Delta 3 greenhouse in East Ladner, southwest British Columbia, may be the world's largest cannabis greenhouse. As of 2018, the greenhouse is owned by Pure Sunfarms, an Emerald Health Theraputics–Village Farms International joint venture. In early 2018, it was licensed to expand to 1,100,000 square feet (100,000 m2) (25 acres), enough to produce 75 metric tons of cannabis annually. The company owning the greenhouse has options to expand to another two greenhouses; combined they would produce 300 metric tons per year, equal to roughly half of Canada's entire recreational cannabis consumption at the time nationwide legalization commenced in 2018.
