Panelized Wall Framing in Ontario (2026): Factory-Built Wall Panels and Floor Cassettes vs Stick Framing, Crane Day, Engineering, Foundation Tolerances and How Quotes Differ
Framing & Building Systems
Panelized Framing: The Same Wood Walls, Built Indoors and Delivered on a Truck
A panelized house is an ordinary wood-frame house whose walls, and sometimes floors, are built in a shop instead of on your lot. The studs, plates, headers and sheathing are the same; the difference is where the nailing happens and how the pieces arrive. It can save framing time in bad weather. It can also cost you a crane day and a pile of grief if the foundation is out by an inch. Nobody we checked publishes Ontario panel prices, so this page explains how to compare the quotes instead.
What It Is, and What It Is Not
Wall panels are framed walls, sheathed, sometimes with the openings cut and the housewrap on, built flat on a table in a plant and shipped stacked on a flatbed. Floor cassettes are the same idea for floors: joists, rim and subfloor built as a panel and craned into place. On site, a crew stands the walls, nails them together, sets the floors and roof, and the house carries on like any other framed house.
It is not a SIP. A SIP is a foam core glued between two skins, and the panel itself is the structure and the insulation; it sits outside the Part 9 prescriptive tables. A panelized wall is studs, and you still insulate it like a stick-framed wall. It is not modular either. A modular house leaves the factory as finished boxes certified to CSA A277; a panel leaves as a flat wall. The prefab homes page covers the boxes.
| Way of building the structure | Level | Range | Source and note |
|---|---|---|---|
| Stick framing on site, labour only | Level 2 | $14 a sq ft | our planning number, inside a GTA framing contractor’s range |
| Stick framing on site, labour and materials | Level 2 | $40 a sq ft | our planning number, inside a Canadian finance guide’s $30 to $60 |
| Panelized walls and floors | Level 1 or 2 | quoted per job | no published price found |
| SIP base frame package | Level 1 | about $37 to $39 a sq ft | an Ontario SIP package seller, derived; no assembly |
| Modular, delivered and installed | Level 3 to 4 | about $296 to $338 a sq ft | an Ontario prefab cottage seller, derived; foundation extra |
| Crane, per day | Level 2 item | $700 to $1,500 | a Hamilton crane company |
| Boom truck and crew, half day | Level 2 item | $900 to $1,400 | a calculator site, for setting a 21-truss house |
October 2026, before HST, per sq ft of floor area. A panel price may be Level 1 (panels delivered) or Level 2 (panels set and assembled); ask which before comparing it with a framer’s number.
Why Ontario prices are all over the map: the framers and price guides we checked for this page quoted very different prices for the same framed house, and nobody published a panel price at all. Framing labour runs from $7 a sq ft (a Canadian proptech blog) and $9 (a GTA framing contractor) to $16 to $25 or more per sq ft of footprint (an Ontario framing contractor). Per floor area against per footprint is half that gap; GTA against elsewhere, and what is included, is the rest. Budget $40 a sq ft for framing with materials (our planning number) and get two or three quotes, panel and stick, on the same written scope.
Where Panels Save Time, and Where They Do Not
The win is the walls. A shop crew building on a table with jigs and a roof over its head works faster than a crew on a muddy deck in November, and the walls come out straight. Once the panels arrive, the walls can go up much faster than stick framing on site, which matters when you are racing the snow or paying rent somewhere else.
The rest of the house does not speed up much. The roof, the windows, the mechanical rough-ins, the insulation and every finish after that take as long as they always did. Framing is often quoted as 15 to 20 percent of the build budget (a Canadian proptech blog), so even a big saving on framing touches a small share of the whole job. Think of panels as a faster first act, not a shorter play.
Panels also lock in the design early. Moving a window after the plant has built the wall is a field change with a saw, and changing your mind about a wall location can mean a panel that no longer fits anywhere.
The Foundation Has to Be Right First
A stick framer can fudge a foundation that is a little out of square, because he cuts the plates to fit what is there. A panel was built in a plant to the dimensions on the drawing. If the foundation is long, short, out of square or out of level, the panels do not care what the drawing said, and the crew on site is left shimming, trimming or rebuilding.
- Get the foundation checked against the drawings before the panel plant releases production: length, width, diagonals and top-of-wall level.
- Ask the panel company what tolerance it needs, in writing, and give it to the foundation contractor before the footings go in.
- Find out who pays when it does not fit. That should be in both contracts.
I build ICF houses, so on my builds the basement and exterior walls are concrete, and the floors and roof are wood: engineered I-joist floors bearing on the ICF walls and trusses on top. Whatever sits on a foundation, wood floors or panels, the top of that wall has to be where the drawing says it is.
Engineering and the New Bracing Rules
The 2024 Code added Subsection 9.23.13, bracing for resistance to lateral loads. Walls now have braced wall bands and braced wall panels, three lateral-load categories (Low, High and Extreme, with most of Ontario in Low), more nailing for sheathing, more anchorage, and walls with required braced wall panels must be continuously supported by floor joists, blocking or rim joists. Designers state the bracing on the drawings. The wall bracing page explains it in plain words.
For a panel plant that is good news and homework. Good news, because nailing schedules are easier to get right on a table than on a ladder. Homework, because the panel drawings have to carry the bracing, nailing and anchorage your permit drawings show. Ask the panel company who prepares the panel drawings, whether a BCIN designer or an engineer reviews them against your permit set, and how the hold-downs and anchors line up with the foundation. Big window walls and walkouts are where braced wall length runs short, so expect the plans examiner to ask about those walls first.
Crane Day, Access and How the Quotes Differ
Panels come on a flatbed and go up with a crane or a boom truck. A Hamilton crane company charges $700 to $1,500 a day, and a boom truck and crew for half a day runs $900 to $1,400. If the truck cannot get close to the foundation, the panels get carried by hand, and that is when the time saving goes back on the truck with them. On Georgian Bay lots, GeorgianBaySiteworks.ca handles site work and crane and truck access.
Here is a stick-framing baseline for a 2,400 sq ft house: labour only at our $14 planning number is 2,400 x $14 = $33,600; labour and materials at $40 is 2,400 x $40 = $96,000. A panel quote can only be compared with that if it covers the same scope. Add a crane day of $700 to $1,500 if the panel quote leaves it out, and the site crew if it is panels delivered only.
- Panels delivered, or panels set? Level 1 or Level 2 changes everything.
- Walls only, or walls and floors? And who does the roof: trusses from a truss plant, or rafters on site?
- Sheathing, wraps and window openings: on in the plant, or done on site?
- Crane, delivery and the setting crew, each as its own line.
- Engineering and panel drawings, and who answers the plans examiner.
Put the panel quote and the stick quotes side by side on those five lines and the real difference shows up. The house framing cost page has the full framing breakdown, and the home building systems guide links every other system.
Questions people ask
What is panelized wall framing?
Wood-frame walls, and sometimes floor cassettes, built and sheathed in a plant, shipped flat and craned onto your foundation. The structure is the same studs and sheathing as a stick-framed house.
Is panelized framing cheaper than stick framing?
We found no published Ontario price, so nobody can tell you that in general. It is quoted per job. Compare it with stick quotes on the same scope, including the crane, delivery and setting crew.
How is a panelized house different from a SIP house?
A panelized wall is studs and sheathing that you insulate afterwards. A SIP is a foam core between two skins, and the panel is the structure and the insulation; it is not covered by the Part 9 prescriptive tables.
How is panelized different from modular?
Modular houses leave the factory as finished three-dimensional boxes certified to CSA A277. Panels leave as flat walls and floors, and the rest of the house is built on site.
Do wall panels have to meet the new bracing rules?
Yes. The panels are wood framing under Section 9.23, including the new Subsection 9.23.13 on bracing. The panel drawings should carry the bracing, nailing and anchorage shown on your permit drawings.
Compare panels, sticks, SIPs and modular on one sheet
The building system cost comparison calculator takes the same house as wood frame, SIP, ICF, log, timber frame and modular and brings each one to Level 4. If you have a panel quote and a stick framing quote that do not cover the same scope, the $99 review puts up to three on one grid.
