Commercial glass pricing in Ontario for 2026: replacing a sealed unit in an existing storefront frame costs $700–$1,800 installed, full storefront framing systems run $75–$160 per square foot, and emergency board-ups add $300–$600. This guide covers the numbers, the code triggers, and how to decide between repairing units and replacing systems.
Average Commercial Glass Costs in Ontario (2026)
| Item | Typical 2026 price |
|---|---|
| Sealed unit (IGU) replacement, standard size | $700–$1,800 installed |
| Oversized / laminated / security units | $1,800–$4,500+ |
| Emergency board-up (after hours) | $300–$600 |
| Storefront aluminum door (glass, closer, panic) | $2,800–$6,500 |
| Full storefront system (frame + glazing) | $75–$160 / sq ft |
| Window film (security / solar / anti-graffiti) | $8–$20 / sq ft |
The single biggest price lever is glass spec: a clear tempered IGU is the baseline; low-E coatings, laminated security interlayers, spandrel, and custom tints each step the price up. The second lever is access — ground-floor panels swap quickly, while anything needing a lift, crane, or suction rigging above grade multiplies labour.
What Affects Your Quote
Frame condition. If your aluminum framing is square and thermally sound, replacing only the glass saves enormously. Racked frames, corroded sills, and single-glazed 1970s systems argue for system replacement — especially with energy code requirements applying to new storefront work (our energy code guide explains when).
Lead time. Sealed units are custom-manufactured to measure — typically 5–10 business days in Southern Ontario. That's why break-ins get a board-up first and glass second. Planned replacements (foggy units, seasonal refreshes) can be batched: measuring five units on one visit and installing on another is cheaper per unit than five separate calls.
Safety glazing requirements. Replacement glass in doors, sidelites, and near-floor glazing must be tempered or laminated to current OBC — even if the original wasn't. Quotes that seem suspiciously cheap sometimes spec annealed glass where safety glazing is required; that's a liability you don't want.
Protection against the next impact. If the break came from a vehicle, quote bollards with the glass — two or three units at the right spacing cost less than one more storefront claim. For repeat vandalism, security film or laminated glass hardens the target; see our anti-graffiti film guide.
Unit Replacement vs. System Replacement
Replace units when frames are sound: foggy IGUs, single broken panels, seal failures. Replace the system when you're fighting the framing itself — chronic leaks at sills, condensation streaming down interior aluminum in winter (no thermal break), or a re-clad/renovation that triggers current energy performance anyway. A hybrid path many Waterloo Region owners take: replace failed units now, and budget system replacement into a planned facade refresh 3–5 years out.

Frequently Asked Questions
How much does it cost to replace a storefront glass panel in Ontario?
A tempered sealed unit (IGU) in an existing aluminum storefront frame runs $700–$1,800 installed for typical sizes in 2026. Oversized panels, laminated or security glass, and units above grade cost more. Emergency after-hours board-up plus later glass replacement adds $300–$600 for the board-up visit.
What does full storefront replacement cost per square foot?
Complete storefront systems — new thermally broken aluminum framing plus glazing — run $75–$160 per square foot installed in Ontario. A typical 300 sq ft retail storefront therefore lands between $22,000 and $48,000 depending on frame system, glass spec, and doors.
Why is my commercial window foggy, and what does it cost to fix?
Fog between panes means the sealed unit's edge seal failed — the fix is replacing the IGU, not the frame: $700–$1,800 per unit for standard sizes. Failed units also lose their insulating value, so replacing them typically pays back partly through heating costs.
Is tempered glass required for storefronts in Ontario?
Glass in doors, sidelites, and glazing near walking surfaces must be safety glazing (tempered or laminated) under the Ontario Building Code. Older storefronts with annealed glass in hazardous locations don't have to be proactively replaced, but any replacement work must meet current code — which is why quotes always specify tempered.
Does building insurance cover broken storefront glass?
Usually yes for vandalism, break-ins, and vehicle impacts, subject to your deductible — which is often $1,000–$5,000, close to the replacement cost of a single unit. Many owners pay small breaks out of pocket to protect claims history. We provide the itemized documentation insurers ask for either way.
