Ash tree removal in Ottawa requires specialized expertise because these trees, killed by the emerald ash borer, become structurally unpredictable and dangerous. The wood becomes brittle, branches fail without warning, and the tree can shed limbs during the removal process itself. Our ISA Certified Arborists have removed hundreds of ash trees across Ottawa and the surrounding municipalities since 2013, using proven rigging techniques to bring them down safely in confined residential spaces. Whether your ash is in a ravine lot, a tight backyard, or near hydro lines, we assess the hazard, plan the safest descent route, and clean up completely.

Why Ash Tree Removal Matters in the Ottawa Area
The emerald ash borer has decimated ash populations across in Ottawa and the surrounding area. Once infected, an ash tree declines rapidly, losing branches and developing a hollow, weakened trunk within a few years. A dying ash is not simply an eyesore; it becomes a liability. Branches break unpredictably during storms, trees can topple onto homes or vehicles, and the wood becomes too unstable to prune safely. Waiting for the tree to fail on its own invites injury and property damage. Removing it proactively protects your family and your neighbours.
- We assess whether your ash is still viable or condemned by disease.
- We plan the removal to minimize disruption to your property and nearby structures.
- We use professional rigging and climbing to control the descent of heavy limbs.
- We chip all wood on site and haul away stumps, leaving your lot clean.
- We document the work for insurance and municipal permit applications if required.
This proactive approach saves you money and stress in the long run. Removing a hazardous ash before it fails is far cheaper than repairing a collapsed tree or a damaged roof.
Local reality: Surveys across Ottawa neighbourhoods show that one in three mature ash trees are now in decline or already dead from the emerald ash borer. Properties with multiple ash trees often require removal of at least one within five years. Early action prevents emergency calls during storms.
How We Remove Ash Trees Safely
Ash tree removal is not the same as felling a healthy oak or maple. The wood is unpredictable, the tree is often already weakened by disease, and the risk of branch failure during the cut is high. Our process prioritizes safety, precision, and clean-up. We send an ISA Certified Arborist to evaluate the tree first, then dispatch a crew with the right equipment and experience.
- We inspect the ash for structural defects, hollow sections, and remaining branch load.
- We plan a rigging strategy that lowers large limbs safely to the ground rather than dropping them.
- We use professional climbing gear, pulleys, and ropes to control each section as it comes down.
- We cut the trunk into manageable pieces and remove or chip them on site.
- We grind the stump flush with the ground or remove it entirely if requested.
- We haul away all debris or arrange for wood chipping and mulch delivery.
The entire process is quieter, safer, and more controlled than allowing a weakened ash to fail naturally. For tall trees or those near structures, rigging adds time and cost, but it is the only responsible method.
Example from Nepean: An 18-metre ash with a hollow trunk and large dead branches over a garage required four hours of rigging work, two climbers, and a crane assist. Cost was $1,850. Without rigging, a dropped limb would have caused $15,000 in damage. The homeowner also obtained an arborist report to support a permit application with the City of Ottawa.
Removal Methods and When to Use Each
| Method | Description | Best For |
|---|---|---|
| Full rigging with climbers | Arborist climbs the tree, cuts limbs one at a time, and lowers them with ropes and pulleys to the ground. | Tall trees (over 15 metres), trees near houses, garages, or hydro lines, and all trees with structural defects. |
| Directional felling | Tree is cut at the base and guided to fall in a safe direction, then bucked into pieces on the ground. | Open lots with clear fall areas, no nearby structures, and trees with sound wood structure. |
| Section removal with crane | Large sections are cut and lifted away by a mobile crane, avoiding contact with the ground or structures. | Very tall or heavy ash trees in tight spaces, ravine lots, or when ground access is limited. |
| Stump grinding | After the tree is down, the remaining stump is ground out to 15 to 30 centimetres below grade, allowing replanting. | All ash removals; allows you to reclaim the space for landscaping or new plantings. |
Your specific ash removal method depends on tree height, proximity to structures, soil conditions, and access. We assess all factors during the free estimate and recommend the safest, most cost-effective approach.
Permits and Safety Compliance in Ottawa
The City of Ottawa may require a permit for private ash tree removal, depending on the tree's size and location. If your property is in a protected ravine or if the ash is a significant size, a permit is likely necessary. We help you navigate this process. An arborist report and risk assessment documents the tree's condition and supports your permit application. We also maintain full liability insurance and respect all approach distances near your private electrical service entrance and the public distribution network operated by your local utility or Hydro One.
When we work near hydro lines, we maintain safe clearance and never contact the utility infrastructure. If your ash is directly beneath or very close to overhead lines, we coordinate with the utility or use specialized techniques to ensure no contact occurs. This protects you, our crew, and the community's power supply.
All debris is removed or chipped on site. We do not leave brush piles, stumps, or wood chips unless you request them for mulch or landscaping purposes. Your lot is returned to clean, usable condition.
When to Remove Your Ash Tree
Timing affects both safety and cost. Ash tree removal is safest and most efficient during dormancy, from late fall through late winter, when branches are firm and the ground is stable. However, if your ash is actively hazardous (large dead limbs, signs of imminent failure), we remove it immediately. We operate year-round, including emergency removals after ice storms or windstorms that damage or topple ash trees.
If you are considering emerald ash borer treatment to preserve a valuable ash, the window is late spring to early summer. This option works only if the tree is still healthy and the infestation is caught early. Once an ash shows significant crown dieback or hollow sections, removal is the only safe option.
Do not delay removal of a condemned ash. Each season of wind and ice stress weakens the tree further, increasing the risk of sudden failure and the cost of emergency removal.
Why Choose Ottawa Tree Trimming for Ash Removal
