Leciel – Greenhouse Vegetables, a Quebec family business recognized for its commitment to local vegetable production, is celebrating a landmark achievement: 1 million square feet of crops grown under greenhouse. This milestone reflects years of continuous growth and a long-standing partnership with Harnois Greenhouses, which has supplied the majority of the operation’s plastic greenhouse structures — including their latest 65,000 sq ft Luminosa gutter-connected greenhouses.
Built with Harnois Greenhouses’ Luminosa structure, this new complex maximizes interior growing space, optimizes natural light transmission, and ensures superior air circulation — ideal conditions for year-round commercial greenhouse production. The Luminosa gutter-connected design is specifically engineered for Quebec’s climate, with robust columns, high gutter heights, and a poly film roof system that handles heavy snow loads while keeping operating costs low. For a grower like Leciel, whose production calendar leaves no room for downtime, structural reliability and thermal performance are non-negotiable.
This 65,000 sq ft addition brings Leciel’s total footprint past the one-million-square-foot mark, cementing their position as one of Quebec’s largest commercial greenhouse vegetable growers and demonstrating Harnois Greenhouses’ ability to support long-term client growth at scale.
Year-Round Local Production Across Three Strategic Quebec Sites
With three strategically located sites across Quebec, Leciel ensures consistent, year-round local food production, directly strengthening the province’s food sovereignty. The company grows an impressive 6 crops across 20 varieties, including radishes — a category where Leciel holds a market-leading position in Quebec.
Growing under commercial greenhouse structures allows Leciel to produce locally while significantly reducing pesticide use and the carbon footprint associated with imported produce. Their model proves that quality, sustainability, and profitability can go hand in hand.
“It is a great privilege to work with Leciel – Légumes de serres, a company that shares our values of innovation and sustainability. Their commitment to local agriculture is truly inspiring, and we are proud to support their success with custom-engineered greenhouses designed to maximize their year-round yields.”

Steve Bertrand on What Greenhouse Growing Has Changed
“Working with Harnois Greenhouses has transformed the way we grow. By producing under greenhouse, we have been able to significantly reduce our pesticide use and offer Quebecers high-quality, locally grown produce all year long. This greenhouse production model also allows us to reduce our carbon footprint by producing right here in Quebec. These advances not only strengthen our leadership position — they prove that quality, sustainability, and performance can go hand in hand.”
