A systematic review (PROSPERO CRD42021254450) searching four databases to 19 February 2025, with duplicate independent screening, risk-of-bias assessment and certainty grading, on food-based interventions that could reduce household food insecurity (HFI) in Canada. Exposure to food voucher programmes may reduce HFI, but exposure to food box, community gardening, school food, hunting and fishing, and food charity programmes may have little to no effect on HFI. The authors conclude that because HFI is primarily an economic problem, food-based responses are unlikely to have a major impact on overall HFI and a more comprehensive public policy approach is required. This is direct counter-evidence to framing community gardens as a food-insecurity intervention.
