The Ontario Medical Association is calling for mandatory vaccines for teachers and other school staff.
O-M-A president Dr. Adam Kassam says since children under 12 currently can't receive COVID-19 vaccines, they rely on others to keep them safe.
The doctors also want to see mandatory indoor masking, which is part of the province's back-to-school plan.
The O-M-A has also called for mandatory vaccinations for health-care workers and for a vaccine certificate system.
Premier Doug Ford has said he won't mandate vaccines.
