Laboucan-Massimo joined
Greenpeace as a full-time campaigner in 2009. The following year, she became one of the founding organizers of the
Tar Sands Healing Walk, a prayer walk and demonstration against the impacts of Alberta oil and gas extraction that took place annually from 2010 to 2014. When Greenpeace formally launched its schooner
Rainbow Warrior III in 2011, Laboucan-Massimo performed a blessing on the ship with a Cree prayer and ceremony. On April 29, 2011, a ruptured pipeline
spilled approximately 4.5 million litres of oil near Little Buffalo. The leak was Alberta's largest in forty years. In the aftermath of the oil spill, Laboucan-Massimo's focus shifted to directly supporting a
renewable energy transition. In July 2013, Laboucan-Massimo's younger sister Bella Laboucan-McLean, an aspiring fashion designer living in Toronto, died from a fall off a condo balcony after a night out with five other people. Although Bella's death was considered suspicious by police, the investigation became stalled for lack of new information or evidence. Subsequently, Laboucan-Massimo joined calls for a
national inquiry into missing and murdered Indigenous women in Canada, advocating for a more effective inquiry process created by and for the family members of those affected. A national inquiry was finally launched in late 2015. Laboucan-Massimo completed a master's degree in Indigenous Governance from the
University of Victoria with a focus on renewable energy, and in 2015, as part of her degree project, she helped with the construction of a 20.8-kilowatt solar panel installation to power the local health centre in Little Buffalo. 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. == Media ==
