There are two pipe organs at the Cathedral: a three-manual and pedal instrument by Casavant Freres, and a single-manual continuo organ built by Bennett and Giuttari, and gifted by the Challice family in 2019, in memory of all of the musicians who have served at the Cathedral.

The Casavant Organ

The organ of the Cathedral is one of Calgary's most historic instruments. It was built by the renowned firm Casavant Freres and installed in 1906. It was significantly enlarged and overhauled in 1937 and again in 1955.

In 2002, the Calgary Universal Foundation for the Organ generously provided funds for the complete restoration of the instrument, including the replacement of the electro-pneumatic combination system with a solid state switching system and solid state logic combination system of 128 levels of memory. The present instrument consists of 39 stops over three manuals and pedal.
