Canada has a rich heritage of organ building, with instruments dating back to the early 19th century. Over time, such instruments may suffer from decay, neglect or modernization, so they are no longer in their original condition, and we can no longer hear their original sound.
In a bid to acknowledge and publicise historic instruments across the country, and prevent their loss, the RCCO instituted its Historic Organs program. An instrument may qualify in one of three classes, depending on its history and condition.
Qualifying instruments will receive an official citation certificate, which may be affixed to the organ case. The current list of designated Historic Organs can be seen here.
