Casavant Frères Ltée.
Opus 2179, 1976

The original organ was built by Charles Summer Warren, of Montréal, in 1871 [Ed.: Elsewhere reported as 1873, cost $5000. Also S.R. Warren & Sons, spec. Charles, were not established until 1879, and Charles is not reported to be involved before that date. It is highly likely the company was operating still as S. R. Warren at this date.]

In 1918, the instrument was rebuilt and enlarged by Karn-Morris/Woodstock, of Woodstock, ON. It was again completely rebuilt, incorporating much of the original pipework, by Casavant Frères, of St Hyacinthe, QC, in 1952/1953. In 1976, they further modified and added to the instrument when the Choir division was moved to the west of the Great division and left unenclosed. A Trompette-en-Chamade was added in 1997 by Guilbault-Thérien, of St Hyacinthe. In 2012, the 1970s Contrabass was replaced by an Open Wood made by C.S. Haskell, of Philadelphia, in the 1920s.
