Philippe Falardeau won the award twice, Bernard Émond once and Ken Scott didn't win any award. Louis Bélanger, Xavier Dolan and Denis Villeneuve also won the award twice. Xavier Dolan became the first screenwriter to receive two nominations in the same year for Mommy and Tom at the Farm (Tom à la ferme) in 2015, followed in 2023 by Éric K.
