What day is celebrated as Vimy Day?

Discover Canada records this in one direct sentence. The guide writes: April 9 is celebrated as Vimy Day. The day the test wants is therefore April 9.

The reason for the date is the underlying battle. Discover Canada writes: "The Canadian Corps captured Vimy Ridge in April 1917, with 10,000 killed or wounded, securing the Canadians' reputation for valour as the 'shock troops of the British Empire.'" The capture began on April 9, 1917 — the day Vimy Day commemorates.

The battle's significance is captured in a quoted line. The guide says: "It was Canada from the Atlantic to the Pacific on parade... In those few minutes I witnessed the birth of a nation." Vimy Day therefore is not just a war memorial; Discover Canada presents it as the anniversary of a moment of Canadian national emergence — and adds that the "Vimy Memorial in France honours those who served and died."

The Vimy story sits inside the wider story of Canada's First World War service that Discover Canada describes. The guide notes that the war began in 1914 and ended in 1918. "More than 600,000 Canadians served in the war, most of them volunteers, out of a total population of eight million," and "in total 60,000 Canadians were killed and 170,000 wounded." The war ended in "the Armistice on November 11, 1918," the date that became Remembrance Day. So Vimy Day on April 9 and Remembrance Day on November 11 are the two main First World War commemorations the guide identifies.

The question is testing whether new citizens have remembered Discover Canada's exact day. The guide commits to April 9 — and pairs the day with the battle (Vimy Ridge), the year (1917) and the casualty figure (10,000 killed or wounded).

The wrong answer choices each test the reader. The guide does not connect Vimy Day with April 1, April 15 or April 25; only April 9 is named as the day of commemoration.
