[1] McMaster frequently practices self-portraiture and portraiture to explore themes of First Nations peoples and cultural identity, and incorporates elements of performance and installation to preserve her mixed heritage and sites of cultural history in the Canadian landscape.
[3][4] In her work, McMaster explores "tensions surrounding understanding one's personal identity and heritage, especially her own as a woman of Indigenous (Plains Cree) and European (British/Dutch) descent.
She makes use of such elaborate props in works such as Winged Callings (animal costumes) or Aphoristic Currents (collar "fashioned out of hundreds of twisted newspapers") in order to examine the tensions between cultural and personal memory as well as how they interact with imagination.
[12] Other distinctions she received include the Charles Pachter Prize for Emerging Artists,[13] and the Doris McCarthy Scholarship.
[2] A survey of her work was organized by the Carleton University Art Gallery (CUAG) and curated by Heather Anderson.
