Two people were airlifted to the hospital, provincial police say, following an overnight collision in New Tecumseth’s Alliston neighbourhood.

OPP say the two-vehicle collision was reported shortly after midnight on Thursday.

It happened in the area of Highway 89, between Concession Road 4 and County Road 13.

Police shut down those roads overnight, but they have since been opened.

According to Simcoe County Paramedics, a 29-year-old driver was alone in one of the vehicles while the other had three passengers; a 19-year-old male, an 18-year-old male and 18-year-old female.

The female remains in local hospital with minor injuries, paramedics say, while all of the males were transported to a Toronto-area hospital, two by air and one by road.

All three males are reported to have suffered serious, but non-life-threatening injuries.

An investigation into the cause of the collision is ongoing.
