IntroductionFood insecurity-the inadequate access to food due to financial constraints-affects 1 in 6 households in Canada, with serious health implications. Family benefit programs supplementing income have shown potential in mitigating the risk of food insecurity, but there is little understanding of their protective effects. The authors aimed to estimate the impacts of the additional Canada Child Benefit provided to families with children aged <6 years on household food insecurity.MethodsThe authors sampled 28,435 households receiving Canada Child Benefit with children aged <8 years from the Canadian Income Survey 2018-2020 fielded in 2019-2021 and analyzed in 2022. Households without children aged <6 years were 1:1 propensity-score matched to those with children aged <6 years, who received up to $1,068 in additional Canada Child Benefit per child annually. The authors compared the 2 groups' 12-month food insecurity likelihood after matching. Subsample analyses were performed by household income, housing tenure, and household type.ResultsReceipt of the additional Canada Child Benefit ($724 on average) was associated with 2.89 (95% CI=1.35, 4.42) percentage points lower probability of experiencing food insecurity among recipients with children aged <6 years (from 24.30% to 21.42%). The association was similar across socioeconomic subgroups and significant among all but high-income earners and mortgage-free homeowners.ConclusionsThe authors found plausibly causal evidence that the more generous Canada Child Benefit for Canadian families with young children reduces their probability of food insecurity. Increasing benefits for economically disadvantaged households, characterized by low incomes, single parenthood, and renting (versus owning), may improve the program's efficiency and equity in supporting families' food security.Copyright © 2023 American Journal of Preventive Medicine.
