Commercial Greenhouses for Sale in Alberta
Looking for commercial greenhouses for sale in Alberta? Whether you operate a large-scale vegetable farm near Lethbridge, a floriculture operation in Edmonton, or a garden center in Calgary, Harnois Greenhouses designs and builds structures engineered to perform in Alberta’s demanding climate, from heavy snowfall and freeze-thaw cycles to intense summer heat.
As a Canadian manufacturer with over 60 years of experience, we deliver greenhouse kits, turnkey greenhouse projects, and full-service support to growers across the province. Our mission is simple: give you greater predictability, better yields, and a faster return on investment.
Why Alberta Growers Choose Harnois
Alberta’s growing conditions are among the most challenging in North America. Short summers, extreme temperature swings, and significant snow loads demand structures built to a higher standard. At Harnois, every commercial greenhouse sold in Alberta is engineered specifically for these realities.
All our structures come with stamped engineering plans designed to meet local building codes, snow load requirements, and wind resistance standards. The Ovaltech freestanding greenhouse, for example, withstands snow loads up to 80 inches and wind speeds up to 155 mph, critical performance thresholds for Alberta producers. Our in-house engineering team works directly with you to ensure your structure is sized, oriented, and equipped for your specific site and crop.
Beyond structural performance, we manufacture our greenhouses entirely in Canada, which means faster lead times, locally adapted designs, and a direct relationship with the team that builds your structure.
Our Greenhouse Structures Available in Alberta
We offer four main commercial greenhouse lines to serve Alberta growers across all scales and crop types.
Full-Service Support from Design to Harvest
Buying a commercial greenhouse in Alberta is not just a structural decision, it’s an operational one. That’s why Harnois operates as a full-service partner, not just a manufacturer. Our team manages every phase of your project: needs assessment, engineering, manufacturing, delivery, installation, and post-installation support.
We provide integrated greenhouse equipment, heating, ventilation, irrigation, lighting, and climate control, all sourced and coordinated through a single supplier. This plug-and-play approach reduces project complexity and ensures that every system works together from day one.
Our growers don’t just buy a structure. They gain a long-term partner committed to their operation’s success, with ongoing technical support and training available after installation.

Greenhouse Production Applications in Alberta
Alberta’s agricultural sector supports a wide range of greenhouse crops. Harnois structures are used across floriculture, produce growing, young plant propagation, and soft fruit production. Each crop has specific requirements for temperature, humidity, lighting, and irrigation, and our team helps you match the right structure and equipment to your specific needs.
Compared to open-field farming, greenhouse production in Alberta delivers higher crop density, better product quality, reduced pesticide use, and consistent yields season after season. According to Agriculture Canada, protected horticulture is one of the fastest-growing segments of Canadian agriculture, and Alberta represents a significant opportunity for growers willing to invest in controlled environments.
