After participating in a first commercial ad at the age of 6, Thivierge's career started very early at the age of eight when he had his first minor television and film roles on Épopée rock, Manon, The Years of Dreams and Revolt (Les Années de rêves), The Alley Cat (Le Matou) and The Dame in Colour (La Dame en couleurs) in 1984 and 1985.

However, it was in the mid-2000s where Thivierge started to play lead roles in Nitro as well as in the 3 L'il pigs, two of the biggest box-office Quebec hits in 2007.

Another notable role was in Lance et Compte: Le Revanche in 2006, where he played a paraplegic lawyer defending one of the fictional National de Quebec hockey who was charged with second degree murder and later for involuntary homicide following an on-ice incident where a player died from his injuries following a check from the accused player.

During his lengthy acting career, Thivierge participated in a total of 30 films and television series including Le Négociateur, Casino, Les Immortels, Chambres en Ville and Ramdam.
