Before you cut

Halton Hills’s private tree rules

No permit needed for private trees

Halton Hills has no bylaw requiring a permit to remove a tree on your own lot. Town-owned boulevard trees are handled by the Town, and woodlands over 0.5 hectare fall under Halton Region's tree bylaw.

Private property

No private tree permit

The Town has not passed a private tree bylaw. You do not need a Town permit to remove a tree on a typical house lot.

Town-owned trees

Boulevard trees belong to the Town

The Town maintains trees on public property, including boulevards. Contact Transportation and Public Works about a Town tree instead of cutting it yourself.

All of Halton Region

Woodlands over 0.5 hectare

Halton Region's Tree By-law 121-05 covers properties with woodlands larger than 0.5 hectare or land in the Regional natural heritage system. Cutting there needs a Regional permit, with exemptions for dead or diseased trees and normal farming.

Future

Private tree bylaw studied, not passed

The Town's Privately-Owned Tree Management Strategy recommends considering a private tree bylaw after more public consultation. That consultation has closed, and no bylaw has been passed.

Anywhere in Ontario

Trees on a property line

A tree whose trunk sits on the line belongs to both neighbours. Ontario’s Forestry Act says you need your neighbour’s consent before removing or injuring it.

Size limits, fees, replacement trees and exemptions
Common exemptions
  • Regional by-law exempts dead or diseased trees, normal farm practices, and removals approved through other processes such as development applications.
What’s changing

Rules under review

Privately-Owned Tree Management Strategy (draft) recommends a possible future private tree bylaw after further consultation; no council date or draft bylaw found as of 2026-09.

Not sure if you need a permit?

Ask the municipality before any work starts. A good tree company will also check for you and tell you who applies for the permit.

Before you hire

What to check before you hire a tree service

Tree work is dangerous, and it’s expensive to fix when it goes wrong. Six questions worth asking any company, including the ones on this page.

  1. Ask for a WSIB clearance certificate and proof of liability insurance

    Tree work is one of the most dangerous jobs out there. We do our best on our end, but these certificates can change before we have a chance to update them. Some good companies will give them to you without you even having to ask. Bonus!

  2. Find out who will actually do the work

    You may get a Certified Arborist as your salesperson, but will the same be true of the person who works on your property? You won't know until you ask. A Certified Arborist may cost more, but it can cost a lot more if the work is done wrong and the tree dies early or your property is damaged.

  3. Get the quote in writing

    It should say exactly which trees, and whether cleanup, wood removal, stump grinding and so on are included. The more detailed the quote, the better.

  4. Ask who handles the permit

    If a bylaw applies, agree up front who applies for the permit and who pays the fee. Removing a protected tree without one usually means a fine for the property owner, not the tree company.

  5. If money is tight, try this

    See if the work can be scheduled in a slower season for a lower price. Clear obstacles (fences, gates, lawn ornaments, plants) before the crew arrives. Find someone online, such as on Facebook Marketplace, who will take the wood for free. Or change the scope of work, for example pruning only the lower half of the tree instead of the whole tree.

  6. Trees near power lines are a utility job

    If branches touch or come close to a hydro line, call your local hydro utility (the one on your electricity bill) first. Only crews the utility approves can work near power lines.

How we pick Halton Hills’s top 3

We rank every company whose service area includes Halton Hills by ARB Score.
