There will be no school bus service for thousands of students across Windsor-Essex on Wednesday morning.
The consortium that provides that service has decided not to run the buses in the City of Windsor or in Essex County.
Environment Canada has issued a freezing rain warning for much of southwestern Ontario ahead of a major ice storm which is expected to move into the region later in the morning.
It predicts up to 10 mm of freezing rain and strong winds with gusts of up to 70 km/h.
