If you notice a tree that is interfering with our power lines or poses a hazard, report it to 1-800-434-1235.


Hazardous conditions may include:

  • The tree or branches are smoking, sparking, or burning on a power line

  • The tree is an immediate hazard to the line (split, leaning, hanging over, uprooted)

  • The tree is leaning on a hydro pole.

Do not attempt to prune or cut down a tree near power lines. A tree falling onto a power line can cause serious injury or death.

Who is responsible?

We are responsible for vegetation management on road allowances, but not tree trimming or maintenance of trees and vegetation on customer property. This is the responsibility of the owner. See the diagram below to see the difference between our power lines and privately-owned lines.


Our Power Lines:

  • Usually run along the road

  • Not on private property

  • Service multiple customers.


Privately-owned Power Lines:

  • On a pole within your property’s boundary

  • The pole supports overhead power lines to your home/other buildings on your property

  • Does not supply power to other customers.

Caring for your property

We recommend that you hire a qualified contractor to do vegetation management work near privately-owned power lines and contact us to temporarily disconnect your electrical service during maintenance. We will temporarily disconnect your electricity service for free once a year.

If trees on your property have grown close to power lines on the road allowance, please contact us at 1-888-664-9376.

 

Service requests

If you would like work done on a tree close to our power lines, call us at 1-888-664-9376 or submit a service request online through myAccount. We will assess the situation and determine the appropriate action.

 

Pick the right plants, pick the right place

When planting trees on your property, avoid planting trees near any power lines or electrical equipment, such as poles, to ensure newly planted trees and shrubs never interfere with nearby power lines or electrical equipment.

If a tree must be planted near a power line on your property, first check with your municipality to ensure all by-laws are followed and that any easements on your property are respected.
 

Call before you dig

If you are planning any yard work, such as planting trees, contact Ontario One Call to request cable locates to confirm there is no underground equipment, such as cables, in the area you intend to dig. 

We will visit your property and mark any locates free of charge. Please provide at least five business days’ notice. If there is a cable locate, we recommend selecting a more suitable area with a minimum of 3 metres distance away from the identified equipment.

To request a locate, call 1-800-400-2255 or submit an e-ticket at Ontario One Call.
 

Staying safe

For power lines for which you are responsible, be sure to use the help of qualified arborists only and keep in mind these potentially fatal mistakes:

  1. Cutting a branch near a power line. This may bring it too close to the line as it falls and may cause an arc flash that could cause serious injury or death.

  2. Cutting down a tree that could fall in the proximity (less than 10 metres) of a power line. Only professional arborists can expertly control which way a tree will fall when cut. Without proper planning and execution, this may cause the tree to fall onto or too close to the line, causing major damage to our equipment and can cause serious injury or death.

  3. Electricity always wants to return to ground and it does not care how it gets there – it takes the path of least resistance. Using tools such as ladders or long-handled pruning shears too close to a power line could cause the current to run through the tool and potentially cause serious injury or death.
