Her mother's family is from Papaschase First Nation, Alberta, and they also lived at Kikino Metis settlement for several years. L'Hirondelle's father emigrated from Germany as a young man shortly after WWII, and initially worked as an inventor for CIL and then later, in the oil industry moving the family around the western provinces to be near many of his gas plant startups. The family eventually moved to Calgary in 1964, where she attended St. Margaret's Elementary and Junior High School.^[4] Her last name (L'Hirondelle, her mother's maiden name) means swallow, a "migratory swift-flying songbird."^[5]

She spent a year at the Alberta College of Art from 1980-1981,^[6] and immediately afterwards attended a 2D course at the University of Calgary for one summer session.^{[citation needed]} She attended the Royal Conservatory of Music in Toronto, Ontario in 1990 and also studied voice, theory and composition privately for several years previous to that. She also studied to be a yoga teacher through Calgary Yoga Centre and Herbalism at Wild Rose College of Natural Healing in Calgary. ^{[citation needed]} In 2015 she graduated with an MDes in Inclusive Design, from OCAD University, receiving the OCAD University President's medal.^[7][8] In 2016 she became a PhD candidate with SMARTlab at University College Dublin (UCD) and where she was awarded an Irish Research Council Enterprise scholarship grant in collaboration with Irish world music group's record label Kíla Records.^[9]

L'Hirondelle's practice is multi- and inter-disciplinary, with a performative focus. Her work is described as blurring the boundaries between art and activism; memory and forgetting; mind and body; and artist and the broader community.^[21]

Early work such as the performance work dearth (by means of the senses), was a collaboration with Mark Dicey at the Walter Phillips Gallery at the Banff Centre in Alberta in 1992.

This led to her consultancy and eventual co-storyteller in residence role, along with other projects with the Meadow Lake Tribal Council.^[23][4] L'Hirondelle received another Toronto Arts Council grant in 2015, this time to return to the idea of composing using traditional song forms for Indigenous language retention.^[24]
