Tree Trimming & Pruning — For Healthier, Safer Trees.
Proper pruning keeps your trees strong, safe, and beautiful. Our certified arborists trim for tree health — not just looks — clearing roofs, lines, and sightlines without harming the tree.

Good pruning protects the tree. Bad pruning kills it.
Topping and over-cutting are the fastest way to weaken a healthy tree — yet that’s exactly what untrained crews do. Certified pruning removes the right branches, at the right points, at the right time of year.
We prune to improve structure, increase light and air, clear hazards from your home and wires, and shape the canopy — all while protecting long-term tree health.
The result: trees that look better, live longer, and are far less likely to drop a limb in the next storm.
When to book a pruning
- Branches touching the roof, siding, or windows
- Limbs growing into hydro or utility lines
- A dense canopy blocking light to the yard
- Dead, crossing, or rubbing branches
- A young tree that needs structural shaping
- Storm-damaged or hanging limbs
Trimming That Respects the Tree
Every pruning follows ISA best practice — no topping, no lion-tailing, no guesswork.
- Certified pruning cutsProper cuts at the branch collar that seal cleanly and protect the tree.
- Crown thinning & cleaningSelective removal of dead and crowded limbs for light, air, and structure.
- Clearance pruningBranches lifted off roofs, driveways, and utility lines for safety.
- Structural shapingYoung and mature trees shaped for strong, balanced long-term growth.
- Seasonal timing adviceWe prune at the right time of year for each species to avoid stress.
- Full cleanupAll trimmings chipped and hauled away — yard left spotless.
Trimming & Pruning: The Details Homeowners Ask For
Straight answers on timing, permits, access, and what it costs you.
- Best time of year
- Late winter, while the tree is dormant, for most species. Dead and hazardous limbs come off any time of year.
- The oak exception
- Toronto asks that oaks not be pruned between April 1 and October 31. Fresh cuts in the growing season draw the sap beetles that spread oak wilt, confirmed in Ontario since 2023.
- Toronto permit
- None for pruning done to good arboricultural practice. Cutting beyond that counts as injuring the tree under Chapter 813 and needs an injury permit once the trunk is 30 cm or wider.
- How much comes off
- No more than a fifth to a quarter of a mature canopy in a single visit. Anything past that starves the tree of the leaf area it lives on.
- The four standard cuts
- Crown cleaning takes out dead and broken wood. Crown thinning opens the canopy to light and wind. Crown raising lifts the lowest limbs off the roof or driveway. Crown reduction shortens the whole crown back to a lateral branch.
- Typical job length
- Two to four hours for one mature maple. A full front yard of established trees takes a day.
What a certified pruning cut actually looks like
Every cut lands just outside the branch collar, the slight swelling where a limb meets the stem. That collar holds the chemistry a tree uses to wall off a wound, so a cut placed outside it seals over in a season or two. A flush cut removes the collar and leaves a hole the tree cannot close, which is the difference between a pruned tree and a damaged one.
Reduction works the same way. To shorten a limb we cut back to a side branch at least a third the diameter of the wood being removed, so a living leader takes over the flow. Topping ignores that rule, leaves blind stubs, and the tree answers with a burst of weak shoots attached to dead wood. Those shoots are what fail in the next windstorm.
Timing matters more on some species than others. Maples and birches bleed sap from late-winter cuts, which looks alarming and harms nothing. Elms and oaks are the ones with a hard calendar: fresh wounds in warm weather attract beetles carrying Dutch elm disease and oak wilt, so those trees get pruned in the cold months unless a limb is an active hazard.
We do not paint or seal cuts. Wound dressings trap moisture against the wood and slow the tree’s own compartmentalisation. The single exception is an oak that has to be cut during the risk window, where a thin coat over the fresh wound keeps beetles off it.

Questions Homeowners Ask Us
When is the best time to prune my trees?
For most species, late winter to early spring (when dormant) is ideal, but dead or hazardous limbs can be removed any time. We’ll advise the right timing for your specific trees.
Will pruning hurt my tree?
Done correctly, no — proper pruning improves health and structure. The damage comes from topping and over-thinning, which we never do.
How much should I prune off?
Generally no more than 20–25% of the canopy at once on a mature tree. We remove only what benefits the tree and your safety.
Can you prune branches away from my roof and gutters?
Yes — clearance pruning to keep limbs off the roof, siding, and gutters is one of our most common requests.
Do you clean up afterwards?
Always. All branches are chipped and hauled away and your yard is left clean.
Do I need a permit to prune my own tree in Toronto?
Not for routine pruning done to good arboricultural practice, which the bylaw exempts. Cutting past that standard can count as injuring the tree, and injuring a protected private tree with a trunk 30 cm or wider needs a permit under Chapter 813.
Why can’t oaks be pruned in summer?
Oak wilt was confirmed in Ontario in 2023 and spreads to healthy oaks through beetles drawn to fresh cuts. Toronto asks that oaks not be pruned from April 1 to October 31 for that reason. Red, black and pin oaks are the most vulnerable; white, bur and swamp oaks resist it better.
Should the cuts be painted afterwards?
No. Sealants hold moisture against the wound and slow the tree’s own defences. The exception is an oak pruned during the growing season, where a light coat keeps sap beetles away from the fresh cut.
My maple is dripping sap after pruning. Is it dying?
No. Maples, birches and walnuts bleed from late-winter cuts because root pressure is pushing sap upward before the leaves open. It stops when the canopy fills in and does the tree no harm.
