If there’s a fire or someone is in danger, call 911.

Please answer the question below and any others that may come after it. Your answers will help us determine whether we need to do anything. We only do the work needed to keep people safe or avoid an outage.
Is it one of these situations that concerns you?
  • A tree or big branch is leaning on a wire.
  • A tree or big branch looks like it may fall onto a wire.
  • A climbing plant is twining around a wire.
  • There are sparks or arcing between branches and wires.

Safety warning

LOOK UP FROM THE GROUND. STAY AWAY FROM THE WIRES AND DON’T LET ANYBODY OR ANYTHING (TOOL, LADDER, TAPE MEASURE OR ANYTHING ELSE) GET WITHIN 3 M OF THEM.

What type of lines are they? Select the picture that looks like most like the situation that concerns you, then click on Continue at the bottom of the page.

You have selected MEDIUM-VOLTAGE lines.

Safety warning

Stay away from the wires and don’t let anybody or anything (tool, ladder, tape measure or anything else) get within 3 m of them.

You have selected low-voltage lines.

Low-voltage lines (120–600 V) are a serious shock hazard, even though they have an insulating sheath, because they can carry thousands of amps. As a precaution, never touch them directly or indirectly, because the sheathing may be damaged, even if it doesn’t look like it.

Do you see either of these situations?
  • The three stacked wires are bare.
  • The sheathing is obviously damaged.

Safety warning

If the three stacked wires are bare, or if the insulating sheath is obviously damaged, stay away from the wires and don’t let anybody or anything (tool, ladder, tape measure or anything else) get within 3 m of them.

For safety reasons, the law requires trees in such situations to be pruned or felled by arborists authorized by Hydro-Québec.

Is the tree or branch that concerns you also close to a wire at the top of the pole?

Safety warning

If the branch or tree that concerns you is also close to wires at the top of the pole, don’t climb the tree to prune it: it’s the same as going near the wires yourself. Those are medium-voltage wires. They are NOT covered by insulating sheaths and their voltage may be as high as 25,000 V.

For safety reasons, the law requires trees in such situations to be pruned or felled by arborists authorized by Hydro-Québec.

Your answer indicates that there’s no need for Hydro-Québec to take any action.

Low-voltage lines are usually insulated and have a voltage of 120 to 240 V (sometimes up to 600 V). As a precaution, stay away from them, because if the sheathing is damaged or cracked, you could receive a very serious shock.

If you want to prune or cut down a tree near this type of wire, we recommend you call an arborist who is a member of SIAQ (Société internationale d’arboriculture Québec, the Québec chapter of the International Society of Arboriculture).

Thank you for helping keep your neighborhood safe.

You have selected telecommunications wires.

Telecommunications wires are not an electrical hazard, because they are sheathed and have a voltage of approximately 12 V.

The situation that concerns you does not require Hydro-Québec to take any action.

If a tree looks like it may damage the wires, notify the telecommunications company.

Thank you for helping keep your neighborhood safe.

  • Safety warning

    Don’t touch the plant and never try to get it off the wire. This situation is extremely dangerous.

Please provide some contact information so that we can follow up with you or obtain additional information.

Are you a Hydro-Québec customer?
Are you the owner of the tree posing a problem?

Hydro-Québec will assess the situation based on the information you have provided and will contact you if necessary. Of course, we will take action in cases of immediate risk. However, if the risk is not imminent, we remind you that only the owner of the tree may request a trimming service and will have to cover the cost. If the tree is not pruned following your request, the medium-voltage lines will be cleared during preventive work carried out periodically by Hydro-Québec.
