The Hamilton Philharmonic Orchestra is an orchestra in Hamilton, Ontario. It was founded in 1949.
Starting in 1969, under the leadership of Boris Brott, the Hamilton Philharmonic Orchestra changed from an amateur ensemble to a professional orchestra. Brott raised the profile of the orchestra with innovative performances, including one held in the Dofasco steel mills. Attendance at concerts rose from 23,000 to 225,000.
A former concertmaster, the late Olive Short, mother of Tony and Emmy Award winning comic actor Martin Short, was the first female concertmaster in North America. She died in 1970 five years after being diagnosed with cancer.
