Stantec selected to deliver multidisciplinary engineering and design services for Canada’s Arctic Over-the-Horizon Radar project

Press Release

Stantec, a global leader in sustainable design and engineering, will deliver the first phase of the Government of Canada’s Arctic Over-the-Horizon Radar (A-OTHR) project, providing long-range, early-warning radar coverage of the country’s northern regions.

Defence Construction Canada selected Stantec and its consortium partners to execute the project under a collaborative integrated project delivery model, where Aecon and Pomerleau will provide construction services as a joint venture, and Stantec will undertake multidisciplinary project management and design services.

Supporting NORAD and North America defense

The A-OTHR system is part of a federal investment implemented by Canada’s Department of National Defence (DND) to modernize North American Aerospace Defense Command (NORAD) infrastructure—a network of sensors, command centers, and operational units that detect, validate, and warn of aerospace and maritime threats. The program will establish a long-range surveillance radar network to monitor Arctic routes to major North American population centres, renewing Canada’s North Warning System.

“We are honored to help advance NORAD’s modernization, drawing on our deep experience in delivering resilient, climate‑ready solutions across Canada,” said Gord Johnston, president and chief executive officer of Stantec. “Our long-standing partnership with Canada’s Department of National Defence reflects the trust built through decades of collaboration—and reinforces a shared commitment to strengthening the country’s critical infrastructure for generations to come.”

Engineering services for federal government priorities

As part of the consortium, Stantec’s scope will include project management, civil engineering, environmental services, architecture, buildings engineering, power engineering, geotechnical engineering, and landscape architecture.

A validation phase will commence in the first quarter of 2026. Upon validation and the completion of a design development phase, construction is expected to commence.
