Removing a load-bearing wall in Toronto: the permit, the beam and the City fees

Taking out the wall between the kitchen and the dining room is a common way to open up a Toronto house. When the wall is load-bearing, it holds up part of the floor or the roof above, so something has to take over that job before it comes out. That something is a beam, and the beam and the permit are what this guide is about.

Do you need a permit to remove a load-bearing wall?

Yes. Toronto Building lists “adding or removing walls (i.e., changing room sizes and/or uses)” among the structural or material alterations that need a building permit. The list doesn't separate bearing walls from other walls.

How to tell if a wall is load-bearing

Read the framing, not the wall. A thick wall or a hollow sound when you knock tells you nothing about what it carries. Look from below and above:

• The joists: from the basement or the attic, see whether the floor or ceiling joists run across the wall, with their ends resting on it, or run alongside it.
• What sits under it: a beam, a line of posts or a foundation wall roughly below the wall in the basement is a strong sign it carries load.
• What sits over it: a wall stacked on top of it on the next floor usually means the load comes straight down through it.
• Where it is: in many Toronto semis and detached houses, a wall near the middle of the house and parallel to the front carries the floor. Treat exterior walls and a semi's shared wall as load-bearing.

Joists that run parallel to the wall, with nothing landing on it and nothing under it, point the other way. When the framing is hidden, a small inspection hole in the ceiling settles it before anyone sizes a beam.

What replaces the wall: beam, posts and footings

The beam picks up the joists the wall used to carry. Each end of the beam then becomes a concentrated load that has to travel down through the house to the foundation, so the design is never just the beam. It covers three things:

Flush or dropped?

A dropped beam hangs below the ceiling, with the joists resting on top of it. It is simpler to install and leaves a bulkhead across the room. A flush beam sits up in the joist space, with the joists hung off its sides, so the ceiling stays flat. It means opening more of the ceiling, and it often has to be steel to fit the depth.

What the City asks to see

Toronto Building's interior-alterations guide sets out the drawings. For a wall removal, the important ones are:

• Floor plans, fully dimensioned, for each level, existing and proposed, showing the interior partitions and the structural framing above.
• Cross sections showing the existing and proposed construction, down to the footing and foundation details.
• Construction details for the assemblies involved.
• Forms: the Application to Construct or Demolish, Schedule 1 Designer Information, the Rental Renovation Licence Screening Form and, for engineer-sealed sheets, the Assumption of Responsibility for Engineering Content form. If pipes move, a Plumbing Data Sheet is added.

A good set goes a step further and shows where each new load lands, the size of every new footing and how the floor is held up while the wall comes out, so the contractor and the inspector are working from the same sequence.

Owners who are exempt from the designer qualification can draw for themselves and state the reason for the exemption on Schedule 1. The drawings still have to show the beam, the posts and the load path, and they go through the same review.

What it costs

There are three parts to the cost: the City's fees, the design and drawings, and the construction.

The City's fees

In 2026, interior alterations to a house are $11.53 per m² of the area affected, with a $214.79 minimum for all work. The minimum covers up to about 18.6 m², or 200 sq ft.

• Ducts and plumbing: if ducts or pipes move, the City's 2026 fees are $214.79 flat for ductwork alterations and $23.20 per plumbing fixture in a single-family house.
• Zoning certificate: the City counts a house application as complete only when it includes an issued Zoning Applicable Law Certificate and all fees are paid. For alterations to houses that certificate is $644.38. Ask Toronto Building whether an interior-only job needs one.

Design and construction

The design fee depends on what the wall carries and whether an engineer's seal is needed; we quote ours in writing before any drawing starts. The construction cost depends mostly on these:

• The span: a wider opening needs a deeper or stronger beam.
• Steel or engineered lumber: steel usually costs more and takes more work to place.
• Flush or dropped: a flush beam means opening and refinishing more ceiling.
• The posts and footings: a new footing means cutting and patching the basement slab.
• What runs through the wall: ducts, pipes and wiring have to be rerouted. Electrical work is reported to the Electrical Safety Authority, separately from the building permit.
• Finishing: patching floors where the wall stood, new drywall and paint.

Timeline: from drawings to a closed permit

1. 01
   Site visit

   The framing is read from the basement and the attic, the opening measured and what the wall carries photographed.

2. 02
   Design and drawings

   The beam, posts and footings are sized and drawn as one set, with the forms.

3. 03
   City review

   Complete applications for a detached, semi-detached or row house with up to two units are reviewed within 10 business days. Interior alterations to such a house can go through Express Services, where the City's goal is 3 business days, if no permit for a new house or an addition is open on the property; the full fee is paid when you apply. Party-wall work is accepted there with extra submission requirements. An incomplete application has no review clock.

4. 04
   Construction

   The floor above is shored, the wall comes out, and the beam, posts and footings go in.

5. 05
   Inspections

   If new footings are poured, call for the footings inspection when the forms are in, before the concrete. Then call for the structural framing inspection once framing and the rough-in of plumbing and HVAC are done, and the final interior inspection when the work is complete. Inspections happen within two business days of your request.

6. 06
   Close the permit

   The owner books the final inspection that closes the permit.

If the wall already came out without a permit

It can usually be put right by applying for the permit now. The beam and posts that are there get documented, the ceiling is opened where needed to see them, and the drawings either show that they work or design the fix. The City issues the permit only once the work meets the rules, which can mean more work or undoing some.

• The extra fee: 50% of the permit fee or $214.79, whichever is greater, up to $29,456.99 per permit in 2026. Up to about 37 m² (400 sq ft) affected, half the fee is under $214.79, so the extra fee is the $214.79 minimum. At 40 m² it is $230.60.
• Work stops: all work has to stop while the application is processed.
• Possible extra work: the City notes there may be more structural or mechanical work to do, or work to undo.

The City warns that work without a permit can affect selling your property or making an insurance claim, so it's worth settling before either comes up.

Before demolition in an older house

Health Canada notes that before 1990, asbestos was mainly used to insulate buildings and homes, and that it may still be in older plaster, vermiculite insulation, drywall, putty and caulking. Before opening up a wall or ceiling in an older Toronto house, have a professional test for asbestos. Leave any vermiculite alone; if the work will disturb it, hire professionals trained to handle asbestos.

Where to start

Photograph the wall, the basement ceiling under it and the attic over it if you can get there, and measure the opening you want. Our load-bearing wall removal page has a beam planner that shows the likely beam type for your span. From the photos, Rocco can usually tell whether the wall carries load, or say what to open up to check, and what the permit set will need.
