discover Canada commits the federal vote for most Canadian women to TWO specific facts: (1) the year is 1918, and (2) the eligible group was most Canadian female citizens aged 21 and over. So the source is unambiguous on both the year and the qualifying age. The 1918 extension came as the First World War was ending and was a major step in Canadian democratic history.

The federal extension was a two-step process. Discover Canada commits the federal franchise to TWO years: 1917 and 1918. "In 1917, thanks to the leadership of women such as Dr. Stowe and other suffragettes, the federal government of Sir Robert Borden gave women the right to vote in federal elections — first to nurses at the battle front, then to women who were related to men in active wartime service." So the 1917 extension was limited to specific named groups: nurses at the battle front, then women related to men in active wartime service. The 1918 extension then broadened the right to most Canadian female citizens aged 21 and over — making it general rather than tied to wartime service.

The chronology of women's voting rights in Canada. Discover Canada commits the broader chronology to several specific milestones: 1916 (Manitoba — first province to grant women voting rights); 1917 (federal limited extension); 1918 (most Canadian female citizens aged 21 and over granted the federal vote); 1921 (Agnes Macphail, "a farmer and teacher, became the first woman MP"); 1940 (Quebec — last province to grant women the vote, thanks to "the work of Thérèse Casgrain and others"). So 1918 sits in the middle of this chain — making it the federal turning point in Canadian women's suffrage. The named founder of the suffrage movement in Canada was Dr. Emily Stowe, the first Canadian woman to practise medicine. So when the test asks the year most Canadian female citizens aged 21 and over were granted the federal vote, the source-precise answer is 1918.

The question is testing whether new citizens know the year of the federal-vote extension to most Canadian women. Discover Canada commits to one year: 1918. The right test answer matches that.

The wrong answer choices each pick a different year. The first choice is the year Manitoba (provincially) first granted women the vote — not the federal extension. The third choice is not named in the source for any women's-suffrage event. The fourth choice is also not named in the source for women's-suffrage. Only 1918 — the source's exact named year for the broad federal extension — matches.
