Terrahills builds non-combustible steel industrial buildings, warehouses, cold storage and food-grade facilities across Ontario under a single contract: foundations, rigid frame structure, metal roofing and exterior envelope, and the Ontario Building Code Part 3 compliance that ties them together.
Most steel building projects in Ontario are assembled from parts. A manufacturer sells the frame and ships it. A concrete contractor pours a foundation designed by someone else. A roofer arrives once the steel is up. An engineer stamps drawings for one scope and not the next. When the anchor bolts do not line up with the base plates, four companies are on the phone and none of them owns the problem.
Terrahills delivers the whole building. We take the geotechnical report, design the foundation to the frame reactions, procure and erect the structure, close the envelope, and hand over an occupied building. The non-combustible classification is our responsibility, not a box for you to tick after the fact. The same delivery covers cold chain and food-grade facilities, where the envelope is the refrigeration system and cleanability is a regulatory requirement.
Our capability includes EU-GMP certified pharmaceutical and life-science facilities, requiring the highest standards in clean-room design, HVAC segregation, mechanical systems and regulatory compliance. The same controlled-environment discipline we bring to food-grade and cold chain manufacturing plants.
Six stages, one contract
These pages follow the order the building actually goes up. Each covers the decisions that stage forces, what it costs to get wrong, and how it connects to the stage on either side.
Markets we know building by building
One sector in one market, with the soils, approvals, funding tiers and pipeline that actually change the job.
Delivered Industrial
The Ramara Industrial Park (100,000 sq ft, our own multi-unit development in Simcoe County) is the clearest demonstration: raw land through servicing, structure, envelope and tenant occupancy under one contract.

Industrial cost bands, Ontario 2026
| Building type | Hard cost, $ / sq ft | Basis | What moves it |
|---|---|---|---|
| Warehouse: dry shell | $75 – $180 | 2026 GTA benchmark | Clear span, eave height, envelope spec, slab thickness, dock count |
| Distribution facility | $170 – $480 | 2026 GTA benchmark | Clear height for racking, dock density, floor flatness, ESFR sprinklers, automation |
| Cold storage: cooler / freezer | $240 – $420 | Ontario 2026 benchmark | Refrigeration plant (25–35%), IMP thickness, heated freezer slab, doors and controls |
Hard costs only. Land, servicing, stormwater, development charges, permits, fire-protection water supply and soft costs sit outside every band. Industrial figures are published 2026 Ontario construction cost benchmarks, GTA; regional Ontario typically prices below the GTA band. A Class C estimate against your scope is the number to plan on.
