Casavant Frères Ltée.
Opus 34, 1892

Joseph Casavant-s sons completely rebuilt the organ in 1892 as a 52-stop instrument over 3 manuals and pedal. The instrument used an electro-pneumatic action which represented a new summit for the Casavant firm. The main section of the organ is located in the rear gallery while a second organ, a 17-stop choir organ over 3 manuals and pedal, is located in two arches over the sanctuary and is known as the Sanctuary Organ. Both organs are played from the console in the rear gallery.

From the very beginning, the organ case was divided into two sections in order to show the magnificent stained-glass window. Originally the console was attached to the left organ case.

New stops were added in 1917. A more modern console was installed in 1940 when a major rebuild was undertaken and, in 1975, a revision of the electric action was carried out. (Cathedral website)
