A major crash on Highway 401 has sent three people to hospital in serious condition.
It happened just before 1 a.m. on Thursday on the eastbound express lanes at Yonge Street.
OPP Sgt. Kerry Schmidt said the crash involved three transport trucks and two other vehicles.
One of the tractor-trailers flipped over, trapping a man inside for roughly 25 minutes.
Toronto fire and paramedics pulled the man, believed to be in his 40s, from the vehicle. He was then taken to a trauma centre with serious but not life-threatening injuries.
Another man was also rushed to a trauma centre with serious but not life-threatening injuries.
A third victim was taken to hospital with minor injuries.
Highway 401 eastbound express lanes were closed at Allen Road for the majority of the night. They reopened just around 6 a.m. The westbound express lanes are shut down at Highway 404.
Schmidt said the highway is expected to fully reopen at 8:30 a.m.
