Households in Canada and Australia have exhibited similar trends in the gendered allocation of additional child care responsibilities resulting from policy responses to the COVID-19 pandemic. In this article, we employ survey data to analyze the extent to which policy interventions related to COVID-19 have exacerbated gender disparities in child care obligations. We find that existing asymmetrical distributions of child care obligations in Canada and Australia have been amplified during the pandemic, resulting in a disproportionate burden on women. During the pandemic we also find that, in households with children, women tend to report experiencing poorer mental health than men.
