Engineered for the Ontario farm.

Ontario agriculture runs on margins measured in pennies per litre, pennies per bushel and pennies per bird. Every dollar spent on a barn, a hay shelter or an equipment building has to pay back in herd health, crop quality, equipment life and operator productivity. Building Depot is the Authorized MegaDome Dealer for Ontario — and engineered MegaDome fabric buildings have become the default choice for producers who want a modern, clear-span, naturally lit envelope without the schedule, the cost or the maintenance burden of a conventional wood pole barn or insulated steel structure.

MegaDome fabric buildings combine a hot-dip galvanized steel arch frame with a high-tenacity PVC membrane that's been engineered specifically for agricultural environments. The translucent fabric delivers full ambient daylight from sunrise to sunset, which means lower hydro bills, better animal welfare and dryer, more nutritionally intact hay. The clear-span geometry — widths to 200 feet and beyond — eliminates internal columns, freeing the entire footprint for free-stall layouts, feed alleys, equipment manoeuvres or grain piles. And the inert PVC membrane is chemically resistant to ammonia, manure gases and humidity that corrode conventional painted steel within a decade.

This page is the complete Ontario producer's reference for MegaDome agricultural buildings — from dairy and beef free-stall barns through hay, equipment, grain and equestrian. It walks through the benefits, the construction and installation process, foundation options, engineering, warranty and maintenance so you can plan your project with confidence. Building Depot delivers every project turnkey: engineering, stamped Ontario drawings, municipal permits, foundation construction, in-house concrete, fabric installation and full commissioning under one accountable contract.

Every Building Depot agricultural project follows the same disciplined sequence. It starts with a site visit and operational interview so we understand the herd, the equipment, the workflow and the operator's seasonal calendar. From there our in-house designer produces a stamped engineering package — building dimensions, foundation, ventilation, door layouts and any internal partitions — sized to the application and engineered to the county's snow, wind and exposure category under the Ontario Building Code.

The stamped package goes straight into the municipal permit submission. Building Depot manages the back-and-forth with the local building department and any conservation authority coordination. While the permit is in review, the foundation and steel order goes into production so the project moves the day the permit is issued.

On site, foundation work runs first — pier, slab, L-block or curb wall depending on the application. Steel arches are raised next using a mobile crane and the Building Depot install crew. The fabric membrane is tensioned over the steel, end walls are framed and clad, and the ventilation system is commissioned. The operator gets one accountable contract, one project manager and one weekly status update from contract signing to keys.
