[1][2] The Choir is composed of accomplished amateur singers from Hamilton and the neighbouring cities of Burlington, Oakville, Mississauga and Simcoe.
Notable performances by the ensemble include the North American première of Verdi's Requiem[citation needed] and the Canadian premieres of Górecki's Miserere[3][4] and Mahler's Symphony No.
The choir has performed at Roy Thomson Hall in Toronto, The Sanderson Centre in Brantford (with the Buffalo Philharmonic Orchestra), and at the Brott Music Festival in Hamilton.
In 1969 Wilson founded a 36-voice subsidiary choir, the Bach Elgar Chamber Singers; they performed small concerts in Hamilton and southern Ontario for a number of years.
During the 1970s and 1980s the choir continued its concert series at Christ's Church Cathedral, with Donald Kendrick conducting from 1974 to 1978 and from 1981 to 1983, Philip David Morehead from 1978 to 1980, and Denise Narcisse-Mair from 1980 to 1981.
