Sir John A. Macdonald Day is celebrated on:

Discover Canada records this in two direct sentences. The guide writes: Sir John A. Macdonald Day January 11. The guide also writes: Parliament recognized January 11 as Sir John A. Macdonald Day. The date the test wants is therefore January 11.

The day was officially recognised. Discover Canada commits Sir John A. Macdonald Day to a specific recognition: Parliament recognized the day. So January 11 was officially designated by Parliament — making it more than just a customary observance, but a formal national-honour day.

The day honours Canada's first Prime Minister. Discover Canada writes: "In 1867, Sir John Alexander Macdonald, a Father of Confederation, became Canada's first Prime Minister." So January 11 honours the founding Prime Minister — the political leader who led Canada through Confederation in 1867 and the early consolidation of the country. Macdonald was "a former member of the voluntary government militia in Upper Canada" who became one of the Fathers of Confederation alongside Sir Étienne-Paschal Taché and Sir George-Étienne Cartier.

January 11 sits early in the Canadian holiday calendar. Discover Canada places January 11 second in its National Public Holidays list — between New Year's Day (January 1) and the spring Easter holidays (Good Friday and Easter Monday). The full Canadian calendar runs from New Year's Day, Sir John A. Macdonald Day, Good Friday, Easter Monday, Vimy Day (April 9), Victoria Day (Monday preceding May 25 — the Sovereign's birthday), Fête nationale Quebec (June 24, Feast of St. John the Baptist), 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 Sir John A. Macdonald Day on January 11 is the third holiday of the Canadian year — and the first one honouring a specific historical figure: Canada's founding Prime Minister. (Sir Wilfrid Laurier Day on November 20 is the other named PM-honouring day, much later in the year.) When the test asks the date of Sir John A. Macdonald Day, the source-precise answer is January 11.

The question is testing whether new citizens know the date of Sir John A. Macdonald Day. Discover Canada commits to one date: January 11. The right test answer matches that.

The wrong answer choices each pick a different date. "November 20" is Sir Wilfrid Laurier Day — honouring a different Prime Minister. "July 1" is Canada Day — the founding day, not Macdonald's day. "December 11" is not named in the source. Only January 11 — the date the source explicitly names — matches.
