Two frameworks, depending on your project
Hamilton is the most layered of the cities I work in. Which rules apply depends on whether you’re doing a planning application, and on where the property is.
Development. Site plans, subdivisions, condominiums, consents and Niagara Escarpment permits follow the City’s Tree Protection Guidelines. It usually starts with a General Vegetation Inventory, and the City won’t begin its review until that and its fee are in. That puts arborist work on the critical path. Before grading, servicing or a building permit, a Verification of Tree Protection Letter confirms the protection is in.
Private trees outside development. Inside the urban area, the Urban Woodland By-law protects woodlands and, in mapped areas, individual trees 20 cm and up. Ancaster still has its own heritage tree bylaw, and Dundas and Stoney Creek have bylaws for specific lands. A single private tree bylaw for trees over 45 cm across the urban area was consulted on in 2026 but hasn’t been adopted. I’ll update this page when it is.
Street trees. Trees on City property are protected at any size, and development affecting them needs its own management plan, with non-invasive digging such as AirSpade near the roots.
What triggers a report in Hamilton?
- Consents and infill. Severances fall under the Tree Protection Guidelines, often with a protection plan as a condition of approval.
- Site plans and subdivisions, starting with the General Vegetation Inventory.
- Work near street trees, which needs a tree management plan.
- Removals in Ancaster, Dundas or Stoney Creek, or in mapped woodland areas.
How I can help
- General Vegetation Inventories and Tree Protection Plans to City standards
- Verification of Tree Protection Letters and construction monitoring
- Tree management plans for street trees, and AirSpade work inside driplines
- Private tree assessments in Ancaster, Dundas, Stoney Creek and the woodland areas
- Advice before an application goes in, while drawings can still change
I’m based in Hamilton and work regularly with its Planning and Forestry staff, including in Ancaster, Dundas, Westdale, Stoney Creek, Waterdown and Flamborough. For most infill and consent applications, a GVI takes five to seven business days from the site visit. Full plans for larger sites typically take seven to fourteen.

Common questions
Do I need an arborist before submitting a planning application in Hamilton?
Usually. For site plans, subdivisions, condominiums and consents, staff decide at formal consultation whether a General Vegetation Inventory or a full Tree Protection Plan is needed. Where a GVI is required, the City won’t start its review until it’s in. Doing it before drawings are final avoids redesigns.
What is a General Vegetation Inventory?
The first step: a site-wide overview of the vegetation that identifies what is worth keeping and whether a detailed Tree Protection Plan is needed. The plan, if needed, tags and assesses every tree 10 cm and larger and sets out how they will be protected.
What are Hamilton’s private tree rules if I am not doing a planning application?
It depends where the property is. Inside the urban area, mapped areas protect individual trees 20 cm and up, and woodlands are protected too. Ancaster protects heritage trees 45 cm and up. A single bylaw for the whole urban area has been proposed but not adopted.
How much does a GVI or Tree Protection Plan cost in Hamilton?
It depends on the size of the site, the vegetation and the scope of the application. I give a fixed quote after a short, free conversation about what you are working on.
