Aecon, Pomerleau, Stantec partnership to deliver Arctic Over-the-Horizon Radar project

TORONTO – A partnership between Aecon, Pomerleau and Stantec has executed an agreement with Defence °µÍø½ûÇøion Canada to deliver the Arctic Over-the-Horizon Radar Program (A-OTHR) Stage 1 project that will be located in Ontario.

Essentially, the project involves providing long-range, early-warning radar coverage of the country’s northern regions.

Aecon and Pomerleau will provide construction services as a joint venture, and Stantec will undertake multidisciplinary project management and design services.

According to a release, the A-OTHR system is part of a federal investment implemented by Canada’s Department of National Defence to modernize North American Aerospace Defense Command (NORAD) infrastructure, which is a network of sensors, command centres 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.

The project is being delivered under an Integrated Project Delivery model, where Defence °µÍø½ûÇøion 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, the release notes. Upon validation and the completion of a design development phase, construction is expected to commence.
