Replacing a commercial door in Ontario in 2026 costs $1,800–$3,800 installed for a hollow metal door and frame, $2,800–$6,500 for an aluminum-and-glass storefront door, and $2,500–$7,000 to add a power operator. Here's the full installed price breakdown by door type, what pushes quotes up, and the code items that catch Ontario building owners off guard.
Average Commercial Door Costs in Ontario (2026)
| Door type | Installed cost | Notes |
|---|---|---|
| Hollow metal door only (existing frame) | $1,200–$2,200 | Door slab + hardware swap |
| Hollow metal door + frame | $1,800–$3,800 | Most common back-of-house replacement |
| Fire-rated assembly (45–90 min) | $2,500–$5,000 | Labelled door, frame, and hardware |
| Aluminum storefront door | $2,800–$6,500 | Tempered glass, closer, panic hardware |
| Power operator (accessibility) | $2,500–$7,000 | Per opening, incl. actuators and wiring |
| Overhead/roll-up service door | $3,500–$12,000+ | Size- and spec-dependent |
Hardware is where quotes diverge. A basic cylindrical lever set is a few hundred dollars; a code-compliant package with panic device, closer, kick plates, weatherstripping, and keying can add $800–$2,000 per opening. If your building runs on a master key system or access control, coordinate before ordering — retrofitting electrified hardware later is far more expensive.
What Affects Your Quote
Frame condition. If the existing hollow metal frame is square, rust-free, and solidly anchored, a door-only swap saves $600–$1,600. Rusted-out frames at grade level — extremely common on Ontario loading docks thanks to salt — force full replacement.
Fire ratings and labels. Every component of a rated assembly must carry a matching label, and the installation itself must preserve the rating. This is not a place to economize: an unlabelled door in a rated wall is an automatic fire inspection failure.
Accessibility requirements. Renovations trigger current OBC/AODA requirements: clear width, threshold height (13 mm max), opening force, and lever or panic hardware. Many storefront replacements now include a power operator — see our accessibility and glazing guide for what applies when.
After-hours installation. Retail and medical tenants often can't lose their entrance during business hours. Evening and weekend installs add labour premiums but avoid lost revenue — usually the right trade.
Repair or Replace?
Rule of thumb we give Waterloo Region property managers: if the door slab is straight and the frame sound, repair — closers, hinges, latches, weatherstripping, and glass can all be renewed piecemeal, and a $300–$600 service call buys years. Replace when you see frame rust-through at the base, a warped or delaminating slab, repeated closer failures from frame misalignment, or when accessibility or fire-rating upgrades are triggered anyway. Our repair-vs-replace guide goes deeper.
DIY vs. Professional: The Real Comparison
Hanging a residential door and hanging a commercial assembly are different trades. Hollow metal frames must be anchored and grouted plumb within tight tolerance or every piece of hardware fights you forever; panic hardware and closers must be adjusted to code-specified opening forces; and fire-rated assemblies legally require correct installation to keep their listing. Facility teams do fine swapping hardware like-for-like — full openings belong with a commercial door installer.

Frequently Asked Questions
How much does a commercial steel door cost installed in Ontario?
A hollow metal door with frame, commercial hardware, and installation runs $1,800–$3,800 in Ontario for 2026. Fire-rated assemblies sit at the upper end and beyond ($2,500–$5,000) because the door, frame, and hardware must all carry matching labels and be installed to maintain the rating.
How much does a glass storefront door cost?
A medium-stile aluminum storefront door with tempered glass, closer, and panic hardware typically costs $2,800–$6,500 installed in Ontario. If the surrounding aluminum framing also needs replacement, budget more — framing is priced per square foot and often exceeds the door itself.
Are commercial doors required to be accessible in Ontario?
Yes. The Ontario Building Code and AODA set requirements for clear width (typically 850 mm+), maneuvering clearances, opening force, and hardware operable with a closed fist (levers or panic bars, not knobs). Power door operators are mandatory in many occupancies and renovations — budget $2,500–$7,000 installed per opening.
How long does commercial door installation take?
A straight swap of a hollow metal door into an existing sound frame takes 2–4 hours. Door plus frame replacement is usually a half-day to full day per opening, including cutting out the old frame, grouting/anchoring the new one, and hanging and adjusting hardware. Storefront framing work can run 1–2 days.
Do fire-rated doors need inspections in Ontario?
Yes — the Ontario Fire Code requires fire door assemblies to be maintained in operating condition, and NFPA 80 annual inspections are the accepted standard. Propped-open fire doors, missing labels, and field-drilled holes are the most common violations found during fire inspections — and all void the door's rating.
