AECON PARTNERSHIP EXECUTES AGREEMENT TO DELIVER THE ARCTIC OVER-THE-HORIZON RADAR PROGRAM STAGE 1 PROJECT IN ONTARIO

Aecon Group Inc. has executed a partnership with Pomerleau and Stantec and entered an agreement with Defence Construction Canada to deliver the Arctic over-the-horizon radar program Stage 1 project in Ontario.

Under a collaborative integrated project delivery model, Defence Construction Canada serves as the project owner, and an Aecon-led 50/50 joint venture between Aecon and Pomerleau is responsible for project delivery. 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.

Implemented by Canada's Department of National Defence, the Arctic over-the-horizon radar program is part of a key NORAD modernization initiative that will advance the renewal of Canada's North warning system. The program will establish a northward-aimed radar system with long-range surveillance of the Northern approaches to major population centres in North America.

"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 chief executive officer, Aecon Group.

Further project information is available on the MERX website.
