Tweed Farms

Tweed Farms, located in Niagara-on-the-Lake, Ontario, was once the world's largest legal cannabis greenhouse, boasting 350,000 square feet of indoor cultivation space in 2014. Owned by Canopy Growth Corporation, it expanded to nearly 1,000,000 square feet by 2018. However, in November 2021, the facility was closed due to profitability challenges, resulting in layoffs and staff relocations. This site represents a significant chapter in Canada's cannabis industry, making it a point of interest for tourists and researchers alike.
