Balmoral Hall was founded in 1901 as Havergal College, located at 122 Carlton Street. The name was changed in 1917 to Rupert's Land College. Sir James Aikins gave his home, known as Aikins House, to the United Church of Canada upon his death in 1929. In his will, he requested it be used as a girls' school and bestowed further funding to be used to that end. The school was named Riverbend School and opened in September 1929 at Balmoral Hall's present site. In 1950, due to declining enrollment at both schools, Rupert's Land College amalgamated with the Riverbend School at its site on Westminster Avenue. The school was christened Balmoral Hall School, after Balmoral Castle, and classes began in September 1950.
