"O 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 original lyrics were in French; an English translation was published in 1906.[1] Multiple English versions ensued, with Robert Stanley Weir's version in 1908 gaining the most popularity, eventually serving as the basis for the official lyrics enacted by Parliament.
