Ties are broken by number of credentials (each Certified Arborist, Board Certified Master Arborist and Tree Risk Assessment Qualification holder counts, so someone with two counts twice), then Google reviews. Virgin Tree Care and CE Tree Services are tied at 4/10 leaves.

The same tree twice. In winter with the leafs off, an arborist sees the branch structure, joints, cracks and dead limbs. With the leafs on, they see leaf health, dieback and pests.
Homeowner question

Should an arborist assess a tree with the leafs on or off?

Both views have their pros and cons. In the winter an arborist can see the overall structure of the tree better. If there are splits in branches, we can see them more clearly. The downside is that sometimes it is a little harder to see which branches are dead or alive.

Bottom line: if you think your tree needs to be assessed, don't let the time of year stop you from reaching out to an arborist.

Before you cut

Ajax’s private tree rules

Permit needed in some areas or cases

Ajax does not require a permit to remove a tree on a typical house lot. Permits are needed only for trees on park, greenbelt and environmental protection lands, and boulevard trees are protected.

Mapped areas only

Protected lands need a permit

Tree Protection By-law 137-2006 bans damaging or removing trees without a permit on Parks, Greenbelt and Environmental Protection lands.

Standard lots

Typical yards are not covered

The Town does not regulate tree removal on ordinary residential lots outside those lands. The Town removes trees only on municipal property.

Town-owned trees

Boulevard trees are protected

Boulevard Tree Protection By-law 65-2021 protects Town trees on boulevards. Contact the Ajax Operations Centre for inspections or to request a street tree.

Whole town

Rebate for caring for big trees

The Mature Tree Conservation Program rebates about 25% of care costs, up to $1,000, for private trees 40 cm or wider measured 1.4 m off the ground.

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.

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.

Summary checked September 2026. It’s a plain-language guide, not legal advice. Bylaws change, so confirm with the municipality before you remove a tree.

Sources
A year strip of months showing the dormant season as best for pruning live branches, the spring growth flush as the time to avoid heavy pruning, and dead or hazardous limbs removable any time.
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.

A gutter with a guard on top. Wet leafs pile up on the guard and carry rain water over the front edge of the gutter instead of into it, so guards still need to be cleared from time to time.
Homeowner question

Do gutter guards work against leafs?

They can help, but it is important to understand that they are not a cure-all. Having a gutter guard does not mean the gutters will never need to be inspected and cleared of leafs from time to time.

This is particularly the case when leafs get wet and accumulate. The leafs can sit on the gutter guard and act as a bridge, carrying the water right over the top of the gutter.
