Born in Moose Factory, Ontario, Jules was raised in Moosonee by her Cree-speaking grandparents and in Ottawa, with her mother — a warrior of the Canadian Residential school system. Jules is a band member of Attawapiskat First Nation, the ancestral lands of the MoshKeKo InNiNeWak.
She currently resides in Vancouver, where she is a PhD candidate with the Institute of Gender, Race, Sexuality, and Social Justice at the University of British Columbia. Her research focus is Indigenous documentary. In 2010, Jules completed her masters at Ryerson University in Documentary Media; she was awarded the Award of Distinction for her thesis work, as well as the Graduate Ryerson Gold Medal for highest academic achievement. While in graduate school, she produced her first feature documentary film Remembering Inninimowin, regarding her journey of remembering Cree. After graduation, Jules was one of six women selected for the Women in the Directors Chair program at the Banff Center, where she directed a scene from her feature script Broken Angel, which is currently in development. Jules’ television series AskiBOYZ (2016), co-produced with Big Soul Production, is now being aired on Aboriginal Peoples Television Network.
Jules’ company VisJuelles Productions Inc. has a number of films and other media works in development. In 2017, she released her short documentary NiiSoTeWak. Her second CBC short OshKiKiShiKaw: A New Day was released in early 2019.
In 2017, she released Butterfly Monument, a short documentary about her relation, the late Shannen Koostachin, with co-director/producer Rick Miller.
Jules was the 2017 Aboriginal Storyteller-in-Residence with the Vancouver Public Library, where she further developed her poetry.
In the fall of 2018, Jules' latest narrative film OChiSkwaCho premiered at ImagineNative Film Festival. She is also in development with two television series: Threshold with Jules Koostachin and SACRED.
In 2018, her first book of poetry, Unearthing Secrets, Gathering Truths, was published with Kegedonce Press and she was also a selected filmmaker for the TIFF Filmmakers Lab. Jules is currently writing her first novel, Moccasin Souls, and is aiming to defend her PhD thesis in the fall of 2019. She carries extensive knowledge working in Indigenous community in several different capacities and these community experiences continue to feed her advocacy and her arts practice.
