Serres Harnois

Since 1965, Serres Harnois has been designing and manufacturing commercial greenhouses in Quebec. As a third-generation family-owned business, we have completed more than 20,000 projects, ranging from garden centres and nurseries to large-scale growers. Our product range covers all types of crops and growing operations, including high tunnels, freestanding greenhouses, gutter-connected greenhouses, and glass greenhouses. Our exclusive oval tubing requires fewer arches, meaning less steel and therefore less shade on your crops. Our engineers, agronomists, and project managers support you every step of the way, from design to installation, as well as with after-sales service, maintenance, and repairs.
