Canvas Buildings. Built by Canadians.
A canvas building is a versatile, fabric-covered structure designed to provide reliable shelter for agriculture, industrial, commercial, and equestrian applications. Unlike generic temporary shelters, MegaDome canvas buildings are engineered in Canada to handle heavy snow loads, strong winds, and extreme weather conditions. With high-strength oval tube framing and premium fabric membranes, they deliver the durability of permanent buildings at a fraction of the cost. Backed by proven performance and extended warranties, our canvas buildings give farmers, cities, and businesses a dependable space solution that installs quickly and lasts for decades.

Canvas Buildings Projects
Brenda Renewables Composting Facility
The Brenda Renewables Composting Facility in Peachland, B.C. showcases the strength of a MegaDome canvas building in one of Canada’s harshest climates. At 32,000 ft² and designed for a snow load of 5.3 kPa (110 psf), this XP model structure withstands high-altitude conditions at nearly 5,000 ft elevation. Built with galvanized steel framing, concrete beams, and a translucent fabric cover, the facility integrates advanced composting systems including Airfloor® aeration, leachate management, and odor control. This project proves how MegaDome canvas buildings can meet strict environmental regulations while offering long-lasting durability and efficiency.
Brenda Renewables Composting Facility
In Edmonton, AB, Summit Hydro Vac required a custom canvas building to support sludge processing and heavy equipment operations. MegaDome delivered a 60′ × 132′ structure with 12′ bay spacing, complete with two glass overhead doors for natural light, a full-width garage door, and branded green accent striping. Designed for industrial performance, the building houses filtration and centrifuging equipment under a weather-resistant membrane, reducing energy costs and construction time compared to conventional steel buildings. This project highlights the versatility of canvas buildings for demanding industrial applications.
