Space Weather Station – Churchill Falls NL

The Department of National Defence (DND) has proposed a project. DND intends to install four unoccupied Space Weather Stations consisting of one or more Transmit and/or Receive antennae, a small shelter in which to house the hardware, and a perimeter fence. They will form part of a network of such installations that will collectively measure real-time fluctuations in the ionosphere (i.e. space weather) in order to map it as a reflecting surface for high-frequency radio signals.

This information will be used as part of Canada's Arctic Over-The-Horizon Radar project.

Latest update

September 3, 2026 - Environment and Climate Change Canada has been added as a Federal Authority for the project due to potential responsibilities under the Species at Risk Act. The authorities intend to make a determination regarding whether the carrying out of the project is likely to cause significant adverse environmental effects. To help inform this determination, the authorities are  inviting public comments until September 25, 2026 respecting that determination.
