Removing a Load-Bearing Wall in Toronto: Cost, Permit and How It's Done

Why this is the most common structural request

Many Toronto and GTA houses built before 1990 have full-height walls between the kitchen, dining room and living room. Families today want open sightlines and more natural light, and taking out the wall is the quickest way to get them. The catch is that many of these walls carry the floor or roof above, so removing one is a structural job, not a demolition job.

Is my wall load-bearing?

You cannot tell for sure by looking, and only an engineer can confirm it. These are the clues that raise the odds:

• The wall runs perpendicular to the floor joists above, or sits near the middle of the house.
• It sits directly over a basement beam, a steel post or another wall on the floor below.
• Roof framing, a second storey or a chimney rests on or near it.
• It is an exterior wall, which is always load-bearing.
• In older homes, it is a thick plaster-and-lath wall that was part of the original framing.

What the process looks like

1. 1**Engineering assessment.** The engineer finds what the wall carries, then stamps a beam design specifying steel, LVL (engineered lumber) or a built-up wood beam.
2. 2**Permit.** The stamped drawings go to the City with the building permit application.
3. 3**Pre-work.** Dust barriers go up, floors and furniture are protected, and any electrical or plumbing in the wall is identified and re-routed.
4. 4**Temporary shoring.** Posts and beams on both sides carry the load while the wall comes out.
5. 5**Wall out, beam in.** The wall framing is removed in sections and the new beam is lifted into place on supporting posts.
6. 6**Inspection and finishing.** The City inspects the beam. After sign-off, drywall, paint and floor transitions are completed.

What it costs

A typical opening costs $8,000 to $25,000. The spread comes from a few things:

Permit fees are billed at cost on top of the quoted price, either as a separate line or invoiced once the amount is known. HST is 13% on the full pre-tax price.

Flush beam or drop beam?

A drop beam hangs below the ceiling. It is simpler, quicker and cheaper, and it works well when you can live with a bulkhead or when the ceiling is high. A flush beam sits between the ceiling joists, so it is invisible from below and gives the cleanest look, but it needs a beam sized to fit within the joist depth and adds engineering and framing work. Which one works for your house is decided in the engineering phase.

How long it takes

• **3–6 weeks** for engineering and the permit before any work starts.
• **3–7 days on site** for a single opening: demo, shoring and beam, inspection, then finishing.
• **1–2 weeks** for larger openings or several walls in one project.

What goes wrong with DIY and unpermitted jobs

• Undersized beams and posts that sag over time or crack the ceilings above.
• Loads that land on floor joists or basement walls never designed to carry them.
• Insurance problems after a claim, because unpermitted structural work can void coverage.
• Buyer and inspector red flags when you sell, which can mean paying for engineering after the fact.
