The Grey Bruce Labour Council has concerns about the province's back to school plans.
GBLC President Kevin Smith said the plan is underfunded and jeopardizes the safety of students and educators.
Smith added that all four of the major education unions in Ontario, which represent the province's elementary and secondary teachers and education workers, are all condemning the plan.
The unions represent 200,000 teachers and education workers who are expected to return to school in September.
It's estimated that billions of dollars will be needed for enhanced cleaning and disinfecting of schools, additional custodial staff, masks and personal protective equipment, and health and safety training for staff and additional educators.
