What Happens If I Remove a Wall Without a Permit in Ontario?
Updated October 2026 by the Puzzledesign team. Written for homeowners in Toronto and across Ontario.
Quick answer: what happens if I remove a wall without a permit? In Ontario, your municipality can issue a stop work order and an order to comply building permit notice, charge a work without a permit fee (in Toronto, an extra 50 percent of the permit fees), require you to apply for a permit after the fact, and prosecute you under the Building Code Act, 1992.
The wall removal without permit fine for an individual can reach $50,000 for a first offence. Removing a load bearing wall without a permit adds the risk of sagging floors, cracking and even collapse, and unpermitted wall removal can complicate insurance claims and the sale of your home.
Whether a simple non load bearing partition needs a permit depends on your municipality and on what is inside the wall, so confirm before any demolition starts.
You are planning an open concept main floor, and the wall between the rooms looks like an easy job. A contractor says a permit is not really necessary. It is a common story, and it is where the trouble starts.
This guide explains what happens if I remove a wall without a permit, how unpermitted wall removal is handled in Ontario, what the fines and fees really are, and how to fix the situation when the wall is already gone.
It also answers a question buyers and sellers ask often: can you sell a house with unpermitted work? The legal references come from the Building Code Act, 1992 and from City of Toronto guidance, and we point out where rules differ by municipality.

What Happens If I Remove a Wall Without a Permit in Toronto?
So, what happens if I remove a wall without a permit once the city finds out? Here is the sequence most Ontario homeowners experience. Not every step happens in every case, but every one of them is possible, and some arrive together.
Why Ontario Requires a Permit to Remove a Wall
Understanding what happens if I remove a wall without a permit starts with why permits exist. Under the Building Code Act, 1992, nobody may construct or demolish a building without a permit, and the Act’s definition of construct covers material alteration, not just brand new buildings.
Toronto states it plainly: a building permit is required for the construction or demolition of a building, an addition, or a material alteration of any building or structure. Taking out a wall that supports a floor, a roof or a beam changes how the house carries its weight, which is a textbook structural alteration.
A permit is not a tax on renovating. It triggers a review of your drawings and inspections at set stages, so someone independent confirms that the work meets the Ontario Building Code. If you want help from a local team, our wall removal toronto service starts with exactly that review.
Responsibility lands on you. The City reminds building owners that they are ultimately responsible for meeting building requirements, even when a contractor does the work.
Unpermitted wall removal is treated seriously because the wall is gone, the paper trail is missing, and nobody has verified what now does the job the wall used to do. That gap is the core of what happens if I remove a wall without a permit.
Skipping the permit also means paying a work without a permit fee later, and a missed permit can resurface as an order to comply building permit notice. Removing a load bearing wall without a permit is the clearest example.
Stop Work Orders and Orders to Comply
In many municipalities enforcement is largely complaint driven. A neighbour, a later inspection or an unrelated permit application can bring the work to the building department’s attention.
Once unpermitted wall removal comes to light, an inspector can issue a stop work order under section 14 of the Building Code Act, and ignoring a stop work order is a separate offence.
The next document is usually an order to comply. The province’s standard form, issued under subsection 12(2) of the Act, names the address, lists each contravention the inspector found, describes the required action and sets compliance dates.
If you receive an order to comply building permit notice, treat it as a legal document with a clock attached. Every order to comply building permit deadline is a date you will be held to.
What an order to comply building permit notice means for you
- Do not hide or remove a posted order. Section 20 makes it illegal to obstruct the visibility of a posted order or to remove it without authorization.
- Ignoring it is an offence. Failure to comply can add a wall removal without permit fine under section 36 of the Act.
- Every order to comply building permit notice is recorded. In Toronto, a Property Information Report shows active permits, violations and work orders for an address, which is how buyers, lawyers and lenders can find them.
So what happens if I remove a wall without a permit and an inspector notices? Stop all work, read the order carefully and contact the building department.
A quick reply with a clear plan to legalize the work puts you in a far better position than silence, and a clear plan also makes the order to comply building permit process easier to close.
Wall Removal Without Permit Fine: What the Law Allows
When people ask what happens if I remove a wall without a permit, the first number they want is the wall removal without permit fine.
Fines under the Building Code Act, 1992 are set by a court after a conviction, and the figures in the Act are maximums, not standard penalties. Under section 36, a person convicted of an offence faces a fine of up to $50,000 for a first offence and up to $100,000 for a subsequent offence. An offence counts as subsequent if there has been any previous conviction under the Act.
Corporations face much higher ceilings. The current Act sets the maximum for a corporation at $500,000 for a first offence and $1,500,000 for a subsequent offence.
That matters if your contractor operates as a company, because for a contractor what happens if I remove a wall without a permit can carry a far larger penalty. Older municipal pages still list $100,000 and $200,000, so check the current Act.
In practice, most homeowners never see a courtroom after unpermitted wall removal. The wall removal without permit fine is the outer limit that gives a municipality leverage, and a wall removal without permit fine of that size is rare. The more common outcomes are orders, extra fees and a retroactive permit.
Prosecution tends to be reserved for people who ignore orders, repeat the behaviour or create an obvious safety hazard.
The Work Without a Permit Fee
Separate from court, many municipalities charge an administrative fee when work starts before a permit exists.
In Toronto, the work without a permit fee equals 50 percent of the permit fees for the project, with a minimum and maximum that the City updates periodically.
You still pay the regular permit fee and the usual processing timelines still apply, so the permit portion of your bill ends up around one and a half times the normal amount before engineering and repairs. The work without a permit fee is calculated from the permit fees, so a large project means a larger fee.
Check the City’s current Building Permit Fees page for the exact limits, because the work without a permit fee differs in other municipalities.
Removing a Load Bearing Wall Without a Permit: The Structural Risks
Removing a load bearing wall without a permit is where a renovation shortcut turns into a safety problem. A load bearing wall carries the weight of floors, walls or the roof above it down to the foundation. Take it out without a properly sized beam, posts and footings, and that weight has nowhere to go.
That is the hardest answer to what happens if I remove a wall without a permit when the wall was structural. Warning signs often show up gradually, which is why people assume everything is fine. Watch for these:
- Sagging or bouncing floors above the opening
- Cracks at the corners of doors and windows or across ceilings
- Doors and windows that begin to stick
- A visible dip in the ceiling line or in a new beam
- Gaps opening between walls and ceilings or floors
In a serious failure, the floor above can drop or part of the structure can collapse, which endangers everyone in the house and anyone working underneath. The risk of removing a load bearing wall without a permit is not only the fine, it is the structure itself.
A compliant job looks very different. Temporary shoring supports the structure during the work. A beam is sized for the span and the loads above it, posts carry the concentrated loads down, and the foundation below is checked so it can accept them.
In many homes a structural engineer prepares or reviews that design, and a firm that handles structural wall removal toronto projects can coordinate that engineering with the permit.
How to tell whether a wall might be load bearing
Before you ask what happens if I remove a wall without a permit, find out what the wall does. Common clues include a wall that runs perpendicular to the floor joists, sits near the middle of the house, has another wall or beam directly above it, or lines up with a beam or posts in the basement. These are clues only.
A qualified professional who inspects the framing is the only person who can confirm it, and earlier renovations sometimes hide structural changes that nobody remembers.
Non Load Bearing Walls: Do You Still Need a Permit?
Many homeowners ask what happens if I remove a wall without a permit when it was only a simple partition. The honest answer is that it depends on your municipality and on what the wall contains.
We cover this on our page about do i need a permit to remove a non load bearing wall, including the checks to run first. It is a very different question from removing a load bearing wall without a permit, where the structure itself is involved.
Toronto’s guidance centres on structural or material alterations, and its interior alterations guidance also addresses plumbing and the creation of a second suite. A wall that looks like a plain partition can still trigger requirements when:
- It contains plumbing, gas lines or ductwork that must be moved or capped, which can bring plumbing or HVAC permits into play.
- It forms part of a fire separation, such as the wall between a garage and living space or between two suites.
- Removing it is part of creating a new bedroom, a basement apartment or another additional unit.
Even where a building permit is not required, the work must still meet zoning rules, and electrical changes in Ontario fall under the Electrical Safety Authority. When in doubt, call the building department and describe the wall.
A five minute call costs far less than a stop work order, and skipping a permit that turns out to be required can still mean a wall removal without permit fine. So the practical answer to what happens if I remove a wall without a permit for a partition is to confirm before you cut.
Hidden Hazards Inside the Wall
Another part of what happens if I remove a wall without a permit is what you uncover once the drywall comes off. Walls hide more than studs.
Electrical wiring, plumbing stacks, gas lines and ductwork often run through them, and cutting into those without a plan can cause electric shock, fire, flooding or gas leaks.
If you want the demolition done safely, read about our wall demolition toronto approach, which pairs testing and shutoffs with the permit process. Unpermitted wall removal skips those checkpoints.
Insurance Problems After Unpermitted Wall Removal
Insurance is the consequence people think about last. If unpermitted wall removal contributes to a collapse, water damage or a fire, your insurer may look at whether the work met code, and the missing permit can complicate or reduce a claim.
The City of Toronto itself lists effects on an insurance claim among the risks of working without a permit, and that is the practical side of what happens if I remove a wall without a permit.
Policies differ, and the wording of your own policy governs. Tell your broker about major renovations before you start. Removing a load bearing wall without a permit raises the stakes of any later claim. Keeping that file also pays off when you sell.
Can You Sell a House With Unpermitted Work?
Can you sell a house with unpermitted work? In most cases, yes, but it rarely goes smoothly. Toronto lists effects on selling a property among the risks of working without a permit, and the same applies to a work without a permit fee that is still unpaid.
Can you sell a house with unpermitted work if a lender is involved? A buyer’s lawyer typically asks the municipality for information about open permits, work orders and violations, and in Toronto a Property Information Report shows exactly that.
An open order to comply building permit notice or a missing permit for a removed wall can lead to a request for a lower price, a holdback, a demand that you legalize the work before closing, or a buyer who walks away. Lenders and insurers may ask questions too.
Sellers should answer questions about known unpermitted work honestly, because hiding it creates its own legal risk.
Can you sell a house with unpermitted work and still get a fair price? Often you can, if you deal with it early. The cleanest route is to legalize the work, close the permit with a final inspection and hand the buyer paperwork showing that the wall was engineered and inspected, which matters most after removing a load bearing wall without a permit.
That turns a red flag into a selling point, and it is what lets you answer can you sell a house with unpermitted work with a confident yes.
How to Fix It: What to Do If the Wall Is Already Gone
If you already know what happens if I remove a wall without a permit and the wall is gone, you still have options. Work through these steps in order.
- Stop all work. Toronto notes that all work must stop while a permit application is processed. Carrying on makes your position worse.
- Do not close up the opening. Leave framing, wiring and plumbing visible. Inspectors may want to see the structure, and finished surfaces may need to be reopened.
- Get a structural assessment. This matters most after removing a load bearing wall without a permit. Ask a structural engineer to review what was removed, what now carries the load and whether a beam, posts or footings are needed.
- Apply for the permit. Submit an application with drawings showing the existing and proposed construction, including structural framing. The regular fees and processing times still apply. Firms that offer wall removal permit services can prepare those drawings and manage the application for you.
- Pay the work without a permit fee. In Toronto, that is the 50 percent administrative fee on top of the regular permit fee.
- Complete corrective work and inspections. Inspectors confirm that the structure, services and finishes meet the Building Code. If an order to comply building permit notice has been issued, meet every item by its date.
- Close the permit. A final inspection confirms the work is complete. Keep the closed permit record with your home documents.
If your wall is structural, the safest next step is a proper assessment. Our team explains the full process for toronto load bearing wall removal projects, from engineer to final inspection.
Acting early is the practical answer to what happens if I remove a wall without a permit. Even if a wall removal without permit fine never reaches a courtroom, a municipality usually responds better to an owner who comes forward than to one who waits for enforcement.
Closing the permit also settles can you sell a house with unpermitted work for the next buyer, because unpermitted wall removal is no longer on the record.
