Working on construction sites, Thiffault composed new versions of Quebecois folk songs,[1] and also wrote many songs setting new lyrics to traditional melodies.
[5][6] Thiffault wrote songs honouring local sports figures, including hockey players Maurice Richard, ("Le Rocket Richard"),[7] and Guy Lafleur ("La Tourne à Ti-Guy Lafleur").
[8] Other songs that he wrote were "Je parle à la française"[9] and "En écoutant Y mouillera pu pantoute".
[10] In 1988, a documentary film about Thiffault's life, created by Serge Giguère, was released.
[11][12] His songs continue to be played and recorded in Quebec; the band Carotté included "“Tape la bizoune" on their debut album.
