ONTARIO PHILHARMONIC A STORY OF SUCCESS
Ontario Philharmonic (OP) is a distinguished player in the classical music landscape of the province of Ontario, representing one of the leading performing arts organizations of Durham Region and GTA. OP is comprised of players among the finest professional musicians in the GTA and is led by one of Canada’s most distinguished conductors on the international scene, Marco Parisotto. OP was founded in the City of Oshawa, County of Ontario, in 1957 and during its history has evolved into one of the most exciting and respected orchestras in Ontario and Canada.
OP performs mainly at Ontario Tech University’s Regent Theatre in Durham Region, as well as various important GTA venues. Although the great symphonic and choral/symphonic repertoire is its mainstay, OP's programs reflect a wide variety of styles from Baroque/Classical/Romantic/Modern to light classical, pop music, jazz and world music, to satisfy the taste of all audiences, diverse cultures and youth.
OP also serves the community with vital and much-loved outreach programs: Orchestral Literacy Series, Children’s Classical Democracy Series and Seniors Living To The Beat.
In its first two decades, OP was comprised of local musicians performing symphonic and chamber music. OP’s first conductor was Francis J. Francis (1957-63), followed by Edward Oscapella Sr. (1963-7), Jacob Groob (1967-72), Roy Cox (1972-9) and Winston Webber, who conducted until 1994.An era of spectacular development began in 1996 when present Maestro Marco Parisotto was appointed Music Director. One of Canada's most distinguished conductors on the world stage, under his leadership the orchestra grew into a fully professional symphonic ensemble of outstanding artistic quality. With a strong vision and determination, Maestro Parisotto brought about significant and fundamental changes to every aspect of OP. With the introduction of innovative and original programming and the invitation of prominent Canadian and international soloists, success was assured as he steered OP to a high point of popularity with an ever-widening audience.
2008 marked the beginning of OP's association with one of Canada's newest and most successful universities: Ontario Tech University (formerly UOIT). This stellar alliance of Knowledge and Art ensures OP’s continued significant growth, organizationally and artistically. Ontario Tech generously provides its historic Regent Theatre for OP’s main concert series.
The year 2011 commenced OP’s highly successful concert series at Koerner Hall, Toronto and Durham’s Regent Theatre, showcasing some of the world's most renowned soloists. In its earlier years, OP was known as the Oshawa Symphony. Name changes in 1995 and 2008 answered the widening of its Ontario audience and its increasing role in providing audiences with world class symphonic music.
Since 2008 the orchestra has been known permanently as Ontario Philharmonic – a prestigious name fittingly reflecting its impressive development, its ON Tech partnership, its service to Ontario’s most densely populated area, and in homage to the beauty and grandeur of our province.
