Sunday buses have been running in Belleville for a couple of months …and people are jumping aboard. Transit chair councillor Jack Miller told city council last night that the demand has been great enough to add an extra hour. Miller says the service has been averaging abut 800-passengers each Sunday. Sunday buses will begin running at nine in the morning instead of 10 A.M. Miller says regular bus service will also be extended during the month of December, running until 10-at night.
