Stantec Spearheads Arctic Radar Development

On March 4, 2026, Stantec Inc. was officially selected to lead the initial design and project management phases of Canada's Arctic Over-the-Horizon Radar (A-OTHR) project. This critical infrastructure initiative, backed by the Department of National Defence, aims to establish a sophisticated early-warning system across Canada's vast northern regions. Collaborating within an integrated project delivery model, Stantec will provide extensive multidisciplinary project management and design expertise. Construction services for this large-scale defense project will be managed by a joint venture between Aecon and Pomerleau, who will work closely with Stantec to implement the vision. The A-OTHR system is designed to significantly enhance Canada's ability to detect and monitor aerospace and maritime threats along Arctic routes, marking a substantial federal investment in national security. This selection highlights Stantec's long-standing partnership with the Department of National Defence and its commitment to strengthening vital national infrastructure.

This endeavor highlights the critical importance of robust defense infrastructure in safeguarding national interests and sovereignty, particularly in strategically vital regions like the Arctic. Stantec's involvement in this project demonstrates the company's technical leadership and its role in contributing to Canada's national security framework. Furthermore, it reflects a broader trend of significant investments in advanced surveillance technologies to counter evolving geopolitical challenges and protect national borders.
