Trees and power lines don’t get along.  

Trees are a significant cause of local power outages. Outages are caused from branches rubbing or falling on power lines, and trees falling across power lines during storms. 

In stormy weather, sometimes there are multiple areas where trees have come into contact with power lines.  This causes delays in finding every trouble spot and longer outages for you and your neighbours.

For properties that contain utility easements, we request that homeowners not plant trees or otherwise encroach on easements in a manner that will limit access or interfere with operation of the power lines. 

Homeowners are responsible for vegetation under their private service lines

Local utilities have the responsibility to keep trees trimmed under their main power corridors and within the municipal easements.

Homeowners are responsible for all the trimming and tree and brush removal for the property  around private overhead service lines that link their home or business to our primary service lines.

Due to the danger of overhead power lines, unqualified individuals should never attempt to cut down trees or trim branches close to, or touching any overhead lines.  We strongly recommend that you hire a certified utility arborist or qualified electrical contractor to work under service lines.

To accommodate tree trimming under a service line, Thunder Bay Hydro will provide a free service disconnect/reconnect. (Limited to one per year) 

We will only remove trees under a service line when these trees could fall into the utilities main power line and create a hazard.

Plant the Right Tree in the Right Place

Homeowners can avoid service interruptions, help reduce costs and maintain a pleasant environment by ensuring trees of the correct size and species are planted near power lines. Do not plant trees that will grow tall near power or communication lines. Chose only low growing compact species.  Save tall trees for areas farther from power lines.

When you are looking for landscaping options, remember to consider height and location.  Look at the 'mature' height of the tree or shrub when considering a species for your landscaping near power lines.





Examples of low-growing trees appropriate for Northwestern Ontario:

  • Amur Maple
  • Tatarian Maple
  • Goldrush Chokecherry
  • Starlite Crabapple
  • Dwarf Apple
  • Dogwood
  • Japanese Tree Lilac
  • Russian Mountain Ash

Caution! Different species within the same 'named' tree group can grown to different heights. Always check mature height expectations before choosing a tree for the LOW ZONE.  Consult with your local nursery for other options.

The City of Thunder Bay outlines both large and small stature trees that are being used locally on their website.
