A foggy start to the day has pulled school buses off the road.
School buses in zones 1 through 8 have been cancelled for this morning because of the fog, however buses will be back on the roads this afternoon to bring students home from school.
The cancellation affects school buses serving the Lambton Kent and St Clair Catholic District School Boards, as well as the Providence Catholic School Board.
Environment Canada has issued a fog advisory, warning of near zero visibility on the roads in some areas.
Travel is expected to be hazardous due to reduced visibility. If visibility is reduced while driving, slow down, watch for tail lights ahead and be prepared to stop.
