Load-bearing wall removal in Toronto
Toronto's stock runs from 1890s brick semis downtown to 1950s bungalows at the edges, on lots that are rarely wider than 30 feet. In those houses in Toronto, the wall between the kitchen and the dining room is the one that usually comes out, and it usually carries the floor above. Taking out a load-bearing wall is an engineering job with a demolition inside it: the engineer sizes the beam, the posts and the footings, and the crew shores the floor, cuts the wall and lands the steel.
Toronto, on the ground.
In Toronto the usual brief is a second storey on a semi, a rear addition with a new kitchen, or a laneway suite behind a house that already has one. The floor above is shored on both sides, the wall comes out behind dust walls, the beam is set and landed on new footings, and the finishes are patched so the wall was never there.

Paper first.
A load-bearing wall needs a building permit with an engineer's drawing, and the inspector sees the beam and posts before they are closed in. Toronto Building issues the permit, and any design outside the zoning envelope goes to the Committee of Adjustment first, so the zoning check comes before the drawings are final.
- A building permit with engineered drawings is required in every GTA municipality for any wall that carries load.
- The inspector sees the beam and the posts before they are closed in.
- Ducts, plumbing and wiring moved out of the wall are permitted and inspected with their own trades.

| Driver | What we look at |
|---|---|
| Span and load | A long opening under two floors needs a bigger beam and posts on new footings. |
| Flush or dropped beam | A beam hidden in the ceiling costs more than one below it, and the joists above decide whether it is possible. |
| Footings | Posts need something to land on, and that can mean new footings through the basement slab. |
| What is in the wall | Ducts, plumbing and wiring that have to move before the wall can go. |
| Finishes | Matching an old hardwood floor across the opening, or refinishing the whole room. |
No price per wall on this site. The engineer's drawing sets the number.
For a load-bearing wall, yes, from the City of Toronto (Toronto Building), with an engineer's drawing. For a partition wall carrying nothing, usually no. We tell you which at the site walk.
Often. A flush beam sits between the joists so the ceiling stays flat. It costs more than a dropped beam, and what is above decides whether it is possible.
It depends on whether the design fits the zoning envelope. A design inside the by-law goes through as a building permit; one outside it goes to the Committee of Adjustment first, which adds months. [Kam confirms typical Toronto permit timing.]
Often, yes. The shared wall is the engineering question: the new floor loads onto a party wall the neighbour also owns, so the drawings have to show how the load is carried without touching their side. We check the by-law height limit for the street before you commit to drawings.
