Our Services - Tree Trimming/Removal

Have you noticed a tree that's interfering with power lines?
At Hydro One Networks, it's our job to maintain and repair all the power lines that make up our transmission and distribution system. Maintenance includes tree and vegetation trimming/removal and emergency repairs along Hydro One power lines.

If you notice a tree that's interfering with the lines, please call our emergency line at 1-800-434-1235. Contact us if the tree poses a potential threat to human safety or meets any of these hazardous conditions:

1. The tree or branches are smoking, sparking or burning on a hydro line
2. The tree is an immediate hazard to the line (split, leaning, hanging over, uprooted)
3. The tree is leaning on a hydro pole.

Do not attempt to prune or chop down a tree near lines yourself; a tree falling onto a power line could cause serious injury or death.

Privately owned lines
Hydro One Networks is not responsible for the maintenance of trees or vegetation on privately owned lines; that is the responsibility of the owner. We recommend that you hire a qualified contractor to do the work and contact us to temporarily disconnect your electrical service during maintenance.
