The TSO was founded in 1922 as the New Symphony Orchestra, and gave its first concert at Massey Hall in April 1923 with 58 musicians. The first conductor was Luigi von Kunits, and that season there were twenty concerts, as well as a performance at a spring festival.

In the summer of 1924, the symphony performed at the Canadian National Exhibition. The orchestra changed its name to the Toronto Symphony Orchestra in 1927. In 1929, the TSO made its radio debut with a one-hour broadcast on CBC Radio from the Arcadian Court of Simpson's department store.

After von Kunits' death in 1931, conductor and composer Ernest MacMillan served as music director for 25 years.

The orchestra had made headlines for its hiring practices in 1951, when it declined to renew the contracts of musicians, thereafter known as the Symphony Six who had been denied entry to the United States on suspicion of communist activities, during the McCarthy Era.

Andrew Davis was the TSO's music director from 1975 to 1988, and then was given the title of conductor laureate with the TSO.

The orchestra had financial and audience size problems in the 1990s, and in 1992 TSO musicians had accepted a 16% pay cut because of a threat of bankruptcy to the orchestra, with a promise from management to make up the loss in subsequent contract negotiations. By 1999, this pay restoration had not happened, which led to an 11-week musicians' strike that autumn. Relations between the musicians and management deteriorated, and the music director at the time, Jukka-Pekka Saraste, offered to serve as mediator in the situation.

By 2001, the orchestra had debt of $7 million, and both executive director Ed Smith and music director Saraste had left the ensemble.

Peter Oundjian was appointed as music director in January 2003 and became music director with the 2004–2005 season. The 2005 documentary film Five Days in September: The Rebirth of an Orchestra (Canada, 2005) recorded the first days of the TSO's inaugural season with Oundjian as its new music director.

By the 2006–2007 season, the subscriber base had increased to about 25,000, and the audience average capacity also increased to 84%. In November 2008, the orchestra reported its third consecutive year of budget surpluses, with average audience attendance of 88% (excluding concerts for schoolchildren), although the orchestra still retains overall debt of $8.9 million (Canadian).
