摘要

A retrenchment of globalization has called into question tariff-free trade at a time when global exchange in food has never been higher. These politics undermine assumptions of uninterrupted global produce flows and raise the question of how to supply cities with produce if trade is restricted, including by climate change. Canada’s largest wholesale food market, the Ontario Food Terminal, is an example of regional food system infrastructure for fresh produce that operates at scale. Here we find that this infrastructure, along with regional agricultural land, connects farmers to consumers and supports food security. Our evidence-based analysis highlights the policy imperative to protect regional foodsheds for cities and offers planners an example of scaled-up regional food system infrastructure that has functioned for decades.
