Radar Visibility Maps in Canada

The map below shows the location where wind turbines could be visible to Environment Canada's radars. This information may assist industry in identifying potential turbine locations.

Regional and local scales of these maps are available by clicking on an area of interest.

How to View the Map

The radar site locations are marked with a black dot. A green circle shows a 50 kilometre radius around the radar.  Inside this 50 kilometre ring, potential interference with the radar may exist and direct consultation is strongly suggested. Major roads and cities are indicated in dark blue.

The colour display surrounding the radar(s) represents whether wind turbine blades could be seen by the respective radar (in yellow) and if the wind turbine towers can be seen (in red). The visibility maps have been created for turbine models with turbine tower heights of 100 meters and blade lengths of 50 meters (for a total blade height of 150 meters). If any part of a turbine is visible to a weather radar, interference is expected, but if the turbine tower is visible (in red) more severe impacts may occur. Any region not covered by the colour display indicates that a wind turbine with a total height of 150 meters should not be visible to the radar. However, a turbine with a blade height greater than 150 meters may be seen and further analysis is necessary.
