The COVID-19 pandemic has led to significant education disruption in Ontario. This has included mass and localized school closures, multiple models of educational provision and gaps in support for students with disabilities. The unequal distribution of school closures and pandemic- associated hardships, particularly affecting low-income families in which racialized and Indigenous groups, newcomers and people with disabilities are overrepresented, appear to be deepening and accelerating inequities in education outcomes, wherever data have been collected. Further, there are health risks associated with closures including significant physical, mental health and safety harms for students and children. Modelling suggests long-term impacts on students’ lifetime earnings and the national economy. There are substantial data gaps on the impact of closures on Ontario’s children. However, existing information and analysis can inform strategies to minimize further pandemic disruptions to children’s education and development. Identifying or tracking areas where students are facing the greatest challenges in the wake of COVID-19 and implementing systematic supports to address pandemic-associated educational harms are critical to minimizing the overall impact and supporting recovery.
