“O Canada” is Canada’s national anthem. Originally called “Chant national,” it was written in Québec City by Sir Adolphe-Basile Routhier (words in French) and composer Calixa Lavallée (music), and first performed there on 24 June 1880. It began to be sung widely in French Canada at that time and later spread across Canada in various English-language versions, of which the best-known was written by Robert Stanley Weir in 1908. The lyrics of this version were amended several times over the years, with the most recent changes occurring in February 2018; the French lyrics have been shortened but otherwise remain unaltered from the original. “O Canada” was approved as Canada’s national anthem by a Special Joint Committee of the Senate and House of Commons on 15 March 1967. It was officially adopted as Canada’s national anthem under the National Anthem Act on 27 June 1980. The Act was proclaimed by Governor General Edward Schreyer in a public ceremony on Parliament Hill on 1 July 1980.
