The wrong wood on a staircase looks wrong for years. The right wood looks right for decades — and performs well the whole time. Here is a data-driven guide to the five best wood species for staircase treads in Ontario, with the specific numbers you need to make the right call for your project.
For detailed hardwood species data, visit the Canadian Wood Council (CWC) — C.O.R.S sources only grade-verified hardwoods for Ontario staircase projects.
The One Number That Matters Most: Janka Hardness
Janka hardness measures the force required to embed a steel ball halfway into wood. For stair treads — surfaces that take direct foot impact, furniture moves, and pet claws every day — hardness directly predicts how long the finish and surface hold up under traffic.
Industry consensus: a minimum Janka rating of 1,000 lbf is required for residential stair treads. Below this threshold, the wood dents too easily under daily use for a tread application to make sense.
| Species | Janka Hardness (lbf) | Natural Colour | Stainability | Relative Cost |
|---|---|---|---|---|
| Hickory | 1,820 | Creamy white with tan streaks | Moderate (inconsistent grain) | Medium |
| Hard Maple | 1,450 | Creamy white to pale tan | Poor with dark stains (blotches) | Medium |
| White Oak | 1,360 | Light to medium brown, olive cast | Excellent (all tones) | Medium |
| Red Oak | 1,290 | Warm reddish-pink tones | Good (warm tones only) | Low–Medium |
| Walnut | 1,010 | Rich chocolate brown | N/A (use clear finish) | High |
White Oak: The Best All-Around Choice for Ontario Staircases
White oak is the dominant stair tread species in Ontario custom staircase projects right now — and has been for three years running. At 1,360 lbf Janka, it is durable enough for heavy residential use. Its open grain accepts stain in any direction: cool grey, natural light brown, warm medium brown, ceruse/wire brush. The ray figure gives it natural character that reads well in both stained and clear finishes.
The key technical advantage of white oak over red oak is its tyloses content — tiny structures in the wood’s pores that reduce liquid absorption by approximately 30% compared to red oak. This makes white oak the better choice for open-riser staircases where the tread nosing is exposed from below and for floating stair designs where moisture management matters more.
Best for: Contemporary, transitional, and modern interiors. Open-riser and floating stair designs. Any project where stain colour flexibility is important.
C.O.R.S specification standard: 38 mm kiln-dried white oak, nosing profiled to project spec, waterborne stain (client-approved), two coats waterborne polyurethane satin finish — applied and cured in our workshop before delivery.
Hard Maple: The Hardest Domestic Hardwood, With One Catch
Hard maple at 1,450 lbf is harder than white oak, making it the most durable domestic hardwood for tread applications where maximum impact resistance is the priority. Its tight, uniform grain and pale creamy colour look exceptional in natural or very light finishes — clean, minimal, contemporary.
The catch: Maple’s dense, non-porous surface resists liquid stain penetration unevenly. Attempting any medium to dark stain on maple results in blotchy, unpredictable colour — not recoverable without removing the stain entirely. Maple performs beautifully in clear, natural, or light tints. For any specific stain colour — grey, brown, dark — choose white oak instead.
Best for: Pale, Scandinavian, or minimalist interiors. Natural or clear finish applications. Projects where maximum hardness is the primary criterion.
Walnut: The Premium Choice When Appearance Leads
Walnut at 1,010 lbf just clears the residential tread hardness threshold — it is not the most durable choice, but it is far from fragile. What walnut offers instead is unmatched natural aesthetic impact: rich chocolate-brown to espresso heartwood with flowing grain, requiring no staining to look luxurious. In a contemporary staircase with matte black steel and glass railing, natural walnut treads are a deliberate luxury specification.
Cost reality: Walnut typically costs 25–40% more than white oak per tread in Ontario. For a 14-tread staircase, the material cost premium is $700–$1,400 over white oak. Whether this is warranted depends entirely on whether walnut’s natural dark tone is the design intent — if you are planning to stain the treads to any colour, white oak is a better specification for the cost.
Best for: Prestige applications, luxury interiors, projects where natural dark wood tone is the design direction.
Red Oak: The Traditional Standard That’s Still Viable
Red oak at 1,290 lbf has been the default residential stair tread species in Ontario homes for 30+ years — it is widely available, competitively priced, and performs well. The reason it has been displaced by white oak in contemporary Ontario staircase projects is not performance: it is the warm, reddish-pink undertone in the wood that resists the cool and neutral stain directions that current interior design favours. Dark or grey stains applied to red oak pick up an orange undertone that clashes with contemporary palettes.
Best for: Traditional or warm-palette interiors. Projects coordinating with existing red oak floors. Applications where budget is the primary constraint.
Critical Specification Note: Tread Thickness
All species above are specified at 38 mm minimum thickness for stair tread applications. This is a hard requirement, not a preference. Standard hardwood flooring planks are 19–20 mm thick — this is insufficient for a stair tread for three reasons: structural span capacity across the opening, nosing profile depth (a proper rounded or chamfered nosing requires adequate material depth), and refinishing longevity over the tread’s service life.
If a contractor or supplier quotes you stair treads at 19–20 mm, they are quoting flooring planks repurposed as treads. This is a false economy that produces inferior treads structurally and aesthetically. Specify 38 mm minimum — 44 mm for longer unsupported spans in open-riser designs.

Frequently Asked Questions
What is the most popular wood species for stair treads in Ontario in 2026?
White oak is the most specified tread species in Ontario custom staircase projects by a wide margin. Its stainability, Janka hardness of 1,360 lbf, and natural ray figure make it the best all-around choice for both contemporary and transitional interiors. C.O.R.S projects show white oak as the tread species on approximately 70% of custom staircases delivered in the past three years.
Is red oak or white oak better for stair treads?
White oak is better for most contemporary and transitional Ontario interiors. It accepts cool, grey, and neutral stain tones cleanly — which red oak resists due to its warm pink undertones. White oak also has better moisture resistance due to its tyloses content. Red oak is still a good choice for traditional interiors coordinating with existing red oak flooring.
Can I use hardwood flooring planks as stair treads?
No. Standard flooring planks are 19–20 mm thick — insufficient for proper stair tread function. Stair treads require a minimum of 38 mm thickness for structural span capacity and nosing profile depth. Using flooring-thickness material produces treads that are too thin, cannot be properly profiled at the nosing, and have insufficient depth for the refinishing cycle over the tread’s service life.
How often do hardwood stair treads need refinishing?
With proper maintenance and care, polyurethane-finished hardwood treads typically last 10–15 years before showing wear that warrants refinishing. Hardwax oil finishes require more frequent maintenance (nosing refreshing every 1–2 years) but are easier to spot-repair. Solid hardwood at 38 mm can be sanded and refinished 3–5 times over its service life.
What is the minimum Janka hardness for stair treads?
Industry consensus sets 1,000 lbf as the minimum acceptable Janka hardness for residential stair treads. Below this threshold — which disqualifies softwoods like pine (380 lbf), Douglas fir (660 lbf), and most softwoods — the wood dents too easily under daily residential foot traffic to be a practical tread specification.
