All of the double-decker buses OC Transpo sent to the garage last week because of a potential wiring problem should be back on the roads today, the city says.
OC Transpo pulled 43 buses off the road — about one-third of its double-decker fleet — for inspection Friday, after a driver reported fumes coming from his bus the night before.
The problem was blamed on an overheated wire harness.
