Tree Down After a Storm in Ottawa: What to Do First

If a tree comes down in a storm, get everyone away from it, treat every wire as live and call Hydro Ottawa if a line is touched or sagging. Then photograph the damage and call a tree crew for anything on a house, car or fence or blocking your driveway. Do not cut it yourself. Bisson Services has 24-hour emergency service, so call 613-558-4806 or see tree cutting and removal.

The first hour: safety before anything else

  • Get people and pets away from the tree, and out of any room under a tree that is on the roof.
  • Stay well back from any wire. Treat every downed or sagging line as live, even if it is not sparking, and call Hydro Ottawa.
  • If anyone is hurt or a wire is down on a car, call 9-1-1.
  • Do not climb on the tree or step under anything hanging in the crown. Hung limbs can drop later, with no warning.
  • Wait until the wind has dropped before you go outside to look.

Then document it

Take wide and close photos from several angles before anything is moved: the tree, its base, the ground around it and any damage to the house, fence, car or shed. Call your insurer early and ask whether they need to see the damage before work starts. Keep every receipt. We cannot say what a policy covers.

What can wait and what cannot

Call now: a tree on or against a building, anything touching a wire, a tree blocking your driveway or the road, a trunk that is cracked or splitting, a fresh lean with soil lifting, or a limb hung up over a house or play area.

Can wait for an appointment: small branches on the lawn, a tree that was already dead and has shed some bark, and cleanup of leaves and twigs.

Why not cut it yourself

A fallen or half-fallen tree is under tension from its own weight, the root plate that is still partly attached and whatever it rests on. None of that is visible, and it releases fast when cut. Storm injuries often happen to people working alone with a chainsaw or a ladder. Leave anything leaning, hung up or under load to a crew.

City trees and your own trees

A tree on the City boulevard or in a park belongs to the City of Ottawa: report it to 3-1-1. For your own tree, Ottawa's Tree Protection By-law allows removal without a permit when a tree is an immediate threat to public health and safety. The City asks you to photograph it first. Our guide to the tree removal permit rules has the details.

What the crew will do

On an emergency call the aim is usually to make the hazard safe and get access open first, then finish the cleanup. Bisson Services provides 24-hour emergency service for dead, dying and dangerous trees across Ottawa and Prescott-Russell. If other trees on the property worry you after the storm, read how to tell if a tree is dangerous, or ask for a free estimate on tree removal or pruning.

Common questions

What do I do first when a tree falls in a storm?

Get everyone away from the tree, stay clear of any wires and call Hydro Ottawa if a line is touched or sagging. Then photograph the damage and call a tree crew.

Can I cut up a fallen tree myself?

We advise against it. Fallen and partly fallen trees are under hidden tension and can move suddenly when cut. Call a crew.

Who do I call if a tree is on a power line in Ottawa?

Hydro Ottawa. Stay well back and treat any downed line as live.

Do I need a permit to remove a tree that fell in a storm?

A tree that is an immediate threat to public health and safety does not need a permit; photograph it first. See our permit guide for the rest.
