Now, perhaps more than ever, people are better understanding the importance of supply chains and food supply to national security.  Greenhouses offer resilient, controlled growing environments capable of producing efficient, targeted, high quality yields.  The Greenhouse Sector has a significant and expanding role to play in the Canadian economy.  Ontario Greenhouse vegetable production alone is a billion dollar industry that has plans to grow at unprecedented rates over the next five years.  The sector is rich with innovation and development. Growers, government agencies, NGOs, consultants, and academia have each contributed to moving Canada's Greenhouse Sector forward.  While there are examples of inter-agency cooperation, no one agency exists that can act as a central hub for the research, dissemination, and knowledge translation - to put innovation into wide practice.  A prospective GREAT Institute and Network would provide links for the coordination of Greenhouse research opportunities and activities, but also the wider education of all Greenhouse stakeholders (including the public).  Such an Institute would leverage the expertise of grower, government, NGO, retailer, consumer, and academic members to train the next generation of Greenhouse professionals for Canadian and wider global employment.
