Stump Removal & Grinding Cost in Toronto & GTA: 2026 Guide

After a tree comes down, the stump is the part that ruins the lawn, kills the lawnmower blade, and gets in the way of every future landscaping plan. In Toronto and the GTA in 2026, stump grinding runs $150 to $700 per stump depending on size and access. Full mechanical removal with the root ball is more expensive at $300 to $1,500 per stump. We are OCM Excavation & Construction. Call 416-317-3090 for a quote that includes hauling and cleanup. We work across Toronto, Vaughan, Markham, Mississauga, Oakville, and the rest of the GTA.

Stump Grinding vs. Stump Removal: Which Do You Actually Need

The first decision is grinding or removal. They cost different amounts and leave different results.

Stump Grinding

A rotary cutting wheel grinds the stump 6 to 10 inches below grade. The roots stay in the ground and decay over 5 to 10 years. Cheaper, faster, less mess. Fine for replanting grass, garden beds, or laying interlock over the spot.

Stump Removal (Excavation)

A mini-excavator pulls the entire root ball out of the ground. Leaves a 4 to 8 foot wide crater that needs backfill. Required if you are pouring a foundation, building a pool, installing a driveway, or planting a new tree close to the same spot.

What Stump Work Actually Costs Across the GTA in 2026

• Small stump grinding (under 12 inches diameter): $150 to $250.
• Medium stump grinding (12 to 24 inches): $250 to $400.
• Large stump grinding (24 to 36 inches): $400 to $700.
• Extra large or extra deep (oak, maple, over 36 inches): $700 to $1,200.
• Mini-excavator full removal of root ball (small stump): $300 to $600.
• Full removal of medium to large stump with hauling: $800 to $1,500.
• Multi-stump volume discount: First stump full price, each additional stump $100 to $250 less.
• Backfill with topsoil and reseed: $100 to $400 per stump location.
• Hauling chips off site: $100 to $300 depending on volume.

Mobilization is the main fixed cost on any stump job. The grinder is on the trailer either way, so once we are on site, the per-stump cost drops fast. If you have 3 or 4 stumps, get them done together.

What Drives the Price

Stump Diameter

Measured at grade, not at the original DBH. A 30-inch stump takes 3 to 4 times the grinding time of a 12-inch stump. Diameter is the single biggest variable.

Wood Species

Hardwoods like oak, sugar maple, and ironwood are dense and grind slowly. Softwoods like silver maple, willow, and pine grind fast. Same diameter oak versus willow can differ $100 to $200 in cost.

Root Spread

Surface roots radiating out from the stump need to be ground too if you are sodding the area. Visible roots beyond the stump add per-linear-foot grinding charges, typically $5 to $15 per foot of root.

Access

A self-propelled grinder fits through a 36-inch gate. Anything narrower means a smaller machine, hand work, or no go. Old Toronto neighborhoods like Roncesvalles, Cabbagetown, and Greektown often have 28 to 32 inch gates that require special equipment. Add $150 to $400 per stump for tight-access lots.

Soil Conditions

Rocky soil eats grinder teeth. Sandy soil grinds clean. Clay (most of the GTA) is straightforward. If your yard is full of buried rubble or old foundation stone (common in pre-war Toronto), expect a small surcharge for tooth wear.

Toronto Tree By-law: Read This Before You Touch a Live Tree

Stump grinding a dead-and-removed stump is unregulated. But if the tree is still standing or recently cut, the by-law applies.

• Toronto: Municipal Code Chapter 813 protects every private-property tree 30 cm DBH or larger. Permit required before removal. Replacement planting or cash-in-lieu to the Tree Planting Fund.
• Vaughan: By-law 177-2025 sets the threshold at 20 cm DBH. Consolidated 2025 version.
• Oakville: Private Tree By-law at 15 cm DBH, one of the strictest in the GTA.
• Markham, Richmond Hill, Mississauga, Brampton, Aurora, Newmarket, King City: All have their own private tree protection by-laws. Confirm with the municipality before cutting.

Unpermitted removal of a protected tree in Toronto can hit you with fines from $500 to $100,000 per tree under Chapter 813. Confirm current Chapter 813 fees and process with Toronto Urban Forestry (call 311) before scheduling any tree or stump work. The permit fee structure changes; secondary sources disagree on the exact number; only the city can confirm what your specific tree costs.

Our Process

1. Quote. Phone quote if you can send photos with a tape measure across the stump. Otherwise site visit.
2. Ontario One Call locates. Mandatory if grinding goes below 30 cm or near utilities.
3. Setup. Tarp around the work area to contain chips. Move patio furniture.
4. Grind. 30 minutes to 2 hours per stump depending on size.
5. Cleanup. Chips left in hole by default, hauled off if requested.
6. Optional backfill and reseed. Topsoil and grass seed if you want the spot back to lawn.

When You Need Full Excavation, Not Grinding

Four scenarios where grinding alone is not enough:

• Building a pool over the spot. Pool excavation hits 4 to 8 feet deep. Root balls have to come out. See our pool excavation cost guide.
• Pouring a foundation. Roots under a footing rot, settle, and crack the concrete. Full root removal required.
• New driveway or interlock. Decaying roots create voids under the base. See our driveway excavation cost guide.
• Replanting a new tree. A new tree planted in old wood-chip fill struggles. Pull the old root ball, backfill with clean soil.

Frequently Asked Questions

How much does stump grinding cost in Toronto?

Stump grinding in Toronto and the GTA in 2026 ranges $150 to $700 per stump. Small stumps under 12 inches across run $150 to $250. Medium stumps from 12 to 24 inches run $250 to $400. Large stumps over 24 inches cost $400 to $700 or more. Multi-stump discounts are standard.

What is the difference between stump grinding and stump removal?

Grinding chews the stump down to 6 to 10 inches below grade using a rotary cutter. Roots stay in the ground and decay over years. Full removal excavates the entire root ball with a machine, leaving a clean hole. Grinding is cheaper and faster. Removal is required if you are building a foundation, pool, or driveway over the spot.

Do I need a permit to grind a stump in Toronto?

Grinding the stump of an already-removed tree typically does not require a permit. However, if the tree itself is still standing and is 30 cm DBH or larger on private Toronto property, you need a permit under the Toronto Private Tree By-law (Chapter 813) before any removal work, including the eventual stump grind.

What are the Toronto tree by-law rules?

Toronto Municipal Code Chapter 813 protects private-property trees 30 cm DBH or larger. Vaughan By-law 177-2025 sets the threshold at 20 cm DBH. Oakville is tighter at 15 cm DBH. Removing a protected tree without a permit can carry fines from $500 to $100,000 per tree. Confirm tree status with the city before any work.

Will the wood chips be left in the hole?

By default, yes. Grinding produces a pile of mulch-sized wood chips equal to the volume of the stump. Most quotes leave the chips on site at no extra cost (great for mulching beds). Backfilling with topsoil and reseeding is a separate line item, usually $100 to $400 per stump location.

How deep does the grinder go?

Standard grinding takes the stump 6 to 10 inches below grade. That is deep enough for new sod, garden beds, or interlock. If you are pouring concrete or a foundation over the spot, ask for an extra-deep grind to 18 to 24 inches or full root-ball excavation. Extra depth adds $100 to $300 per stump.

Can you grind stumps in winter in Toronto?

Yes, but frozen ground slows the work and the chips are harder to clean up under snow. Most homeowners book stump grinding April through November. Winter rates often run 10% to 20% higher due to slower production.

What about big-tree stumps in tight backyards?

Tight access is the same problem as any GTA backyard job. We use a track-mounted self-propelled grinder that fits through a 36-inch gate. For yards with no rear access, we hand-walk smaller equipment. Tight-access premium is $150 to $400 per stump on top of base pricing.
