St. Thomas’ Church has two organs built by Casavant Frères of Québec, Canada. The primary organ is a 3-manual, 55-rank instrument built in 1964, with renovations and additions in 2003. It supports hymn-singing brilliantly and can be used to perform the standard organ repertoire. The second is a 4-rank mechanical action positive organ built by Casavant in 1978.
