For as long as she can remember, Isabelle Tremblay has been fascinated by space exploration. In fact, a children’s book about the Moon, the Sun and the stars compelled her to learn to read.
She has gone on to spend her career at the Canadian Space Agency, where she has contributed systems engineering expertise to two high-profile missions: the weather station on NASA’s Phoenix Mars Lander, and two instruments on the James Webb Space Telescope. Both were historic projects, and Tremblay’s work was key in ensuring the success of Canada’s contributions.
She led an unprecedented effort to raise the CSA’s project management capacity class by two levels in just three years (half the expected timeline), a landmark accomplishment among federal departments, allowing the agency to take on larger, higher-risk investments. “It was about mobilizing the organization around a clear vision, articulating its strategic importance, and empowering teams to contribute to a shared outcome,” she says.
Tremblay also helped create Health Beyond, an initiative that developed medical technologies enabling future astronauts on deep-space missions to manage their own health and medical care. These technologies can also improve healthcare outcomes for remote and underserved communities, including those in Canada’s North.
As Executive Director, Space Infrastructure, Tremblay leads the development and operations of Canada’s satellite systems that protect communities, steward natural resources, and ensure the long‑term sustainability of space. She sees the purpose of these activities as “Space for Earth.”
Giving back to her profession is a priority for Tremblay. She has served on the board of the Ordre des ingénieurs du Québec and on the programming committee of the Montréal Science Center, promoted engineering and STEM careers to young women, and worked to strengthen general science literacy. “I want to inspire the next generation. It's also important to foster a representative workforce. To solve increasingly complex problems, we must embrace diverse perspectives,” she says.
Her goal is to further advance Canada’s space program so that it thrives, delivering tangible benefits to Canadians and expanding opportunities for the next generation.
“Space exploration has this unique power to inspire because it elevates our confidence in the future and in our ability to work together. It expands our perspective on what’s possible. When we see ambitious goa
