The organization has six choirs composed of children between the ages of 5 and 18, under the artistic direction of Sarah Morrison.

The OCC was created in May 1994 by Glenda Crawford assuming the position as founder and director. The organization began with 40 children with its first rehearsal on September 12, 1994.
