"O Canada" (French: Ô Canada) is the national anthem of Canada. The song was originally commissioned by Lieutenant Governor of Quebec Théodore Robitaille for the 1880 Saint-Jean-Baptiste Day ceremony; Calixa Lavallée composed the music, after which, words were written by the poet and judge Sir Adolphe-Basile Routhier. The lyrics were originally in French; an English version was created in 1906. Robert Stanley Weirwrote in 1908 another English version, which is the official and most popular version, one that is not a literal translation of the French. Weir's lyrics have been revised twice, taking their present form in 1980, but the French lyrics remain unaltered. "O Canada" had served as a de facto national anthem since 1939, officially becoming Canada's national anthem in 1980 when the Act of Parliament making it so received royal assent and became effective on July 1 as part of that year's Dominion Day (now known as Canada Day) celebrations.
