The single most common question we get: what does a fabric building actually cost in Ontario, turnkey and installed? Prices vary by size, engineering (snow and wind loads), foundation type and end use — but the ranges below reflect real 2025-2026 project quotes across the province, not manufacturer list price.
Turnkey Cost by Building Size
Turnkey means engineering, permit-ready drawings, foundation, frame, membrane and installation — everything except the electrical fit-out. For a hot-dip galvanized MegaDome on a concrete pier foundation in Southern Ontario: 40x60 lands roughly $95K-$140K, 60x100 lands roughly $180K-$260K, 80x160 lands roughly $340K-$460K, 100x200 lands roughly $550K-$780K. Northern Ontario and heavy snow zones (Muskoka, Sudbury, Thunder Bay) add 8-15% for engineering upgrades.
What's Included in a Turnkey Quote
- Ontario-stamped structural engineering (P.Eng)
- Permit-ready drawing set for municipal submission
- Hot-dip galvanized steel arches and base channel
- Architectural-grade PVC membrane (15-year warranty)
- Concrete foundation — pier, slab or L-block per design
- Complete mobilization, crane and installation crew
- Continuous ridge vent + gable ends
- Warranty registration and municipal sign-off
What Drives Cost Up (or Down)
Snow load is the biggest single driver — a Muskoka site can add 10-20% versus a Toronto site of the same footprint. Foundation choice matters: L-block ecology blocks are the cheapest, concrete piers are the standard, and full slab is the most expensive. End walls and doors are a common overspend zone — a manual sliding door is a fraction of the cost of a fully-hydraulic bi-fold aircraft door. Insulation and heating packages can add $30-$120/sq ft, so specify only what the operation actually needs.
Fabric vs. Steel (PEMB) Cost
For clear-span warehouse and storage applications up to 120 feet wide, a MegaDome delivers 30-45% lower turnkey cost than a comparable pre-engineered steel building — driven by lighter foundations, faster erection and less structural steel per square foot. Full lifecycle including one 18-year membrane re-skin, fabric still comes in 30-40% ahead of steel over a 30-year horizon in Ontario.
How to Get a Fixed Quote
Building Depot returns a written, fixed turnkey quote within 24 hours of a scoping call. We need three things to price accurately: intended use, approximate dimensions (or the operation the building has to house) and the site municipality. That's it — everything else we work out with you before contract.
