A GO bus hit a guard rail on a ramp from Highway 407 to Yonge Street Thursday night.
Metrolinx say 21 passengers were aboard the Pickering-to-York University bus at the time. OPP Sgt. Kerry Schmidt says the driver suffered minor injuries.
The bus also sustained minor damage near the entrance, and is blocking the ramp. A second bus has been called to replace the damaged bus.
Metrolinx says initial reports suggest the bus crashed into the guard rail because of the icy road conditions.
