In 2015 Laboucan-Massimo founded Sacred Earth Solar, an initiative supporting Indigenous-led solar energy projects across Canada, and also co-founded the organization Indigenous Climate Action, which advocates for Indigenous-led climate change solutions. She has supported Secwépemc activists in their protests against the Trans Mountain pipeline expansion, providing solar panels to power their tiny houses built along the proposed pipeline expansion route for the purpose of asserting Secwépemc traditional law and land rights. In 2017 Laboucan-Massimo was one of the inaugural recipients of the David Suzuki Fellowship, which aims to support "solutions-oriented" scientific research and inspire community action. She used the C$50,000 grant and professional mentorship to expand on her master's degree research in renewable energy. Laboucan-Massimo became Indigenous Climate Action's just transition director in 2019. As of 2021, she was serving as a board member for Seeding Sovereignty and NDN Collective and as a member of the executive steering committee of the Indigenous Clean Energy Social Enterprise.
