"God Save the Queen" has been sung in Canada since the late 1700s and by the mid 20th century was, along with "O Canada", one of the country's two "de facto" national anthems, the first and last verses of the standard British version being used.By-laws and practices governing the use of either song during public events in municipalities varied; in Toronto, "God Save the Queen" was employed, while in Montreal it was "O Canada".
