Tree removal regulations and permit processes in Ottawa serve to protect the city’s urban canopy and ensure safety and compliance during property-altering work. Under the Tree Protection By‑Law No. 2020‑340, many trees on private and public land require official approval before they can be cut down—especially those meeting specific size and location criteria.
Residents wanting to remove a tree in Ottawa should review the criteria for a tree permit, submit a Tree Information Report if required, and post the approved permit on-site ahead of removal. Properties in the urban zone often require a permit for trees with a trunk diameter of 30 cm or more, measured at 1.3 m above ground.
Do You Need a Tree Removal Permit in Ottawa?
Yes, obtaining a tree removal permit in Ottawa is often mandatory to protect the city’s urban canopy, maintain biodiversity, and ensure public safety. The City of Ottawa regulates tree removal through Tree Protection By-Law No. 2020-340, which applies to private and public properties. Homeowners, developers, or contractors must adhere to these regulations to avoid fines and legal issues, especially when removing large, mature, or protected trees. Permits are required based on tree size, location, and condition, and certain exceptions exist for emergency or hazardous tree removals.
Key considerations for tree removal permits in Ottawa include:
- Diameter Thresholds: Trees with a trunk diameter of 30 cm (12 inches) or more at 1.3 m (4.3 feet) above ground require a permit.
- Protected Species: Some native or rare tree species may require additional approvals for removal.
- Property Type: Permits are required for trees on residential, commercial, municipal, or conservation land.
- Exemptions: Emergency removals due to safety hazards or dead/dying trees can sometimes proceed without a prior permit, but usually require documentation afterward.
- Application Requirements: Submissions typically include a Tree Permit Application, site plan, photos, and sometimes an arborist report confirming the tree’s condition.
- Penalties: Removing a tree without a permit can lead to fines, mandatory replacement, or restoration requirements, which can be costly.
- Professional Consultation: Hiring a certified arborist ensures compliance, proper assessment of tree health, and guidance on legal removal procedures.
Following these rules not only ensures legal compliance but also supports sustainable tree management in Ottawa, helping protect neighborhoods, maintain property value, and contribute to the city’s environmental goals.
How Does One Get a Tree Removal Permit in Ottawa?
Acquiring a tree removal permit in Ottawa involves a structured process designed to balance property needs with urban forest conservation. Property owners must submit a detailed application to the City of Ottawa’s Urban Forestry Services, including the tree’s species, size, location, and reason for removal. Justifications often include safety hazards, disease, or interference with planned construction.
For certain protected or large trees, the city may require a professional arborist’s assessment to confirm the tree’s condition and the necessity of removal, ensuring that every decision supports environmental sustainability and public safety.
After applying, city officials may conduct an on-site inspection to evaluate the tree’s health, potential risks, and impact on surrounding properties. If the removal is approved, the permit often includes conditions, such as replanting requirements or specific methods for safely cutting and disposing of the tree. Strict adherence to these regulations is crucial, as unauthorized removal can lead to fines or legal consequences.
Partnering with a certified arborist or licensed tree service ensures that the work is completed efficiently, safely, and in full compliance with Ottawa’s municipal rules, protecting both property and the city’s urban canopy.

Exceptions to Ottawa Tree Permit Requirements
Here are the exceptions to tree permit requirements in Ottawa, based on current tree-protection laws and official resources:
- Removal of trees that pose an immediate threat to public health and safety (for example, dead or hazardous trees leaning toward structures) does not require a permit.
- Trees located within private courtyards, solariums, rooftop gardens, or similar confined spaces are exempt from permit requirements under certain conditions.
- Trees on properties used as farms, orchards, nurseries, or on golf courses or cemeteries may be exempt from needing a permit, depending on the context and local zoning.
These exemptions help property owners understand when they may safely remove a tree without requiring a full permit, but verifying your specific situation through the city’s decision tool or consulting an arborist is always advised.
Types of Tree Removal Permits in Ottawa
Tree removal in Ottawa is regulated under the City of Ottawa Tree Protection By-law (No. 2020-340), which ensures that the city’s valuable urban canopy is preserved. Depending on your property type, tree size, and removal reason, different permits may be required. Understanding these permit types helps homeowners, developers, and businesses stay compliant while protecting the environment.
1. Distinctive Tree Permit
A Distinctive Tree Permit is required for trees located on private property within the urban boundary that have a trunk diameter of 30 cm or more, measured at breast height (1.3 meters from the ground). This permit ensures that significant trees contributing to Ottawa’s green cover aren’t removed without valid justification.
- Applies to private lots less than one hectare in size.
- Needed for trees ≥ 30 cm diameter at breast height (DBH).
- Common for homeowners planning landscaping, construction, or yard expansion.
Ottawa property owners should always verify if their trees meet the “distinctive” threshold before removal to avoid fines and delays.
2. Urban Tree Conservation Permit
The Urban Tree Conservation (UTC) Permit applies to properties one hectare or larger within the urban boundary. It’s also required for tree removal in preparation for development or subdivision work, even on smaller lots. This permit ensures that large-scale removals are environmentally balanced through replanting or mitigation requirements.
- Required for major developments, subdivisions, or large lots.
- Must include a Tree Conservation Report prepared by a certified arborist.
- Focuses on sustainable management and protection of mature trees.
Developers in Ottawa should consult a certified arborist to prepare proper documentation before applying for a UTC permit to streamline approval.
3. Tree Permit for City-Owned or Public Property
Any trees located on city-owned land, road allowances, or public spaces require a City Tree Permit before removal. This includes trees near sidewalks, parks, or boulevards that may interfere with infrastructure or pose safety hazards.
- Managed directly by the City’s Forestry Services Department.
- Removal requests are reviewed based on public safety, tree health, and impact on nearby properties.
- Replacement or compensation planting is often required after removal.
Always confirm ownership boundaries before removal — trees growing near sidewalks or property lines might belong to the City of Ottawa, not the homeowner.
4. Emergency Tree Removal Authorization
For hazardous trees that pose immediate risks to safety or property, the City allows emergency removal without prior permit approval. However, the property owner must provide evidence (photos or arborist reports) and notify the City after removal.
- Applies to trees damaged by storms, lightning, or disease.
- Must document the emergency condition before cutting.
- A follow-up inspection or replacement plan may still be required.
In urgent cases, homeowners should contact Ottawa’s 3-1-1 service or a licensed arborist to document the hazard properly before proceeding.
The Consequences for Not Obtaining a Permit for Ottawa Tree Removal
Removing a tree in Ottawa without the required permit can result in severe penalties under the Tree Protection By-law (No. 2020-340). Property owners or contractors may face fines ranging from $500 to $100,000 per tree, depending on factors like trunk size, species, and location. The City of Ottawa also has the authority to issue stop-work orders, demand tree replacement, or require contributions to the Tree Compensation Fund. These actions can significantly delay construction or landscaping projects and lead to long-term financial setbacks.
Unauthorized tree removal also damages Ottawa’s commitment to urban canopy preservation, which affects neighborhood aesthetics and environmental health. In addition to financial penalties, violators may experience legal action or difficulty obtaining future permits if non-compliance is recorded. Proper documentation and professional guidance help homeowners avoid these costly mistakes and maintain a good standing with city regulations.
Tips to Stay Compliant and Avoid Penalties:
- Verify whether your tree qualifies for a Distinctive Tree Permit before any removal.
- Consult a certified arborist for accurate tree assessment and permit assistance.
- Submit your application through the City of Ottawa’s Forestry Services portal before scheduling work.
- Keep a copy of your approved permit on-site during tree removal.
- Reconfirm compliance if your property lies within a protected area or heritage district.
Following these steps ensures you meet city requirements, protect your property’s value, and contribute to Ottawa’s sustainable tree management efforts.
