Before you cut

Whitby’s private tree rules

Permit needed in some areas or cases

Most regular house lots in Whitby do not need a permit to remove a tree. A permit is needed in woodlots, natural or hazard-land zones, heritage districts, and on residential properties of about 5 acres (2.02 ha) or more.

Mapped areas only

Where a permit is needed

Tree Protection By-law 4640-00 applies to woodlots of 0.2 ha or more, Major Open Space, Hazard Land and environmental protection lands, mature woodlands and sensitive areas, heritage districts, and trees in approved tree preservation plans.

Large lots

Residential lots 2.02 ha and up

Residential properties of 2.02 ha (about 5 acres) or more in the zones listed in the by-law also need a permit.

Standard lots

Typical yards are exempt

If the wooded area on your lot is under 0.2 ha, you are outside a heritage district, and there is no approved tree preservation plan, no permit is needed.

Town-owned trees

Street and park trees are protected

Under the Clean Community By-law, no one may injure or remove trees on Town property, including street and park trees. Driveway widening or planting on the boulevard needs Town approval.

All of Durham Region

Woodlands 1 ha and larger

Durham Region's Woodland By-law 30-2020 requires a Region permit to cut in woodlands of 1 ha (2.5 acres) or more.

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
Replacement trees
Permit conditions may set the species, size, number and location of replacement trees and a planting deadline.
Common exemptions
  • Wooded areas under 0.2 ha outside heritage districts
  • Dead, diseased or hazardous trees certified by a person approved by the Director
  • Storm or disaster damage
  • Up to 20 trees a year for the owner's personal use
  • Orchards and tree farms
  • Trees needed for authorized building construction

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.
