Street lights and Traffic control signals

Street lights

With over 5,000 street lights across the City of Cornwall, the municipality appreciates the help of its residents when identifying street lights that are in need of service. The City has contracted Dundas Power Line LTD. to maintain street lighting.

What types of problems can occur with street lights?

The most typical type of problem that occurs is a burned out street light. Another common problem is when lights cycle incorrectly, meaning they can either flicker or turn on and off randomly. Some of the other types of issues that come up are when lights do not shut off during the day, poles are damaged or a series of lights are not turning on.

How to report a street light outage or down pole?

If you encounter a street light that is not in proper working order or is damaged, please contact Dundas Power Line LTD:
