The cost of an Ontario industrial building is decided by a short list of variables, most of them settled long before anyone prices steel. Understanding which ones move the number is more useful at the planning stage than a dollar-per-square-foot figure with no building attached to it.
What actually moves the number
Two 50,000 sq ft warehouses can differ substantially in cost without either being badly bought. The variables below account for most of the spread, roughly in order of how much leverage each carries.
How estimates get produced
Construction estimates are classified by the quality of information behind them. A Class C order-of-magnitude estimate is produced from concept information and carries a wide contingency. Class B works from developed design. Class A comes from complete documentation and is the basis for a fixed price.
Asking for a Class A number at concept stage produces a padded figure, not a precise one. The useful sequence is a Class C estimate to test feasibility, design development, then a Class B estimate to confirm the project still works before committing to full documentation. Terrahills produces Class A through C estimates and quantity surveys as part of preconstruction.
Where budgets get lost
Not usually in the building. In the items that sit outside the quoted structure: servicing extensions, stormwater management, site remediation on a previously used parcel, development charges, hydro capacity upgrades, and the carrying cost of a longer-than-expected approvals process.
A steel building quotation covers the building. A project budget covers the project. The gap between the two is the single most common reason an industrial development runs over, and it is why we produce the estimate against the whole scope rather than the structure alone.
| Building type | Hard cost, $ / sq ft | Basis | What moves it |
|---|---|---|---|
| Warehouse: dry shell | $75 – $180 | 2026 GTA benchmark | Clear span, eave height, envelope spec (through-fastened vs IMP), slab thickness, dock count |
| Distribution facility | $170 – $480 | 2026 GTA benchmark | Clear height for racking, dock density, floor flatness, ESFR sprinklers, automation infrastructure |
| Cold storage: cooler / freezer | $240 – $420 | Ontario 2026 benchmark | Refrigeration plant (25–35% of total), IMP thickness, heated freezer slab, doors and controls; blast-freeze exceeds $450 |
| Long-term care home | ≈ $545 – $940 | MLTC 2025 policy, derived | Funding tier: $436,000/bed (southern Ontario) to $750,000/bed (GTHA) at 800 sq ft/bed, capped at $1,100/sq ft eligible |
| Purpose-built rental, ≤ 12 storeys | $245 – $390 | 2026 GTA benchmark | Structure type (wood, steel, concrete), below-grade parking, unit mix, energy tier for CMHC MLI Select points |
Hard costs only: structure, envelope, mechanical, electrical and finishes. Land, site servicing, stormwater, development charges, permits, fire-protection water supply and soft costs sit outside every band. Industrial and multi-residential figures are published 2026 Ontario construction cost benchmarks, GTA; regional Ontario industrial typically prices below the GTA band. Cold storage is an Ontario 2026 industry benchmark. Long-term care is derived from the Ontario Ministry of Long-Term Care 2025 Capital Funding Policy ceilings. A Class C estimate against your actual scope is the number to plan on.
