Canadians increasingly want produce that is fresh, safe, and grown close to home—but our climate rarely cooperates. Modern controlled-environment agriculture (CEA) is changing that equation. This talk explores how energy-efficient greenhouses like Whole Leaf’s 11-acre facility in Coaldale now supply millions of heads of lettuce year-round with 90 percent less water than field production and zero insecticides or herbicides. The speaker will examine:
The market shift toward “Made-in-Canada” fresh produce and its economic impact
Key technologies—climate control, hydroponics, automation, and combined heat-and-power (CHP) systems—that make northern greenhouses viable and competitive
Sustainability gains: Reduced land use, water recirculation, and CO₂ utilization
How local production shortens supply chains, lowers spoilage, and improves food security for Southern Alberta & Canada.
