The Organ

The organ of the Church of St. Andrew and St. Paul was built in 1931 by the renowned Casavant Frères of Ste. Hyacinthe, as that firm's opus #1457. It is one of the largest instruments on the island of Montreal, containing nearly 7,000 pipes. About 70% of the pipes are located in the chancel; the other pipes speak from the rear gallery. Only the Trompette en chamade (installed in 1992) is visible, mounted prominently below the Black Watch window.

The instrument was cleaned and overhauled by Casavant in 1976-77, and several stops and a new console were added by Caron, Gagnon, Baumgarten in 1992. The tonal work of these rebuilds lent the instrument a neo-baroque flavour, but was unfortunately of uneven technical and musical quality. The console was rebuilt by Casavant in 2001. A gradual tonal renovation of the organ has been ongoing since 2010, whose goal is to replace the 1970s and 1990s-era neo-classical stops with pipework of the early 20th century, of superior material and tonal quality. Like all of the Casavant instruments built between ca. 1890 and 1960, op. 1457 was conceived in the late-Romantic Anglo-American style, and remains a monumental essay in the genre.

The tonal design of the instrument was conceived for the playing of orchestral transcriptions and orchestrally-inspired solo repertoire and accompaniments; the Wagnerian orchestra, with its kaleidoscopic yet seamless colour changes, was the aesthetic ideal for many organists of the period.

Léa Moisan-Perrier

Ms. Léa Moisan-Perrier has been the artistic director of the Choeur des Enfants de Montréal (CEM) since 2017, and is the artistic director of Les Voix Parallèles, a choir made up of graduates of l’École de Musique Vincent d’Indy that she founded in 2015.

We are glad to welcome her to our church family.

Interim Director of Music

William Duffy

Sought after for his “command of the seemingly impossible high tessitura” (South Florida Classical Review), California-born countertenor William Duffy is an active early music soloist and ensemble singer in North America. While his first contact with music was through the strings of his 1/16 Suzuki violin, today William prefers the medium of vibrating air with his body as the instrument. He continues to explore the extremes of his musical voice through the music of the renaissance, baroque, and today. William appears frequently as a soloist and ensemble singer in Canada and the US, most notably with Seraphic Fire, Les Idées heureuses, Ensemble Caprice, and Ensemble vocal arts-Québec. William holds degrees in vocal performance (California State University, Chico) and choral conducting (McGill University). As a conductor, educator, and ensemble manager, William has worked with choirs of all types, including the Choir of the Church of St. Andrew and St. Paul, San Francisco-based Chanticleer Skills/LAB Choir, the award-winning Cantabella Children’s Chorus, Ottawa Choral Society, The National Youth Choir of Canada, and the McGill Schulich Singers. William is delighted to be in his eighth season with the Choir of the Church of St. Andrew and St. Paul.

Thomas Annand

Thomas Annand is widely regarded as one of Canada’s finest organists. After receiving First Prize in the RCCO National Organ Competition he became a student of the great French organist Marie-Claire Alain.

He has been a frequent soloist with the National Arts Centre Orchestra and Les Violons du Roy and has performed at such venues as the Carmel Bach Festival, Boston Early Music Festival, International Congress of Organists, Montreal Bach Festival and Ottawa International Chamber Music Festival. In 2021 he completed 29 years as Director of Music at St Andrew’s Church, Ottawa; under his direction the Choir grew to become a polished ensemble which not only performed the classic sacred repertoire every Sunday but also in annual concerts which regularly included the cantatas of J.S. Bach; during those years he also presented 200 weekly organ recitals covering 500 years of repertoire, notably the complete symphonies of Widor and integral cycles of the works of Liszt, Mendelssohn and Franck. He is also a noted harpsichordist (performing all the major keyboard works of Bach in seven marathon recitals in 2004/05), conductor (guest conductor of Thirteen Strings and founding conductor of Capital BrassWorks with whom he recorded a CBC SM5000 disc) and composer of choral and organ music.
