Class A office fit-out cost per sq ft in Toronto
Interior fit-out of Class A office space in the Greater Toronto Area.
Short answer (November 2026): Class A office fit-out in the GTA costs $160–$265 per sq ft in hard costs, before soft costs, contingency and HST (Altus Group 2026 Canadian Cost Guide). For example, a Class A office fit-out of 25,000 sq ft comes to $4.0M – $6.6M in hard cost.
A Class A office fit-out of 25,000 sq ft
| Hard cost (25,000 × $160–$265) | $4.0M – $6.6M |
| Soft costs at 20% | $800,000 – $1.3M |
| Contingency at 10% | $480,000 – $795,000 |
| Indicative total | $5.3M – $8.7M |
Included: the building above grade, including foundations.
Not included: GST/HST, site development, parking, land and financing. Soft costs and contingency above are illustrative assumptions; change them in the calculator.

Per square metre, what's included and who pays
Per square metre. One square metre is 10.764 square feet, so multiply a per-square-foot rate by 10.764. In 2026 that puts a Class A fit-out in the GTA at about $1,722 to $2,852 per m² and Class B at about $1,184 to $1,615 per m² (Altus Group). To convert an area, divide square feet by 10.764: 10,000 sq ft is about 929 m².
Another benchmark. Cushman & Wakefield's 2026 guide puts the Toronto average at $204.45 per sq ft, rising to about $307 once furniture, IT, audio-visual and soft costs are added.
What's included. Hard cost covers the construction trades (drywall, doors, electrical, mechanical, finishes, millwork) plus the contractor's general requirements and fee. Electrical is usually the largest single trade. Furniture, IT, audio-visual and soft costs sit on top, and can add roughly half again to a hard-cost budget. See our guide to OFOI, OFCI and CFCI for keeping those packages coordinated.
Landlord allowance vs tenant cost. In a typical Toronto office lease, the landlord may offer a tenant improvement (TI) allowance, and the tenant pays anything above it. Allowances are negotiated deal by deal, so we don't quote a typical figure. Price the fit-out you need, compare it with the allowance, and fund the gap. Check which items the allowance can pay for and how to draw it.
How an owner's rep keeps a fit-out on budget
- Set the all-in budget first: construction, furniture, IT, audio-visual, fees, permits, contingency and HST in one number.
- Check the base building early: electrical capacity, HVAC zoning, sprinklers and washrooms can add cost before any finishes go in.
- Level the bids line by line, so exclusions don't hide in a low number.
- Control changes: price each late design change before approving it. See our change order guide.
- Plan the permit: a Toronto building permit can set the start date. See our permit timeline post.

What does the cost of an office fit-out include?
Construction (hard) cost covers the trades plus the contractor's general requirements, fee and contingency. Furniture, IT, audio-visual and soft costs are usually extra; in Cushman & Wakefield's 2026 Toronto example they lift the total from about $202 to about $307 per sq ft.
Who pays for an office fit-out, the landlord or the tenant?
It depends on the lease. Landlords often contribute a tenant improvement allowance, and the tenant pays any cost above it. Allowance levels are negotiated deal by deal.
