Tree Canopy Conservation Program

Cable/brace/prop 

• Different approaches used to provide physical support to trees to allow reaction wood to develop and prevent failure. 

Pruning 

• Pruning of dead, cracked, or broken limbs.
• Pruning of branches to improve tree structure to ensure adequate growth in future years.
• Pruning completed in a way that mimics natural decline in veteran trees. In some instances, this type of pruning may be considered an injury to a tree but is a useful method to retain veteran trees for longer when they are in a late stage of life. 

Integrated pest management

• Integrated pest management is a method that combines both preventative and control measures for managing pests to a tolerable threshold. 

• the arborist's information
• what services or materials are being supplied
• to whom (i.e., you), the cost, and the date the work was quoted. 

The arborist's assessment, quote and other supporting documentation should not be more than six months old. 

• We will review your application.
• We will arrange a site visit.
• If your application is approved, you may schedule the work.
• Once work is completed, please submit the paid invoice.
• You will receive a cheque in the mail within four weeks of us receiving a copy of the paid invoice

That’s it! If City staff need anything else, they will contact you. Thank you for helping grow and preserve our Urban Forest! 

You received an Offer of Award in 2026, now what?

Participants who received an Offer of Award in 2026 must schedule their arborist to complete and bill that work in 2026.

In order to be able to claim the Award, you need to submit proof-of-payment for the services listed in that Offer letter to trees@london.ca. The due date for getting that paperwork to us is approaching. To be eligible to claim your award, please submit proof-of-payment by the date you were given. If you need to discuss this date, please be in touch. 

Once you submit this documentation, an inspector will conduct a follow-up visit to verify that work has been done as per the program. After work has been verified, you will be issued a cheque to be delivered via Canada Post.

If you no longer wish to participate in the program, please send us a quick note so that we may update our files. If you do not reply before your due date, we understand that you do not wish to participate in the program, and your Offer of Award will be revoked.

Due to the concern of Oak Wilt, any work on oak trees will be deferred to the months of November to March.

Who is eligible for the program? 

If you are a resident or property owner in London with a tree 40 cm or greater in diameter, you may be eligible for the Tree Canopy Conservation Program. Furthermore, all proposed work must be completed by a qualified arborist as per the City of London’s Tree Protection By-law.  

How is ‘qualified arborist' defined for this program? 

Applicants must hire a qualified arborist as per the City of London’s Tree Protection By-law to complete all eligible work. The Tree Protection By-law defines an “Arborist” as: 

• Arborist qualified by the Ontario Ministry of Training, Colleges and Universities
• Certified Arborist with the International Society of Arboriculture
• Consulting Arborist registered with the American Society of Consulting Arborists
• Registered Professional Forester

Please note that a utility arborist may not be considered a qualified arborist for this program. The City will not award funding if the proposed work is not completed by a qualified arborist.

What is Diameter at Breast Height (DBH)?

The measurement of the diameter of the tree taken at 1.4 meters above natural ground level. To calculate diameter, divide the circumference (measure all the way around the tree using a flexible measuring tape) by Pi (3.14).  

What type of work is eligible? 

The goal of this program is “to defer the removal of the largest trees to the latest possible date while allowing for successional planting to catch up”. This can include types of pruning, Integrated Pest Management (IPM) and cabling/bracing practices. When in doubt, please ask City staff to confirm whether the proposed work for your tree(s) might be supported by the Tree Canopy Conservation Program.   

There is an eligible tree on my property. How do I apply? 

Applications can be submitted from the online application form located at the bottom of this page.  If you require a paper copy of this application, please contact us at 519-661-5783 or email trees@london.ca.

Applications for the Tree Canopy Conservation Program will be considered strictly on a first-come first-served basis until all available funds have been spent.  

You will be required to submit a quote or contract to support your request, which will be used to determine how much funding you may receive through the program. 

City staff may visit your property to verify your application. City staff may request photographs of the tree to avoid a site visit or in-person meeting.

I can’t afford to pay for the entire job upfront. Can you pay direct to my contractor? 

No, the Tree Canopy Conservation Program is strictly for property owners and will not be paid to contractors. Your contract is between you and your contractor. The City will ensure any award is processed as quickly as possible.   

Can I apply for money to pay for work already done? 

No. Retrospective applications are not eligible and will not be considered for the program. You should not commence any work before assistance has been approved by City staff. 

Can I use the Tree Canopy Conservation Program to pay for work required by an Order of the City? 

No. If you have received an Order from the City to abate a safety concern under the Property Standards By-law, or an Order made for any other reason, it is not eligible.  

Will everyone getting assistance from the program receive the same amount? 

No. The City will determine how much assistance to offer subject to availability and on a case-by-case basis. The program reimburses eligible costs up to $1,000 per tree, to a maximum of $5,000 per property. Most awards will be less than $1000 to ensure that the City assists as many property owners as possible. 

What is proof-of-payment?

Offers of Award are issued based on an Arborist’s Estimate for specific tree care services. Proof-of-payment shows that you have paid in full for those services. This can look like a receipt from your tree care company or an Invoice marked PAID showing a zero balance. Other forms of proof may be accepted; please contact trees@london.ca to find out if the document you wish to submit meets the requirement.   

PLEASE NOTE: Proof-of-Payment may be dated in 2027. Invoices sent by arborists listing work completed are to be dated in 2026.
