Usually pan-type steel with concrete-filled treads, abrasive nosings and 300mm handrail extensions. $18,000-$32,000 CAD. ### Multi-Flight Exit stairs through several storeys in mid-rise, rental and mixed-use buildings, built inside fire-rated enclosures. $45,000-$95,000. ### Industrial Mezzanine Steel stairs and guards for warehouse and manufacturing mezzanines, with checker plate or grating treads and industrial guards. $28,000-$65,000. ### Hotel Feature Design-led stairs for hotel lobbies, restaurants and showrooms: steel spines, hardwood treads, frameless glass or custom metalwork, following IIDA and ARIDO standards. $65,000-$185,000. ### TSSA Guards Guards and access stairs around regulated equipment, built to the requirements your mechanical engineer sets. ### Fire-Rated Assemblies Stair and guard assemblies inside rated exit enclosures, detailed so the fire separation stays intact. ![Crew setting a steel stair stringer at a commercial site](/images/content/three-crew-members-in-hard-hats-and-safety-glasses.webp) ## Case Study: Willowdale Manor Rental Portfolio We worked with the Willowdale Manor rental portfolio on Yonge Street to replace worn exit and common-area stairs across several buildings in 2023 and 2024. Each building got its own CAD drawing set, and every stair was fabricated and pre-assembled in Etobicoke so tenants lost access for as little time as possible. Temporary stairs kept exits open, and installs were scheduled around move-ins. The property manager kept us on for the full program. We also did The Kingsway Estates on Bloor West, a custom curved staircase with hand-forged detail across the main foyer, and ended up on the property manager’s referral list for more buildings along Bloor West. ## When to Bring Us In - **At design development**, so stair dimensions, structure and finishes are coordinated before tender. - **When a stair package keeps slipping** because an overseas fabricator’s lead time moved. - **For occupied buildings** that need night or weekend installs. - **For feature stairs** where the stair is part of the brand and needs a fabricator who can build what the designer drew. ## Stair Construction Options Compared | Type | Typical use | Treads | Notes | | --- | --- | --- | --- | | Pan-type steel | Exit stairs | Concrete-filled pans | Durable, quiet, easy to finish | | C-channel stringer | Retail, industrial | Checker plate or grating | Fast to fabricate | | HSS stringer | Feature and exterior | Steel, wood or stone | Clean modern profile | | Steel spine | Feature stairs | Hardwood or stone | Design-led, needs P.Eng review | ![Retail egress stair with handrail extensions and tactile indicators](/images/content/detail-of-a-retail-egress-stair-showing-300mm-hand.webp) ## What Moves a Commercial Stair Price | Factor | Effect on price | | --- | --- | | Flights and storeys | More flights, more steel and install days | | Stair type | Pan and channel lower; spine and feature stairs higher | | Finishes | Hardwood, stone, glass and custom metal raise cost | | Engineering | P.Eng stamped drawings itemised separately | | Access and hours | After-hours and occupied-site installs add labour | ## Code and Detail Notes We fabricate to OBC Section 3.4 exits and Section 3.8 barrier-free design: uniform risers, continuous handrails with **300mm extensions**, guards at code height, **abrasive nosing** and **tactile walking surface indicators** where required, and **fire separation** details for rated enclosures. Welding follows **CWB certified welding** practices, and structural elements are reviewed and stamped by a P.Eng where the design calls for it. Commercial railings only?

Know Before You Buy ## The 5-Point Code Compliance Checklist Every Toronto Commercial Stair Must Pass Commercial stairs are inspected harder than residential ones. These are the five points we check on every shop drawing before steel is cut. 1. Point 1 ### Exit width and headroom (OBC 3.4) Exit stairs are sized to occupant load, with minimum clear widths and headroom carried the full length of the flight. 2. Point 2 ### Uniform risers and treads Every riser and run in a flight must match within tight tolerances. Pan-type steel stairs with concrete-filled pans hold those dimensions better than site-built stairs. 3. Point 3 ### Handrails and 300mm extensions Continuous graspable handrails on both sides where required, with 300mm horizontal extensions at the top and bottom of each flight. 4. Point 4 ### Guards and barrier-free details (OBC 3.8) Guard height and openings, abrasive or contrasting nosings, and tactile walking surface indicators at the top of stairs on barrier-free routes. 5. Point 5 ### Fire separation and structure Stairs inside fire-rated exit enclosures need assemblies and penetrations that keep the rating, and structure stamped by a P.Eng where required. Straight Answers ## 4 Concerns GCs and Property Managers Raise Before Awarding a Stair Package The questions we get in pre-award meetings, answered the same way we answer them in person. ### Schedule Will the stair hold up my schedule? Schedule risk: we fabricate in-house with 4 Canadian suppliers, no overseas lead times. Steel, glass and hardwood are sourced locally and the stair is built in our shop while your site keeps moving. ### Insurance What coverage do you carry? WSIB registered, $2M CGL, $500K property damage, certificates on request. ### Drawings How do you handle shop drawings? In our opinion drawings are where commercial jobs go wrong: we issue CAD shop drawings for engineer review before cutting steel. ### Inspection Will it pass occupancy inspection? Built to OBC 3.4 and 3.8; we never promise permit approval but design for first-visit sign-off. Our 5-Step Process ## How Our Commercial Stair Process Works in Toronto, 5 Steps The same five steps on every job, from a one-tread refinish to a curved foyer stair. You see drawings and a written scope before anything is cut. 1. Step 1 ### In-Home Consultation With Material Samples Our lead tech visits your Toronto or GTA property with glass swatches (12mm vs 15mm), wood grain boards and iron patina samples, then laser-measures rise, run and stringer angles. For commercial work this is a site walk with the GC or property manager, reviewing drawings, occupant load and access routes. 2. Step 2 ### Permit-Ready CAD Drawings and OBC Compliance We draw every project to OBC Section 9.8 (residential) or Section 3.4 (commercial): 900-965mm handrail height, 100mm max baluster spacing, 42-inch guard on drops over 600mm. You approve every reveal before metal is cut. We never promise permit approval. CAD shop drawings go to your architect and P.Eng for review and stamping before fabrication. 3. Step 3 ### Written, Itemised Scope Design fee, CAD drawings, materials, fabrication and install are itemised separately in writing. Engineering, finishes, after-hours install and bonding are separate line items. Some Toronto shops over-charge for tread milling thinking clients won't check other quotes. We publish our CAD bands so you can. 4. Step 4 ### In-Shop Fabrication in Etobicoke Under founder Michael Bennett's supervision our crew mills rough-sawn hardwood, TIG and MIG welds every metal joint and dry-fits full spans on shop jigs at our 6,000 sq ft Etobicoke facility. Stringers, pans and guards are welded by our crew; welding follows CWB practices and every part is dry-fit in the shop. 5. Step 5 ### On-Site Install and Walkthrough Clean assembly on site, usually 1 to 4 days, with a vacuumed stair run and a maintenance walkthrough. Trust us, you're in good hands. Installs are scheduled nights or weekends for occupied retail and hospitality sites. Published CAD Pricing ## Commercial Stair Cost in Toronto by Project Type, Published in CAD Commercial stairs are priced per project. Flights, finishes, engineering and after-hours access decide where you land in each band. ### Commercial Stairs (per project) | Small retail egress | $18,000-$32,000 | | --- | --- | | Industrial mezzanine | $28,000-$65,000 | | Multi-flight | $45,000-$95,000 | | Hotel / restaurant feature | $65,000-$185,000 | Engineering review and after-hours install itemised separately. ![Group of stair fabricators reviewing a CAD drawing in the Etobicoke shop](/images/misc/group-of-three-stair-fabricators-in-safety-glasses.webp) No-Obligation, Written Quote ## Every Commercial Stairs Job Backed by a Written Workmanship Warranty WSIB registered with $2M liability coverage, and every project drawn in CAD to OBC 9.8 or 3.4 before we cut anything.

Engineering review, bonding and after-hours install are itemised separately so your cost consultant can compare line by line. ### Which code sections apply to commercial stairs? OBC Section 3.4 for exits and 3.8 for barrier-free design, including handrail extensions and guard heights. Part 3 also governs fire separations for exit enclosures. We draw every stair to these sections and flag anything that needs your architect's or engineer's input. ### Do you provide shop drawings for engineer review? Yes. We issue CAD shop drawings for your P.Eng and architect before steel is cut. Revisions are turned around quickly because the drafting happens in the same building as the fabrication. ### What insurance do you carry? WSIB registered, $2M commercial general liability and $500K property damage, with certificates on request. ### Do you build TSSA guards and fire-rated assemblies? Yes, both are part of our commercial scope. ### Can you install after hours in an occupied building? Yes. Shop pre-assembly lets us install on nights or weekends for retail and hospitality sites. ### Do you handle multi-building programs in North York? Yes. We ran a 2023-2024 stair replacement program across the Willowdale Manor rental portfolio on Yonge Street. ### Do you work with interior designers? Yes. Design-led feature stairs follow IIDA and ARIDO standards and we coordinate directly with the designer. ### What stair types do you fabricate for commercial buildings? Pan-type steel stairs with concrete-filled pans, C-channel and HSS stringer stairs, checker plate industrial stairs, spiral access stairs and feature stairs with hardwood or stone treads. ### How long does a commercial stair package take? Typically 2-3 weeks for shop drawings and review, 3-6 weeks of fabrication, then 1-5 install days depending on flights and access. ### Do you supply abrasive nosings and tactile indicators? Yes. Abrasive or contrasting nosings and tactile walking surface indicators are supplied and installed where OBC 3.8 barrier-free rules require them. ### Can you bid from architectural drawings? Yes. Send the stair sheets and specs and you'll recieve a budget figure, then a firm price after a site walk and measurements.
