The 401 eastbound was closed for several hours Tuesday morning after a single vehicle rollover in Milton.
Emergency officials were called at 4:07 a.m. after the minivan rolled over near Trafalgar.
OPP sergeant Kerry Schmidt says the 15 year old passenger of the vehicle had to be extricated from the vehicle and was airlifted to hospital with unknown injuries.
The 48 year old driver managed to get out on his own and was taken to hospital with minor injuries.
Schmidt speculated that there may have been a mechanical failure or a blown tire that caused the rollover.
