There's already been a serious crash this long holiday weekend in our region.
Grey County OPP are investigating a crash involving a horse and buggy and pick up truck near Tara.
The Grey Bruce Line between Grey Road 16 and Side Road 3 has been re-opened after police closed that stretch of road for several hours today.
Police say the accident happened around 7:30 AM this morning.
They say a GMC Sierra pick up was travelling north along the Grey Bruce Line when the driver attempted to pass a north bound horse and buggy.
While passing, the truck made contact with the buggy.
Police say four of the five occupants in the horse and buggy received minor injuries.
A male teen however, has been airlifted to Sunnybrook Hospital in Toronto with life threatening injuries.
Both horses involved in the crash are injured as well, and a vet was called to the scene.
Neither occupant in the pick up truck were injured.
No further details have been released.
The investigation continues.
