In 2014 Food Secure Canada and the J.W. McConnell Family Foundation embarked on a learning journey to explore how food service operations and procurement practices can be changed to help shift systems towards greater sustainability, and how we can scale this work. We learned through eight Institutional Food Fund projects whose work was funded by Foundation grants totalling $450,000 over two years (2014-2016), while engaging with many stakeholders throughout the supply chain and foodsystem. This report presents ten lessons learned about changing institutional food (purchasing and food services) and identifies barriers as well as levers for change in the larger systems of which these institutions are a part. The report finishes with some thoughts and recommendations for scaling this work. We hope the report will inform and inspire institutions, organizations, funders and policy makers to leverage local, sustainable food purchasing by institutions and bring about significant social, economic, health and environmental impacts.
