Demolition Without a Permit in Toronto
Do not begin demolition that requires a permit until Toronto Building has issued it, and pause work if the approval status is uncertain.
Contact Toronto Building or a qualified permit professional to identify the required documents and resolve any unpermitted work.
Why the permit comes first
Ontario's Building Code Act and Toronto Municipal Code Chapter 363 govern building and demolition permits. The exact approval path depends on the structure and scope, but a contractor's availability or an owner's consent is not a substitute for an issued permit.
Permit review allows the City to assess submitted information before the building is altered or removed. It can also connect the work to required drawings, replacement-building conditions, heritage review, rental-demolition controls or other approvals. Those questions should be resolved before mobilization.
If work has already started
Stop the affected demolition and protect the area from access, weather and falling material. Do not continue in an attempt to make the site look complete. Continuing can increase safety risk and make it harder for the City and design team to understand the original condition.
Contact Toronto Building to explain the property and work. The City can investigate work carried out without a permit and may issue orders. The response depends on the facts, so do not rely on a general description of penalties or assume that applying afterward automatically authorizes completed work.
Other requirements still apply
A permit does not replace utility disconnects, designated-substance duties or contractor safety obligations. Section 30 of Ontario's OHSA requires the owner to address designated substances before the project is tendered or arranged. Ontario Regulation 278/05 applies where asbestos may be disturbed.
Rental properties, heritage properties and sites with shared structural conditions can have additional review. Public-right-of-way use for bins, hoarding or equipment may also require separate transportation approvals. Identify each authority rather than treating the demolition permit as one universal permission.
Restart only with a documented path
Once the required approvals, reports and service confirmations are in place, revise the demolition scope to match them. The site team should have access to current drawings and conditions, and any work already completed should be reflected accurately.
MetroPoint can assess demolition access and removals, but Toronto Building decides municipal permit requirements and enforcement. If there is uncertainty, ask the City before demolition. A short delay to confirm the correct path is safer than proceeding on an assumption.
Before any demolition begins
Every demolition project should begin with a scope tied to the actual property. Confirm who holds the permit, who is responsible for professional design, and which services must be disconnected or protected. The owner must address the designated-substance duties in section 30 of Ontario's Occupational Health and Safety Act before tendering or arranging the project. Where asbestos-containing material may be disturbed, Ontario Regulation 278/05 applies. These provincial duties remain relevant even when a municipal permit or property approval is already in place.
A site review should record access, occupied areas, neighbouring conditions, items to remain and the route used to remove material. The written scope can then separate demolition from electrical, plumbing, abatement, engineering, restoration and later construction work. If concealed conditions differ from the documents, the affected removal should pause until the responsible party reviews the change. This guide provides general planning information, not legal or engineering advice. Confirm current requirements with the City, the property authority and qualified project professionals.
Key takeaways
- Pause work when permit status is uncertain.
- Toronto Building decides the municipal permit path.
