Aecon, Pomerleau JV to build Arctic long-range radar system

Key Takeaways:

• Aecon and Pomerleau formed a joint venture to build a new long range radar system for northern surveillance.
• This project is part of a larger effort to modernize NORAD and the aging North Warning System.
• A validation phase starts in the first quarter of 2026 before design and construction begins.

The Whole Story:

Aecon Group Inc. has been selected through a partnership with Pomerleau and Stantec to deliver Stage 1 of the Arctic Over-the-Horizon Radar Program in Ontario under a collaborative Integrated Project Delivery model, with Defence Construction Canada serving as project owner.

The Aecon-led 50/50 joint venture between Aecon and Pomerleau will manage project delivery. A validation phase will begin in the first quarter of 2026, followed by design development before construction commences.

The Arctic Over-the-Horizon Radar Program, implemented by Canada’s Department of National Defence, is part of a NORAD modernization initiative to renew the North Warning System. The project will establish a northward-aimed radar system providing long-range surveillance of northern approaches to major North American population centres.

“Aecon is purpose-built to deliver complex projects with national importance. The Arctic Over-the-Horizon Radar Program is a critical undertaking and Aecon is primed to play a central role in delivering this essential defence infrastructure project alongside Defence Construction Canada and our partners,” said Jean-Louis Servranckx, president and CEO of Aecon Group Inc.

Pomerleau president and CEO Philippe Adam said the project arrives at a pivotal moment for Canadian defence infrastructure.

“Pomerleau is honored to contribute to this nation-defining initiative that strengthens Canada’s defense capabilities,” Adam said. “It reinforces our role as a trusted partner in delivering complex infrastructure, at a time when national demand for these capabilities is rapidly increasing. Working hand in hand with our client, the Government of Canada, and our partners we are fully engaged in delivering this ambitious project through seamless collaboration, technical excellence and innovation.”

The program represents a key infrastructure investment in Canada’s defence capabilities and northern security posture. The Integrated Project Delivery model emphasizes collaboration among all parties to optimize scheduling, cost management and risk allocation across design, procurement and construction phases.

Stantec president and CEO Gord Johnston said the project builds on a longstanding relationship with the federal government.

“We are honored to help advance NORAD’s modernization, drawing on our deep experience in delivering resilient, climate‑ready solutions across Canada,” Johnston said. “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.”
