Tree Pruning in South Ontario

How it works

1. Walk the property with you and identify which trees need work and why
2. Quote each tree separately so you can choose the scope and budget that fits
3. Climb or use a pole saw and pole pruner depending on the height and reach of the cut
4. Prioritize dead, diseased, broken, and crossing branches, then shape and thin as needed
5. Use the three-cut method on larger limbs to prevent bark tearing, and cut back to the branch collar so the tree heals cleanly
6. Chip or haul the debris based on your call and leave the site clean

Good for

• Mature shade trees that have not been pruned in 5 or more years
• Branches overhanging the house, driveway, deck, sidewalk, or pool
• Young trees that need structural pruning to set up good long-term shape
• Dead, diseased, or broken wood that should come out before it falls
• Crown thinning to let more light through to the lawn or garden below
• Fruit and ornamental trees that have grown dense and need opening up
• Trees that have outgrown their space and are crowding a fence or structure

When to do this work

For most deciduous trees in southern Ontario, the dormant season from late fall through winter (roughly November to March) is the best time to prune. With the leaves down the branch structure is easy to read, and most insects and disease organisms are inactive, which lowers the risk of infection through fresh cuts. Dead, broken, or diseased wood can be taken out at any time of year and does not have to wait for dormancy. A few exceptions matter: maple, birch, and other heavy sap producers will bleed if cut in late winter or early spring, which looks messy but does not harm the tree, and they can be pruned in early summer instead if you want to avoid it. Spring-flowering trees like lilac, magnolia, and crabapple are best pruned right after they finish blooming, since they set next year's buds the previous summer. Oaks are the strict one: to reduce the risk of oak wilt, oaks should not be pruned during the growing season, so we keep oak work to the dormant window (roughly November through March) unless a branch is broken and has to be dealt with for safety.

For the full seasonal breakdown, see our guide on when to prune trees in southern Ontario, which covers the dormant season, sap bleeders like maple and birch, and oak wilt timing. Oaks run on their own calendar, so we break down exactly when to prune oak trees in Ontario.

Where we work

Tarzan Trimming is mobile and owner-led, covering Toronto, Mississauga, Oakville, Burlington, Hamilton, Kitchener, and Whitby. See the areas we serve across south Ontario for what to expect in your town. We are a small operation by design, so every job gets the same attention.

Removing a protected tree? Check the permit rules first

Across the GTA corridor most cities protect larger private trees, and you usually need a permit, often with an arborist report, before a protected tree comes down. We focus on pruning and limb removal rather than full removals, but if you are weighing whether a tree should come out, it pays to know your city's bylaw before you start. We have written plain-language guides for Toronto, Mississauga, Oakville, and Burlington.
