Canada’s Department of National Defence (DND) has acquired 451 hectares of land in Ontario for its new Arctic Over-the-Horizon Radar (A-OTHR) project.

The project is part of the Canadian government’s bid to modernize its contribution to continental defence through the North American Aerospace Defense Command (NORAD).
