On April 30, 2025, VegPro International officially inaugurated its new 5.2-hectare Vermax glass greenhouse in Sherrington, Quebec, a project delivered in partnership with Harnois Greenhouses, a Canadian manufacturer of turnkey greenhouses solutions. 

This semi-enclosed greenhouse is designed to produce leafy greens year-round. The new facility is part of a broader $135 million investment. VegPro has implemented advanced systems for rain and snow water collection, closed-loop water recirculation and energy optimization. As a result, the greenhouse will use up to 90% less water than conventional field-grown lettuce.

VegPro is also introducing a new, crunchier lettuce variety to meet evolving consumer tastes. 

“This project is a testament to VegPro International's confidence in Harnois Greenhouses,” said Harnois President Patrice Harnois. “We're proud to have delivered a state-of-the-art facility that showcases Canadian innovation and engineering. With our partner Growa, we’ve set a new benchmark for greenhouse performance and energy efficiency in North America.” 

Designed with carbon neutrality in mind, the facility integrates Harnois’ patented technologies to reduce greenhouse gas emissions by nearly 2,000 tonnes annually while significantly cutting energy costs.

Construction is complete, and operations are now underway.
