A year strip of months. Late summer to early fall is the best time to plant, spring is acceptable with a little more risk, and midsummer planting is the greatest risk because the tree may not be watered.
Homeowner question

When is the best time to plant a tree?

The goal is usually to give the tree as much time to establish as possible before summer drought. Therefore, late summer to early fall is the best time of year. Spring is acceptable as well; it just carries a little more risk. Summer planting is the greatest risk to the tree, in part because many Ontarians vacation and the tree may not get watered while they are away.

Before you cut

Greater Sudbury’s private tree rules

No permit needed for private trees

Greater Sudbury does not require a permit to remove trees on your own property. Trees on the road allowance (boulevard) belong to the City and are protected.

Whole city

No private tree permit

No by-law regulates removing trees fully on private land.

Road allowances

Boulevard trees are protected

Under By-law 2011-243, you may not damage, remove or plant a tree on the road allowance without City approval. This includes any tree whose trunk is partly on the road allowance.

Whole city

Requesting City tree work

The City removes street trees that are diseased, dangerous or harming infrastructure. Call 311 to request an assessment.

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.

What’s changing

Rules under review

Council approved an Urban Forest Master Plan on March 25, 2025 that covers private as well as public land; no private tree by-law has been proposed that I could confirm.

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.

Homeowner question

Does it matter when a tree gets pruned?

If the branches are dead or truly hazardous, then to protect your health and safety, it doesn't matter. Do it any time of the year. For live branches it is best done before the spring growth flush, when wounds close the fastest.

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.

Homeowner question

If a tree is rubbing against a house, how far back should it be pruned?

Evergreens typically grow more slowly, so they don't need as much clearance. Most deciduous trees should be pruned back approximately 2 metres (6 to 7 feet) from the house.

We caution against clearing too much from the house side. It can injure the tree and pose a greater risk to your house. For example, if a high branch breaks, there is no lower branch for it to get caught on.
