Dave Jenniss, the son of a Métis father from the Malecite Nation, became the associate artistic director at Montreal's Ondinnok theatre in 2016. He is also a self-taught actor and playwright. His career has been infused with Indigenous culture since 2004. He performed on stage in Hamlet-le-Malécite, Wigwam, Wulustek, Contes urbains, Les papillons de Nuit, Boeing Boeing, L'Amour à l'agenda, Toc Toc, Confidence trop intime, Charlotte and Zone. In 2013 he won the Théâtre Denise-Pelletier students' choice award in the best supporting actor category for his performance in the role of Moineau in Zone.
On television, he has had roles in La grande bataille 2, C'est ici qu'on le dit, Les Rescapés de la justice and Shaputuan, and he also played a lovable raccoon in three seasons of the children's series Mouki.
Since 2008, his reputation as a writer has grown steadily thanks to various plays grounded in Indigenous culture, such as Wulustek, Le tambour du temps, Delphine rêve toujours and Mokatek et l'étoile perdu.
