Sir Andrew Davis, conductor laureate of the TSO, was the orchestra's interim artistic director from 2018 to 2020.

The first conductor was Luigi von Kunits, and that season there were twenty concerts, as well as a performance at a spring festival.

[2] In 1951, the orchestra made headlines 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.

[5] 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.

[16] In April 2015, controversy ensued after the TSO cancelled the appearance of Valentina Lisitsa, citing Twitter postings by her in relation to the war in Donbas which were seen as conducive to "public incitement of hatred" under the Criminal Code of Canada.

[20] In April 2018, the TSO announced the appointment of Matthew Loden as its chief executive officer (CEO), effective July 2018.

On the basis of this appearance, the TSO announced the appointment of Gimeno as its next music director, effective in the 2020-2021 season, with an initial contract of 5 years.

[24] In January 2022, the TSO announced the appointment of Mark Williams as its next chief executive officer, effective April 2022.
