    Founded in 1946 as Orgue Providence in the village of La Providence, Québec . The partnership between Maurice Guilbault and Antonio Delage started as an organ supply firm and gradually expanded into building organs. Andre Guilbault, son of Maurice, joined the firm in 1955. After Maurice retired, Andre became head of the firm. Guy Therien, a voicer at Casavant, joined the firm in 1968, and later became a partner. In 1969, the firm began building mechanical action instruments, although it also continued to construct and service electropnuematic organs.

    The firm name was changed to Guilbault-Therien in 1978. The firm relocated to St. Hyacinthe, Québec in 1985. Andre retired in 1992, Alain Guilbault (no relation) became a partner and continued the firm with Guy Therien until Therien's death in 2001. Alain Guilbault then reconstituted the firm with new partners as Guilbault Bellvance Carignan.
