We prepare commercial estimates and quantity takeoffs across Canada for general contractors, developers, and owners, so instead of a single misleading number, we will break commercial pricing down the way an estimator actually builds a budget: by building class, by city, by CSI division, and with the fit-out and soft-cost layers that separate a real pro forma from a guess.
Commercial construction cost per square foot by building type
Building type is the dominant variable. These 2026 ranges cover hard construction costs for new builds at standard specification, shell plus base building systems:
| Building type | Per sq ft (2026, hard costs) |
|---|---|
| Warehouse / distribution (tilt-up) | $150–$250 |
| Light industrial / flex space | $180–$300 |
| Strip retail / single-storey commercial | $250–$400 |
| Restaurant (shell + full build-out) | $350–$600 |
| Low-rise office (to 4 storeys) | $300–$500 |
| Mid / high-rise office (Class A) | $450–$700+ |
| Medical / dental clinic | $400–$700+ |
| Hotel (mid-scale) | $350–$550 |
| Multi-residential (wood-frame, 4–6 storeys) | $250–$400 |
Why the spread? Structure and services. A warehouse is a simple envelope with minimal interior systems. A medical clinic packs plumbing into every exam room, redundant HVAC, and specialized electrical, which is why mechanical, electrical, and plumbing scope is where commercial budgets are won or lost, and why a dedicated MEP estimate anchors every serious commercial budget we prepare.
Commercial construction cost by city
Using low-rise office as the benchmark building, here is how major Canadian markets compare in 2026:
| City | Low-rise office, per sq ft (2026) |
|---|---|
| Toronto / GTA, ON | $360–$540 |
| Vancouver, BC | $350–$530 |
| Calgary, AB | $300–$450 |
| Edmonton, AB | $290–$440 |
| Ottawa, ON | $300–$460 |
| Montreal, QC | $280–$430 |
| Winnipeg, MB | $270–$410 |
| Halifax, NS | $270–$420 |
Toronto and Vancouver carry the same 15 to 25 percent premium over mid-country markets that we document across residential work in our guide to the cost to build a house in Canada. On the commercial side, the premium is driven as much by development charges and longer approval timelines as by labour rates.
Where the money goes: hard-cost breakdown by CSI division
Commercial estimates are organized by CSI MasterFormat division. Here is how hard costs typically split on a low-rise commercial build:
| Cost category | Share of hard cost |
|---|---|
| Sitework, excavation & utilities | 8–12% |
| Foundations & concrete structure | 12–18% |
| Structural steel / superstructure | 10–16% |
| Building envelope (cladding, glazing, roofing) | 12–18% |
| Mechanical & plumbing (HVAC, sprinklers) | 12–18% |
| Electrical & low voltage | 8–12% |
| Interior finishes & partitions | 12–20% |
| Elevators / conveying (where applicable) | 2–5% |
| General conditions, GC overhead & profit | 10–15% |
Note the last line: general conditions and general contractor markup claim 10 to 15 percent of every commercial budget, which is why owners increasingly commission an independent estimate before tendering. Knowing the real cost of the work is the only leverage you have when GC bids arrive. That is the core of our commercial estimating services, and for plant, warehouse, and process buildings, our industrial estimating services apply the same discipline.
Tenant fit-out and leasehold improvement costs
Base-building numbers exclude the interior fit-out, which is its own budget. For 2026, leasehold improvement costs in Canada typically run:
| Fit-out level | What it covers | Per sq ft (2026) |
|---|---|---|
| Basic / open plan | Paint, carpet, minimal partitions, existing services reused | $40–$70 |
| Standard office fit-out | Offices and meeting rooms, kitchenette, lighting, HVAC rebalancing | $70–$120 |
| High-end / client-facing | Feature ceilings, glazing partitions, millwork, AV, upgraded finishes | $120–$220+ |
| Restaurant / food service | Kitchen equipment, ventilation, grease management, dining build-out | $200–$450+ |
| Medical / dental fit-out | Exam room plumbing, medical gas, imaging shielding, specialty HVAC | $180–$400+ |
Tenants negotiating leases should know these numbers cold, because landlord tenant-improvement allowances in Canada typically cover only $25 to $60 per square foot, leaving the tenant to fund the gap.
Soft costs: the 20 to 30 percent on top
What drives commercial construction cost up or down
- Structural system. Tilt-up and pre-engineered steel are the economy options; cast-in-place concrete and long-span steel carry premiums.
- Mechanical specification. Standard rooftop units versus VRF or hydronic systems can move the MEP line by 30 to 50 percent.
- Envelope quality. Curtain wall glazing prices multiples above insulated metal panel or block-and-brick.
- Site conditions. Poor soils, remediation, tight urban sites, and crane logistics all land in the budget before a single wall goes up.
- Escalation and market timing. Canadian non-residential construction prices have risen steadily; carry escalation on any project tendering more than six months out, and benchmark against current indices, not last year’s bids.
- Approvals timeline. Every month of carrying cost during permitting is real money; markets with slow approvals are more expensive than their labour rates suggest.
How developers actually budget a commercial project
A disciplined commercial budget is built in layers, and each layer is an estimate refined as design advances. It starts with a Class D order-of-magnitude number from per-square-foot benchmarks like the tables above, used to test feasibility. At schematic design it becomes a Class C elemental estimate. At design development, a Class B estimate priced by trade. And before tender, a Class A pre-tender estimate built from a full quantity takeoff of the drawings, the number the GC bids get measured against. Skipping straight from a napkin number to tender is how projects end up value-engineering in a panic after bids come in 20 percent over. A proper quantity takeoff at each gate is the cheap insurance against that.
How to compare GC bids like an estimator
- Demand a common bid form broken down by division, so every GC prices the same scope the same way.
- Compare general conditions line by line: supervision, temporary services, hoisting. This is where bids hide margin.
- Check allowances and cash allowances: a low bid with thin allowances is not low, it is deferred.
- Read the exclusions list twice. Site servicing, permits, commissioning, and bonding are the classics.
- Benchmark every division against an independent pre-tender estimate: if the winning bid’s mechanical line is 25 percent under your estimate, that is a change-order engine, not a saving.
- Confirm escalation and schedule assumptions match the contract dates.
