The Grand Philharmonic Choir (GPC) organization is one of this country’s leading choral institutions. The GPC consists of four choirs: a 110-voice main choir; a 35-voice chamber choir; a youth choir; and a children's choir. Led by artistic director Mark Vuorinen, the GPC presents 20+ concerts a year, many in Kitchener’s acoustically superb Centre In The Square and in local church buildings. Repertoire is a rich blend of traditional masterworks as well as new works by Canadian and international composers. Auditions are held throughout the year.
