Tearing down a house isn’t just a matter of swinging a wrecking ball and calling it a day. The house demolition process in Toronto and across the GTA is a structured, highly regulated journey that involves planning, safety protocols, permits, and, yes, even conversations with the neighbours. If you’ve been wondering what to expect during house demolition, this guide will walk you through the steps so you know exactly what’s ahead.
At MAGCOR, we’re licensed, insured, and trusted across the GTA to handle every part of demolition, from demolition permits and hazardous materials removal to deconstruction and post-demolition cleanup. Our goal is to give homeowners peace of mind by managing the heavy lifting, literally and figuratively.
Key Takeaways Before We Dive In
- Demolition in Toronto is heavily regulated; permits, inspections, and approvals are crucial.
- Safety and hazardous materials, such as asbestos, can’t be ignored; proper removal is critical.
- Utilities, trees, and neighbours all play a part in planning.
- The steps in home demolition vary depending on whether it is a full demolition, selective demolition, or deconstruction.
- MAGCOR offers end-to-end service: permits, abatement, demolition, debris removal, and site grading.
Step 1: Site Walkthrough & Transparent Quote
Before the first brick comes down, MAGCOR conducts a thorough site walkthrough. This helps us understand access points, whether the foundation or basement requires special consideration, and if any materials can be salvaged. Salvage often surprises homeowners; it’s not just about tearing down, it’s about reusing what still has life.
Under Ontario regulations, a Designated Substances Survey is often required. If there’s a chance of asbestos, testing must be completed before demolition can begin. This isn’t red tape for the sake of red tape; it’s about keeping your family, the community, and workers safe.
Step 2: Permits & Required Approvals
One of the most common questions we hear is: Do I need a permit to demolish a house in Toronto? The answer is yes.
The City of Toronto requires a Demolition Permit, with or without plans for a replacement building. This involves forms like the Application to Construct or Demolish and sometimes the Infill Public Notice. As of 2025, updated fees apply.
In some neighbourhoods, Demolition Control or heritage status checks can add another layer of review. Don’t worry; MAGCOR manages all permit paperwork, so you don’t have to chase City Hall.

Step 3: Utilities, Locates & Lead Times
Safety starts with knowing what’s underground. In Ontario, you must request locates through Ontario One Call at least five business days before excavation or ground disturbance.
From there, utilities must be disconnected:
- Toronto Hydro: permanent disconnection requests need early scheduling.
- Enbridge Gas: stopping or relocating service requires coordination.
- ESA (Electrical Safety Authority): must be notified, with inspections when necessary.
These steps can take weeks, which is why MAGCOR always builds them into the project timeline.
Step 4: Tree, Noise & Neighbour Considerations
Did you know that trees are often the unsung heroes (and headaches) of demolition projects? Toronto’s Private Tree By-law protects trees with a trunk diameter of 30 cm or more. Street trees are always protected. That means tree permits and protection zones need to be in place before work begins.
Noise is another factor. In Toronto, construction noise isn’t allowed between 7:00 p.m. and 7:00 a.m., on Sundays, or on statutory holidays. MAGCOR keeps neighbours informed in advance to help maintain goodwill; it’s always better to keep the peace than have angry knocks on your door.
Step 5: Hazard Abatement & Safety Setup
Before demolition equipment arrives, hazardous materials removal takes centre stage. Ontario’s O. Reg. 278/05 outlines strict asbestos abatement requirements, and designated substances like lead or mercury must also be identified. As the property owner, you’re legally responsible for knowing what’s in your home.
Safety is equally important. Fencing, signage, and dust-control measures are set up to keep the site secure and the community safe. Think of it as building a fortress before dismantling one.

Step 6: Choose the Right Method: Full Demo, Selective, or Deconstruction
Not every project calls for the same approach:
- Full demolition: The fastest and most cost-efficient.
- Selective demolition: Removing only part of the structure.
- Deconstruction vs demolition: Deconstruction salvages materials like wood, brick, or fixtures, reducing landfill waste.
Cities in the GTA are increasingly encouraging the salvage of materials. Many homeowners also appreciate the idea of recycling and reducing their environmental footprint; it’s not just good for the planet, but also for their conscience.
Step 7: Demo Day: What You’ll Actually See
This is the part most people picture when they think “demolition.” On demo day, crews typically start with a soft strip, removing interior elements like drywall and wiring. From there, structural dismantling begins, with dust-control systems running and debris hauled off daily.
MAGCOR utilizes specialized equipment and adheres to a rigorous demolition safety checklist. If you’re watching from the sidelines, expect a surprisingly organized process rather than Hollywood-style chaos.
Step 8: Waste, Recycling & Site Cleanup
Once the house is down, attention turns to sorting and removing debris. Metal, concrete, and wood are separated on site, aligning with GTA diversion practices. Dumpster rental for demolition is coordinated in advance, keeping the site orderly and efficient.
The post-demolition cleanup includes grading, backfilling, and compaction if a basement was removed. When MAGCOR hands the site back, it’s “site-ready”; a clean slate for whatever comes next.
Step 9: Timelines & Cost Factors
So, how long does it all take? A typical single-family home in Toronto might look like this:
- Permits and utility disconnects: a few weeks.
- Demolition: 1–3 days.
- Post-demolition cleanup: 1–2 days.
Costs vary depending on size, access, the need for hazardous materials removal, and disposal requirements. Deconstruction often takes longer and costs more, but saves more in materials. For detailed cost insights, check out How Much Does It Cost to Demolish a House?.
Step 10: Homeowner Checklist
Here’s a handy snapshot before demolition begins:
✔ Permits submitted
✔ Utilities scheduled
✔ Ontario One Call locates booked
✔ Tree permits arranged
✔ Neighbour notice given
✔ Salvage list created
✔ Temporary accommodation during demolition planned
Speaking of which, if you’re staying nearby, remember that living in a house being demolished isn’t an option. Temporary accommodation during demolition is a must.
