Aecon Group (TSX:ARE) has signed a partnership with Pomerleau, Stantec (TSX/NYSE:STN) and Defence Construction Canada to advance Stage 1 of the Arctic Over-the-Horizon Radar Program in Ontario—an initiative tied to Canada’s broader NORAD modernization strategy.

The project will be delivered under an Integrated Project Delivery (IPD) model, designed to enhance collaboration, transparency, and shared responsibility throughout the project lifecycle. Defence Construction Canada will serve as the project owner, while an Aecon‑led 50/50 joint venture between Aecon and Pomerleau will be responsible for project execution. Stantec will provide design and engineering expertise.

A validation phase is scheduled to begin in Q1 2026. After validation and completion of design development, construction is expected to commence.

The Arctic Over-the-Horizon Radar Program—implemented by Canada’s Department of National Defence—forms a key element of the modernization of North America’s defence infrastructure. The program aims to renew and enhance Canada’s North Warning System by establishing a northward‑aimed radar array capable of long-range surveillance across the northern approaches to major population centres. This enhanced early-warning capability is expected to strengthen continental security and support NORAD’s mission in detecting and tracking potential aerial threats.

“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,” Aecon’s president and CEO, Jean-Louis Servranckx said in a news release.

Aecon Group stock (TSX:ARE) last traded at C$37.33 and has risen more than 60 per cent since this time last year.

Aecon Group Inc. provides construction and infrastructure development services to private and public sector clients in Canada, the United States, and internationally.
