School buses operating in Oxford County this morning face a 2-hour delay. That's due to a thick blanket of fog covering our area, greatly reducing viability on the roadways. Vehicles travelling from Oxford County to London are also facing a 2-hour delay. Buses travelling to Oxford County's French schools, Ste. Marguerite Bourgeoys and ?cole secondaire Notre-Dame have been cancelled. Keep tuned to Heart FM for the latest on the school bus situation this morning.
