Former NASA chief economist takes the helm of Canada’s space agency, bringing more than two decades of experience in space policy, economics and exploration.
Canada’s space sector is entering a new chapter of leadership as the federal government appoints Alexander MacDonald as the new president of the Canadian Space Agency (CSA), bringing internationally recognized expertise in space economics, exploration and strategic policy to the organization.
Announced on November 4, 2026, by the Honourable Mélanie Joly, Minister of Industry and Minister responsible for Canada Economic Development for Quebec Regions, the appointment positions MacDonald to lead the agency as Canada advances innovation, scientific discovery and sovereign space capabilities.
MacDonald succeeds Lisa Campbell, who has served as president of the CSA since 2020.
From NASA to Canada’s Space Agency
With more than two decades of experience in the global space sector, MacDonald brings an extensive background in shaping major space exploration initiatives and economic strategies.
Most recently, he served as NASA’s first chief economist, where he helped establish the agency’s Moon to Mars strategy and Artemis program, two major initiatives supporting the future of human space exploration.
His career at NASA also included several senior leadership positions, notably senior economic advisor in the Office of the Administrator and founding program executive of the Emerging Space Office.
Beyond his professional achievements, MacDonald holds degrees from Queen’s University, the University of British Columbia and the University of Oxford. An award-winning author, he was also recognized with the NASA Exceptional Service Medal in 2024.
Strengthening Canada’s Space Leadership
The appointment follows an open, competency-based selection process and reflects the federal government’s emphasis on the growing importance of space to Canada’s national security, economic competitiveness and technological development.
Welcoming MacDonald to his new role, Minister Joly highlighted the experience and strategic perspective he brings to the agency.
“I am pleased to welcome Alexander MacDonald as president of the Canadian Space Agency. He brings to the position extensive leadership experience, deep expertise in space policy and economics, and a strong understanding that space is crucial to our national and economic security. With this background, he is perfectly suited to lead the agency in advancing innovation, scientific discovery and economic growth through space exploration and sovereign capability development. I would also like to thank Lisa Campbell for her outstanding leadership of the agency over the past six years, as well as Senior Vice President Jean-Claude Piedboeuf for serving as acting president over the past several months and supporting a smooth leadership transition.”
The transition also recognizes the contributions of Campbell, who led the agency for six years, and Jean-Claude Piedboeuf, who served as acting president during the preceding months.
With MacDonald now at the helm, the Canadian Space Agency gains a leader whose experience spans the intersection of space exploration, economic strategy and public policy—areas central to Canada’s ambitions in an increasingly competitive global space sector.
