Sir Wilfrid Laurier Day is celebrated on:

Discover Canada records this in one direct label. The guide writes: Sir Wilfrid Laurier Day November 20. The date the test wants is therefore November 20.

The day honours a specific Prime Minister. Discover Canada commits Sir Wilfrid Laurier Day to honouring Sir Wilfrid Laurier — described in the guide as "the first French-Canadian prime minister since Confederation" who "encouraged immigration to the West." So November 20 is one of two named Prime-Minister-honouring days in the Canadian holiday calendar — the other being Sir John A. Macdonald Day on January 11.

Laurier shaped western Canada. Discover Canada writes that under Laurier's leadership, "the railway made it possible for immigrants, including 170,000 Ukrainians, 115,000 Poles and tens of thousands from Germany, France, Norway and Sweden to settle in the West before 1914 and develop a thriving agricultural sector." So Laurier's pro-immigration policy directly built western-Canadian society as we know it today. Honouring him with a named day reflects this transformative contribution. His portrait is also on the $5 bill — meaning his face is in everyone's pocket alongside the national-day commemoration on November 20.

Sir Wilfrid Laurier Day fits the Canadian calendar. Discover Canada places November 20 between Remembrance Day (November 11) and Christmas Day (December 25). The full Canadian holiday calendar runs from New Year's Day (January 1), Sir John A. Macdonald Day (January 11), Good Friday and Easter Monday in spring, Vimy Day (April 9), Victoria Day (Monday preceding May 25 — the Sovereign's birthday), Fête nationale Quebec (June 24), Canada Day (July 1), Labour Day (first Monday of September), Thanksgiving Day (second Monday of October), Remembrance Day (November 11), Sir Wilfrid Laurier Day (November 20), Christmas Day (December 25), and Boxing Day (December 26). So November 20 honours the Prime Minister in late November, sitting between the Remembrance Day war commemoration and the Christmas-and-Boxing-Day window. When the test asks the date of Sir Wilfrid Laurier Day, the source-precise answer is November 20.

The question is testing whether new citizens know the date of Sir Wilfrid Laurier Day. Discover Canada commits to one date: November 20. The right test answer matches that.

The wrong answer choices each pick a different date. "January 11" is Sir John A. Macdonald Day — the OTHER named Prime-Minister-honouring day, not Laurier. "July 1" is Canada Day. "March 17" is not named in the source. Only November 20 — the date the source explicitly names — matches.
