Mississauga’s private tree rules

Permit needed across the city

In Mississauga you need a City permit to remove or damage any private tree with a trunk 15 cm (6 inches) or wider, measured 1.4 m off the ground. City-owned trees can't be pruned, damaged or removed without a permit.

Whole city

Private trees 15 cm and up need a permit

A permit is needed to injure or remove any private tree 15 cm or wider, measured 1.4 m off the ground. Dead or dying trees (including all ash trees) still need a permit, but there is no fee.

Whole city

Plant a new tree for every 15 cm removed

You must plant one replacement tree for every 15 cm of trunk removed, and pay a security deposit that is returned after a one-year check.

City-owned trees

City trees: permit even to prune

Under the Public Tree Protection By-law you cannot injure, remove or prune a City tree without a permit. Call 311 about boulevard trees.

All of Peel Region

No separate regional tree by-law found

We found no Peel Region-wide tree or woodland by-law; Mississauga's own by-laws apply.

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.

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 Mississauga’s top 3

We rank every company whose service area includes Mississauga by ARB Score. The score counts Google reviews, WSIB clearance, published insurance and pricing, years in business, ISA-verified arborists and Canadian ownership. We look up everything except insurance and pricing, which a company tells us itself.
