If you are researching a floating staircase for your Ontario home, this guide covers everything you need to make an informed decision: structural system types, Ontario Building Code requirements, realistic 2026 cost ranges, tread material options, railing systems, and the key questions to ask any staircase company before signing a contract.
What Is a Floating Staircase? Definition and How It Works — Ontario Floating Staircase Guide
A floating staircase — also called an open-riser staircase, cantilevered staircase, or mono-stringer staircase — is a staircase design where the treads appear to be suspended in space without visible side supports. The structural load is carried by a concealed or exposed engineered steel system rather than the traditional closed box stringers on either side of the tread.
The “floating” visual effect comes from two design decisions working together:
- Open risers: There are no riser boards between treads. The gap between each tread is open, allowing light and sightlines to pass through the stair plane.
- Concealed or centralized structure: The steel support runs through the centre of each tread (mono-stringer), along the outside edges (double stringer), or is hidden inside the adjacent wall (cantilevered). In all three cases, the support is not the dominant visual element of the staircase.
The result: an architectural staircase that opens the space around it, allows natural light to pass between floors, and reads as a design element rather than a functional partition. In Barrie and Simcoe County homes above $900K, a well-executed floating staircase is consistently the most commented-on interior feature.
Three Structural Systems: Mono-Stringer, Double Stringer, and Cantilevered
All floating staircases use one of three structural systems. The system determines the visual aesthetic, the engineering complexity, the structural prerequisites, and the cost:
Mono-Stringer Floating Staircase
The mono-stringer (single centre spine) is the most visually dramatic and the most engineering-intensive floating staircase system. A single structural steel beam runs under the centre of every tread, with each tread cantilevered off the beam. The beam connects to the floor structure at the base and to the structural assembly at the top landing.
- Visual character: Maximum openness; treads appear to float with no visible side support
- P.Eng stamp: Required in Ontario (non-prescriptive structural element under OBC Part 4)
- Structural prerequisite: Load-bearing anchor points at base and top; concrete slab minimum 4″ thick if base lands on concrete
- Ontario cost range 2026: $18,000 – $32,000 installed (single straight flight)
At C.O.R.S, the P.Eng stamp on mono-stringer floating staircases is included in the project quote as a standard item — not billed separately. No other staircase company operating in Barrie or Simcoe County matches this standard.
Double Stringer Floating Staircase
Two exposed or slightly recessed steel beams — one on each side of the tread — carry the structural load in a double-stringer system. The treads are visible between the two beams, creating an open visual effect. The side beams can be finished (powder-coated black is most common in Ontario) or left as natural steel.
- Visual character: More industrial aesthetic than mono-stringer; structural beams are intentionally visible
- P.Eng stamp: Typically required for non-standard configurations
- Structural prerequisite: Lower structural demand than mono-stringer; adaptable to more home configurations
- Ontario cost range 2026: $22,000 – $40,000 installed (single straight flight)
Cantilevered (Wall-Mounted) Floating Staircase
The cantilevered system is the most technically complex and most expensive floating staircase option. Each tread is anchored individually into the load-bearing wall via concealed steel brackets or a steel spine hidden inside the wall framing. From the finished side, there are no visible supports at all — only treads appearing to extend from the wall face.
- Visual character: Maximum architectural statement; treads appear to emerge from the wall
- P.Eng stamp: Always required; individual tread anchors must be engineered for point-load
- Structural prerequisite: Load-bearing wall with minimum 2×6 framing; often requires structural reinforcement before installation
- Ontario cost range 2026: $30,000 – $55,000+ installed

Ontario Building Code Requirements for Floating Staircases
Floating staircases in Ontario must comply with the Ontario Building Code (OBC). The core dimensional requirements apply to all staircase types, with one additional requirement specific to open-riser designs:
| OBC Specification | Closed-Riser (Traditional) | Open-Riser (Floating) |
|---|---|---|
| Minimum run (tread depth) | 210 mm | 250 mm |
| Maximum rise per step | 200 mm | 200 mm |
| Minimum rise per step | 125 mm | 125 mm |
| Minimum clear width | 860 mm | 860 mm |
| Minimum headroom | 1,950 mm | 1,950 mm |
| Handrail height | 865 – 965 mm | 865 – 965 mm |
| Guardrail height (to 1,800 mm) | 920 mm | 920 mm |
| Guardrail height (above 1,800 mm) | 1,070 mm | 1,070 mm |
| Nosing projection | 6 – 13 mm | 6 – 13 mm |
| Open-riser sphere test (100 mm sphere) | Not applicable | Required above 600 mm floor height |
The sphere test is the only OBC requirement unique to floating (open-riser) staircases. Any open riser located more than 600 mm above the floor must prevent a 100 mm diameter sphere from passing through the gap between treads. At C.O.R.S, this requirement is resolved at the design stage through tread spacing, a sub-rail, or glass infill — not after installation.
For the complete OBC specification guide and permit requirements by Simcoe County municipality, see our Ontario Building Code staircase guide and our Ontario staircase permit guide.
Floating Staircase Tread Materials: What Works in Ontario
The tread material on a floating staircase is the primary visual element — every tread face is visible from multiple angles. This is a different performance requirement than traditional closed-riser treads, where the nosing and top surface are the main visible zones.
The two dominant tread materials for floating staircases in Ontario:
White Oak (Rift-Sawn, Select & Better)
White oak is the standard C.O.R.S specification for floating staircase treads. With a Janka hardness of 1,360 lbf, rift-sawn dimensional stability across Ontario’s humidity cycles, and compatibility with every stain colour from natural to ebony, white oak delivers the optimal combination of durability and visual versatility on open-riser systems. Detailed white oak tread specifications: white oak stair treads Ontario guide.
Black Walnut
Walnut (1,010 Janka) is the premium alternative for floating staircases where the dark, rich heartwood colour is the design intention. On a mono-stringer or cantilevered system, walnut treads viewed from below (through open risers) and from the side show their depth-absorbing grain in a way that white oak — even stained dark — cannot replicate. The 22% softer Janka rating is acceptable for owner-occupied residential staircases with normal traffic. Detailed walnut specifications: walnut stair treads Ontario guide.

Floating Staircase Railing Options in Ontario
The railing system on a floating staircase can either reinforce the open, minimal aesthetic or undermine it. Here are the railing options C.O.R.S installs on floating staircases in Barrie and Simcoe County:
| Railing System | Visual Character | Per Linear Foot (Installed) | OBC Compliance |
|---|---|---|---|
| Cable railing (stainless wire) | Modern; nearly invisible horizontal lines | $180 – $280 | Compliant at correct spacing |
| Frameless glass panels (10mm tempered) | Maximum openness; invisible guard | $280 – $420 | Compliant; must have top rail or capping |
| Structural glass with post system | Clean; post spacing maintains sightlines | $240 – $360 | Compliant |
| Black steel horizontal bars | Industrial; complements steel stringer | $160 – $240 | Compliant at 100mm max opening |

The C.O.R.S Floating Staircase Installation Process
A C.O.R.S floating staircase project follows six stages from initial inquiry to completed installation:
- Free on-site consultation and laser measurement: We measure your actual rough opening, floor-to-floor height, and structural conditions — not the builder’s drawings. Our laser measurement captures dimensional reality to ±2 mm.
- Shop drawings for approval: Our draftsperson produces a detailed shop drawing package within 5 business days. You review and approve tread dimensions, steel specification, nosing profile, and railing layout before fabrication begins.
- P.Eng structural review and stamp: Our structural engineer reviews the shop drawings, calculates load paths, specifies weld details, and stamps the structural drawings for municipal permit submission. Included in your quote price.
- Steel fabrication and tread milling: The stringer system is fabricated in our Barrie shop. Treads are milled to your exact run dimension, nosing profile, and surface specification.
- Workshop dry-fit assembly: Every tread, bracket, and rail component is assembled in our shop against a geometric mock-up of your opening dimensions. This stage confirms that every piece fits before finishing and delivery. Companies that skip the dry-fit stage encounter fit problems on installation day.
- Delivery and installation: Your staircase components are delivered to your home. Installation for a single straight flight takes one day (2 installers). Your space is operational the same day.

Frequently Asked Questions: Floating Staircase Ontario
Q1: How much does a floating staircase cost in Ontario in 2026?
A single straight mono-stringer floating staircase in Ontario runs $18,000–$32,000 installed with white oak treads. Double-stringer systems run $22,000–$40,000. Cantilevered systems start at $30,000 and can exceed $55,000 for luxury specifications with walnut treads and frameless glass railings. All C.O.R.S prices include the P.Eng stamp and one-day installation.
Q2: Do floating staircases in Ontario require a permit?
Yes. Any new staircase installation in Ontario requires a building permit when the structural system is being changed. Floating staircases using mono-stringer or cantilevered systems require P.Eng-stamped structural drawings as part of the permit application. C.O.R.S includes the P.Eng stamp in every floating staircase quote.
Q3: Is a floating staircase safe for children?
Yes, when properly designed to OBC requirements. The open riser must pass the 100 mm sphere test above 600 mm floor height — a requirement C.O.R.S handles in the design phase through tread spacing or glass infill. The guard height (920–1,070 mm) and baluster/cable spacing meet OBC child-safety requirements at the same standard as traditional staircases.
Q4: How long does a floating staircase installation take?
C.O.R.S’s shop dry-fit process makes one-day installation possible for a single straight flight. The full project timeline from first consultation to completed installation is 6–8 weeks, with shop drawing review and permit coordination as the longest stages.
Q5: Can any Ontario home support a floating staircase?
Not all homes can support floating systems without modification. A mono-stringer requires adequate structural connections at the base (minimum 4″ concrete slab or engineered floor framing) and at the top landing. A cantilevered system requires a load-bearing wall with minimum 2×6 framing. C.O.R.S’s on-site assessment determines feasibility before any quote is issued.
Q6: What is the best tread material for a floating staircase in Ontario?
Rift-sawn white oak (1,360 Janka) is the C.O.R.S standard specification for floating staircase treads. It delivers the optimal combination of hardness, stain versatility, dimensional stability, and Ontario availability. Black walnut (1,010 Janka) is the premium alternative for projects where the dark colour tone is the design priority.
Q7: Does C.O.R.S offer floating staircases outside of Barrie?
Yes — C.O.R.S serves all of Simcoe County at no travel surcharge, including Innisfil, Collingwood, Midland, Wasaga Beach, Angus, and Orillia. GTA locations (Vaughan, Richmond Hill, Brampton, Mississauga) are available by appointment.
Q8: How is a floating staircase different from an open-riser staircase?
The terms are often used interchangeably, but “floating” more precisely describes a structural system where the load is carried by a centre spine or concealed wall anchor, creating the visual impression of treads suspended in space. An “open-riser” staircase may use traditional box stringers with the riser boards removed — it looks open but is not structurally the same as a floating system.
Q9: What glass railing should I choose for a floating staircase in Ontario?
For a mono-stringer floating staircase in Ontario, frameless glass panels (10mm tempered) provide the highest visual compatibility with the minimal steel structure. Cable railing is less expensive and also works well aesthetically. For more detail, see our glass railing Ontario guide.
Q10: Can I get an open-riser floating staircase installed in a renovation?
Yes. Most C.O.R.S floating staircase projects are renovation replacements of existing traditional staircases. The existing staircase is removed, the rough opening is reassessed with laser measurement, and the new floating system is fabricated to the exact dimensions of the existing opening. Structural reinforcement is quoted separately if the structural assessment identifies it as required.
