Trees and power lines
Why tree maintenance matters
Trees are an important part of our city. Making sure they don’t contact wires is important to help avoid outages and injuries.
Trees and branches are good conductors, this means that they only need to come close to a wire for electricity to arc, or 'jump' and travel through them and cause a shock or a fire.
If your trees contact your service line, we recommend you call a trained arborist to trim your trees. To avoid problems from growth, plant new trees away from lines.
Tree Trimming Program
Our crews survey neighbourhoods on a three-year cycle to identify trees and branches that are too close to the wires that run from pole to pole in public areas such as parks or along roads and back lanes. We do this to keep our crews safe while working on the wires and to help avoid outages.
