When did o canada become canada's national anthem?
"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. 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. Weir's lyrics have been revised three times, most recently when "An Act to amend the National Anthem Act (gender)" was enacted in 2018. The French lyrics remain unaltered. "O Canada" had served as a "de facto" national anthem since 1939, officially becoming the country's national anthem in 1980 when Canada's "National Anthem Act" received royal assent and became effective on July 1 as part of that year's Dominion Day (today's Canada Day) celebrations.

O Canada
In 1970, the Queen in Right of Canada purchased the right to the lyrics and music of "O Canada" from Gordon V. Thompson Music for $1. The song finally became the official national anthem in 1980 with the passage of the "National Anthem Act." The Act replaced two of the repetitions of the phrase "We stand on guard" in the English lyrics, as had been proposed by the Senate Special Joint Committee. This change was controversial with traditionalists and, for several years afterwards, it was not uncommon to hear people still singing the old lyrics at public events. In contrast, the French lyrics are unchanged from the original version.
