Passionate of theatre and cinema from a young age, Éléonore began developing her affection with theatre internships and camera acting workshops from Danièle Fichaud. She gets her first cinema role in 2018 with Dérive by David Uloth. She then discovers television, where she shines in roles such as Nina, a fragile and moving character in Cerebrum, or Astrid Voyer, an impulsive teenager in seasons 4,5 and 6 of L’Échappée. She also makes a striking appearance in Bête Noire, Sophie Deraspe’s series.

Through the cast of La Déesse des mouches à feu, feature-length movie by Anaïs Barbeau-Lavalette, Éléonore quickly makes a comeback to cinema. She plays Marie-Ève, a role that will win her a nomination at the Gala Québec Cinéma in 2021 in the « Best supporting actress » category. That same year, she was also part of Hygiène Sociale by Denis Côté. In addition, for her role in Guerres, by Nicolas Roy, she receives the female performance award at the Karlovy Vary festival. In 2022, we see her in Charlotte Le Bon’s Falcon Lake.
