You’ve got a dead oak in the backyard or a silver maple that’s been slowly lifting your driveway. Seems straightforward — call a crew and take it down. But in most Ontario municipalities, removing a tree on your own property isn’t as simple as booking the job. You may need a permit first.
Here’s what GTA homeowners need to know before any tree comes down.
Why Tree Removal Permits Exist
Ontario municipalities protect trees — especially mature ones — through local tree bylaws. The goal is to preserve the urban canopy, which reduces stormwater runoff, lowers summer temperatures, and supports local wildlife.
Under these bylaws, cutting down a tree above a certain size without prior approval can result in fines, stop-work orders, or requirements to replant. In some cases, penalties run into the thousands of dollars per tree.
Does Your City Require a Permit?
Rules vary by municipality across the GTA. Here’s a general breakdown:
- Toronto — A permit is required to remove any tree with a trunk diameter of 30 cm or more (measured at 1.4 m above the ground). The City’s Private Tree Bylaw covers trees on private property.
- Richmond Hill — Trees with a diameter of 15 cm or more on private property are protected. Removal requires a permit and, in some cases, a replacement planting commitment.
- Markham, Vaughan, and Mississauga — Each has its own protected tree thresholds and application processes, typically ranging from 10 to 20 cm trunk diameter.
If your tree is near a ravine, woodlot, or designated natural heritage area, the requirements become even more strict regardless of which city you’re in.
When You Might Not Need a Permit
There are some common exceptions, though these still vary by municipality:
- The tree is clearly dead, diseased, or poses an immediate safety hazard
- The trunk diameter falls below the local threshold
- The tree is a nuisance species explicitly excluded from the bylaw (such as Manitoba maple in some jurisdictions)
Even in these cases, documenting the condition of the tree before removal — with photos and ideally an arborist report — is strongly recommended. It protects you if questions arise later.
What the Permit Application Usually Involves
Most GTA municipalities require the following to process a tree removal permit:
- A completed application form (available through your city’s website or permit office)
- A site plan or property survey showing the location of the tree
- An arborist report from a certified arborist assessing the tree’s condition and the reason for removal
- A replanting or compensation plan, especially if the tree is large or healthy
The arborist report is often the most critical piece. It needs to be written by an ISA-certified arborist and should clearly document species, diameter, condition, and the rationale for removal. Our team at Five Star Tree Care provides professional arborist reports that meet municipal standards across the GTA.
How Long Does It Take?
Processing times vary by city and workload, but expect:
- Toronto — Typically 10 to 20 business days
- Richmond Hill / York Region — Often 2 to 4 weeks
- Urgent or safety-related cases — Some municipalities allow expedited review when a tree poses an imminent hazard
Plan ahead. If you’re working around a construction timeline or need the tree removed before a specific season, factor in permit processing time well in advance. Our construction tree services team regularly coordinates these timelines with developers and homeowners.
What Happens If You Skip the Permit?
Removing a protected tree without a permit can result in:
- Fines ranging from $500 to $100,000 depending on the municipality and tree size
- Mandatory replacement planting (often at a ratio of 2:1 or higher)
- Delays to construction or development projects
- Legal disputes if the removal affects a shared property line
It’s not worth the risk, especially when getting proper approval is straightforward with the right help.
