Why do Canadians celebrate Victoria Day?

Discover Canada records this in its public-holidays table. The guide writes: Victoria Day — Monday preceding May 25 (Sovereign's birthday). The reason the test wants is therefore to mark the Sovereign's birthday.

Victoria Day is the Sovereign's official Canadian birthday. Discover Canada attaches the parenthetical phrase "(Sovereign's birthday)" directly after Victoria Day in its holidays table, making the holiday's purpose explicit. The Monday-preceding-May-25 date is the official Canadian observation of the reigning monarch's birthday — separate from the actual royal date of birth.

The day is named after Queen Victoria. Discover Canada mentions Queen Victoria multiple times in connection with major Canadian milestones: "Confederation in 1867 during Queen Victoria's reign," Ottawa "chosen as the capital in 1857 by Queen Victoria," and Alberta "named after Princess Louise Caroline Alberta, fourth daughter of Queen Victoria." So Victoria — the Sovereign during whose reign Canada was born as a self-governing Dominion — has a personal namesake holiday in Canada.

The Sovereign remains a constitutional figure today. Discover Canada writes that "the Crown has been a symbol of the state in Canada for 400 years" and that Canada has been a constitutional monarchy "in its own right since Confederation in 1867." Today's Sovereign — Queen Elizabeth II in the guide — has been Queen of Canada since 1952. Victoria Day, then, is not just a memory of one 19th-century monarch — it is the annual Canadian celebration of the Sovereign's role in Canadian constitutional life, regardless of who currently holds that role.

The question is testing whether new citizens know the reason for Victoria Day. Discover Canada commits to one purpose: to mark the Sovereign's birthday. The right test answer matches that.

The wrong answer choices each pick a different reason. Canada Day (July 1) honours the country's birth, not Victoria Day. The start of summer is a popular cultural association but not the official reason in the guide. Queen Victoria's death is not the holiday's purpose — Canadians celebrate the Sovereign's birthday, not a death anniversary. Only the Sovereign's-birthday reason matches the source.
