Quick Answer: Demolition costs in Ontario run about $10,000 to $35,000 for a house in Simcoe County and $18,000 to $55,000 or more in the GTA, based on published 2026 contractor pricing. Foundation removal, asbestos abatement, permits and 13% HST are often priced separately, so a complete teardown budget can land well above those numbers.
What are demolition costs in Ontario?
Demolition costs in Ontario are everything you pay to legally remove a building and leave a clear, buildable lot. The bill covers the teardown itself plus permits, hazardous material surveys, utility disconnects, hauling and landfill tipping fees. Most quotes price the house by size and construction type, then list site work as separate line items.
At Leedway Group, we build custom homes across Mississauga, Oakville, Burlington and the GTA, and on an infill lot the first line of the budget is the old house coming down.
The machine work takes days. Permits and asbestos work can take weeks, and they carry more of the budget risk.
How much does it cost to demolish a house in Ontario?
A full house demolition in Ontario costs roughly $10,000 to $35,000 in Simcoe County and $18,000 to $55,000 or more in the GTA, per 2026 pricing from local demolition contractors. One Simcoe County contractor prices teardowns at $8 to $20 per square foot all-in. Brick cladding and a poured concrete basement push any job toward the top.
House demolition prices by home size
These 2026 ranges show how demolition costs in Ontario shift between two markets, each taken from a local demolition firm’s price guide. Both cover the structure and hauling; size bands are approximate.
| Home type | GTA | Simcoe County |
|---|---|---|
| Small bungalow (under 1,200 sq ft) | $18,000 to $28,000 | $10,000 to $20,000 |
| Mid-size detached (1,200 to 2,200 sq ft) | $24,000 to $38,000 | $12,000 to $30,000 |
| Large detached (2,200+ sq ft) | $32,000 to $55,000+ | $18,000 to $35,000+ |
The cost to bulldoze a house climbs fast once the basement comes out too. A GTA contractor’s 2026 price list puts foundation removal at $6,500 to $18,000 extra for a full poured concrete basement, and backfilling the hole adds $4,500 to $11,000.
Rebuilding? Skip the backfill if you can. Filling a hole your new foundation crew will dig out again is money spent twice.
Waste disposal and tipping fees
Transfer stations charge by the tonne, so weight drives the disposal bill. Mixed construction debris costs about $95 to $165 per tonne at GTA sites, while separated concrete runs $30 to $65. A brick-clad house can generate 60 to 110 tonnes. A wood-frame bungalow produces roughly half that.
A Vaughan owner budgeted 40 tonnes for a brick-veneer Tudor and needed 92, which added $9,000 in disposal, according to a GTA excavation firm’s 2026 cost guide.
Few cost guides mention this: Ontario’s waste audit and source separation rules only cover demolition projects of 2,000 square metres or more, per the provincial source separation guide. A 2,500-square-foot house is about 232 square metres. Sorting concrete and metal still cuts waste disposal costs, and on-site waste separation keeps recyclables out of landfill.
Demolition equipment and site access
Most teardowns run on an excavator with a thumb attachment, plus a hydraulic breaker once the crew reaches concrete. A Toronto rental company lists mid-size excavators at $450 to $700 a day and heavy-duty machines at $900 to $1,300, rates contractors build into your quote.
Access decides which demolition equipment fits.
A 30-foot Toronto lot with sidewalk-only access forces smaller machines that can double the job time. Parking bins or equipment on the road also means a street occupation permit, which Toronto prices at $73.89 plus HST per day outside a construction hub.
What hidden fees raise the price to tear down a house in Ontario?
Asbestos abatement, foundation removal, utility disconnects and 13% HST are the add-ons that commonly push demolition costs in Ontario past the first quote. In the GTA, abatement alone runs $3,500 to $22,000, and utility disconnects cost $1,800 to $5,500 combined. Permit fees are smaller, usually $350 to $2,500, but approvals can add weeks.
Permits and heritage rules
Your municipal building department issues demolition permits under Ontario’s Building Code Act. Two situations slow things down. In a demolition control area, municipal council itself must issue the permit for a residential demolition. Heritage status adds another layer: designated properties may need a separate heritage approval, and non-designated houses on a municipal heritage register require 60 days’ notice to council, according to Ontario’s building permit guide.
The permit fee is a small part of the price to tear down a house. The penalty for skipping it isn’t: an individual can be fined up to $50,000 for a first offence, and up to $100,000 for later ones.
Asbestos surveys belong before the quotes
Asbestos can add more to demolition costs in Ontario than the teardown itself. Under O. Reg. 278/05, the owner must commission an asbestos report on materials the work will disturb before requesting tenders, then share it with anyone bidding. The province’s asbestos regulation guide says the point is to get those costs into the bids.
That rule doubles as a budgeting tool: bids built on the same designated substance survey are actually comparable. A survey costs about $850 to $2,400 in the GTA.
A GTA excavation firm reports an Etobicoke case where a low-bid crew skipped the survey and disturbed asbestos. After a Ministry of Labour stop-work order, a job quoted at $19,000 ended with $48,000 in emergency abatement plus fines.
Taxes you pay and a refund you can claim
Ask whether each quote includes HST, because some don’t. Ontario’s rate is 13%, per the Canada Revenue Agency’s GST/HST rate table, which adds $4,550 to a $35,000 teardown. Our budgeting and pre-construction planning guides show where tax lines like this belong in a rebuild budget.
Now the good news. Section 357 of Ontario’s Municipal Act, 2001 lets a municipality reduce or refund property taxes when a building is razed by demolition. Applications are due by the last day of February of the following year. Toronto asks for the demolition permit and a signed contractor letter showing start and end dates, so request that letter before the crew leaves.
On a lot that sits empty through design and permitting, the refund can offset part of the cost of home demolition.
Frequently asked questions
1. Do you need a permit to demolish a house in Ontario, and what does it cost in Toronto?
Yes. Every house demolition in Ontario needs a municipal permit, and fees vary by city. Toronto’s residential demolition permit page lists a 2026 service index of $0.18 per square metre, plus $1,030.99 when an environmental review applies. Toronto also requires a municipal road damage deposit with the application.
2. How long does a house demolition in Ontario take from permit application to cleared lot?
Most GTA teardowns take 8 to 14 weeks overall, based on 2026 contractor timelines:
- Permits take 3 to 8 weeks, depending on the city.
- Utility disconnects take 1 to 3 weeks.
- Asbestos abatement takes 3 to 10 days.
- Machine demolition through rough grading takes 6 to 12 working days.
3. Is it cheaper to demolish and rebuild, or to renovate an older house in Ontario?
A GTA teardown alone costs $18,000 to $55,000 before construction starts. As our renovation vs. rebuild guide explains, renovating can be more cost-effective when the structure is sound. Rebuilding makes more sense when the foundation needs major repair or the renovation budget approaches the cost of a new home.
4. Can salvaging brick and lumber before the teardown lower demolition costs in Ontario?
Salvage can trim $1,500 to $8,000 from a typical Toronto teardown, per 2026 GTA contractor figures. Brick, structural lumber, hardwood flooring and copper plumbing can be salvaged or diverted, and brick alone can cut $1,500 to $5,000. The trade-off is time, since hand stripping adds labour days before the excavator arrives.
5. How much does it cost to demolish a detached garage in Ontario, and do you need a permit?
A detached garage costs about $3,000 to $9,000 to demolish in Simcoe County. In the GTA, expect $4,500 to $14,000 with hauling, plus $1,200 to $3,500 if a concrete slab has to come out. Permit rules vary; the Town of LaSalle, for one, requires a demolition permit for any structure over 107 square feet.
Conclusion
Demolition costs in Ontario depend less on the machine work than on everything around it. Treat published house demolition prices as a starting point. Before you ask for quotes, get a designated substance survey, and make every bidder list foundation removal, backfill, disposal and HST in writing.
If the teardown is the first step toward a new home, our custom home and design-build services keep design and permits under the same contract as construction. Whoever you hire, compare scopes, not totals.
