Quick Answer: The cost to demolish a house in Ontario usually falls between $24,000 and $55,000 for a full GTA teardown in 2026, once permits, abatement, utility disconnections and tipping fees are counted. The structure alone runs about $5 to $10 per square foot. Asbestos, foundation removal and site access move the number most.
What is the cost to demolish a house in Ontario?
The cost to demolish a house in Ontario is the full price of taking a building down and leaving a clean lot. It covers the municipal permit, a hazardous materials survey, utility disconnections, machine work, hauling and site restoration. In the GTA, published 2026 figures put a complete teardown at $24,000 to $55,000. leedwaygroup
Leedway Group is a family-owned design-build firm in Mississauga, serving homeowners across Oakville, Burlington and the GTA since 2009. If your teardown is the first step of a rebuild, price it the way a builder would: by scope. leedwaygroup
Scope is where quotes go wrong. A structure-only price, a price with foundation removal and a site-ready price are different numbers. Two quotes for the cost to demolish a house can sit $20,000 apart simply because they cover different scopes. buildersontariobuildersontario
A low quote is usually a short scope.
How much does it cost to demolish a home in Ontario in 2026?
HomeStars’ price guide puts Ontario house demolition at $5 to $10 per square foot, against $5 to $15 across Canada. A 2,000-square-foot house works out to $10,000 to $20,000 for the structure. Abatement, foundation removal, permits and restoration come on top, which is why complete GTA teardowns cost more.
| Cost item | Typical range | Notes |
|---|---|---|
| Structure demolition and haul | $5 to $10 per sq ft | Higher for brick, concrete or tight access |
| Designated substance survey | $400 to $2,000 | Needed before contractors bid |
| Asbestos removal | $8 to $25 per sq ft | Depends on how much is found and where |
| Site grading | $0.50 to $5 per sq ft | Deep basements and wet soil cost more |
The ranges are HomeStars’ published figures; apart from the per-square-foot demolition rate, they are Canada-wide. A written quote for your address will be tighter.
Labour cost and demolition equipment
A detached house with room for an excavator, bins and trucks is quick work: one to three days on site. Attached homes need hand or selective demolition, which takes more labour per square foot. So labour cost climbs as access shrinks. A compact house on a narrow urban lot can cost more per square foot than a larger home that’s easy to reach. Demolition Contractors: Mississauga 2026 +2
Bigger jobs carry paperwork too. Under O. Reg. 213/91, the constructor files a Notice of Project with the Ministry of Labour before demolishing any building at least four metres high with a floor area of 30 square metres or more. Most two-storey houses qualify. leedwaygroup
Waste disposal
Disposal is often priced by weight, and brick, block, plaster and concrete are heavy. A modest brick house can fill more bins than its size suggests. Ask for demolition labour and disposal as separate lines so you can see which part is variable. buildersontario
It’s worth asking where the debris goes. Construction, renovation and demolition waste makes up 4 million tonnes, or 12%, of Canada’s solid waste stream, according to Environment and Climate Change Canada. Concrete, metal and wood can be recycled. canadaleedwaygroup
Demolition permit fees
Every municipality sets its own fee. Greater Sudbury publishes a $108 minimum for regular buildings, and Mississauga charges no demolition control fee for fewer than six dwelling units. leedwaygroup
The permit is rarely the expensive part. The weeks it takes are. Our guide to when you need a demolition permit in Ontario lists the documents to gather.
Which extras add the most to an Ontario demolition quote?
Asbestos adds the most to the cost to demolish a house, followed by foundation removal and site restoration. HomeStars puts abatement at $8 to $25 per square foot, which can add $5,000 to $30,000 or more. The survey isn’t optional: Ontario law requires designated substances to be identified before a contractor signs.
Asbestos removal and hazardous materials
Section 30 of the Occupational Health and Safety Act makes the owner identify designated substances and hand the list to bidders before a contract is signed. There are eleven, and asbestos and lead are among the most common. Ontario Regulation 278/05 then sets how asbestos is handled on demolition projects. leedwaygroupcanadianunderwriter
Homes built before 1990 are the ones to watch. Health Canada says fibres get into the air when building materials are broken apart during renovation and demolition, and advises hiring a professional to test first. canada
Budget a contingency until results are back, because a small finding costs a few thousand dollars and a house with several affected materials costs far more. A pre-demolition inspection settles the question early. buildersontario
Backfilling and grading
Once the foundation is out, there’s a hole. Backfilling it, compacting the fill and rough grading the lot is what separates a demolished site from one you can build on. Deep basements, wet soil and groundwater push the price up. buildersontario
Some municipalities, The Blue Mountains among them, require the lot graded after debris is cleared so it doesn’t pond or settle. Winter makes compaction harder when frost is deep, so a January teardown isn’t automatically cheaper. leedwaygroupbuildersontario
The rebuild deadline most cost guides skip
In Mississauga, a house teardown needs a Demolition Control Permit under By-law 0045-2019, and the replacement home must be substantially complete by a date at least two years after demolition begins. Tear down before your plans are ready and you carry an empty lot against a deadline. leedwaygroup
There’s a small upside. Mississauga notes that owners may qualify for a property tax reduction once a building is demolished. Still deciding whether the house should come down? Read our renovation versus rebuild comparison first. leedwaygroup
Frequently asked questions
1. How much does it cost to demolish a 1,500 square foot house in Ontario?
At HomeStars’ published Ontario range of $5 to $10 per square foot, a 1,500-square-foot house costs roughly $7,500 to $15,000 for the structure alone. Foundation removal, abatement, permits and site restoration are extra. Complete GTA teardowns run $24,000 to $55,000 in 2026, so ask what each quote leaves out. leedwaygroup
2. Do I need a demolition permit to tear down a house in Ontario?
Yes. The Building Code Act requires a permit to demolish a building, which generally means any structure larger than 10 square metres. Your municipality issues it and sets the fee. Mississauga also requires a Demolition Control Permit for dwellings, with a rebuild deadline attached. leedwaygroup
3. Is asbestos testing required before demolition in Ontario?
Yes. Ontario Regulation 278/05 requires asbestos-containing materials to be identified before any demolition that may disturb them. The Occupational Health and Safety Act also makes the owner list designated substances for bidders. Older homes can hide asbestos in floor tiles, plaster and insulation. leedwaygroup
4. What should a house demolition quote include?
A complete quote breaks the price into five lines, so two bids can be compared on the same scope:
- Scope and demolition method
- Permit fees and utility disconnections
- Hazardous material abatement
- Hauling, tipping fees and foundation removal
- Backfilling and the final grade of the lot
5. How long does it take to demolish a house in Ontario?
One to three days of machine work for a typical house, plus a day or two of cleanup. Approvals take longer: budget a few weeks for the permit and utility disconnections. Ontario One Call needs at least five business days’ notice for locates, so book early. Demolition Contractors: Mississauga 2026 +2
Conclusion
The cost to demolish a house in Ontario depends less on the excavator than on what’s inside the walls and how you need the lot left afterward. Get the hazardous materials survey done first. Then have every contractor price the same scope in writing, from permit to final grade. If a new home is the goal, settle the design before the teardown, because in Mississauga the rebuild clock starts on the first day of demolition.
