The rate of severe food insecurity dropped by one-third among low-income families after a federal child benefit was introduced three years ago, a University of Toronto study has found, and its lead researcher says it’s proof more can be done.

The Canada Child Benefit was introduced by the Liberal government in 2016 as a tax-free monthly payment designed to assist parents with the cost of raising kids.

The study found that although the benefit had not resulted in “huge change” in food insecurity in Canada, it did help families in extreme situations, where they had to compromise the amount of food they ate due to money constraints.

“Our study results are yet another piece of evidence that improving household incomes reduces food insecurity,” Valerie Tarasuk, the study’s senior author, said
