OPP say a man has suffered life-threatening injuries following a crash that sent a vehicle with children into water.

First responders were called to the scene around 6 p.m. on Saturday at Haldimand Road 3 in Nanticoke.

A witness reported that a vehicle had left the roadway, rolled into a pond, and was partially submerged as it landed on its roof.

"Resusitation efforts were conducted at the scene," said Rod LeClair of the OPP. "Ambulances transported him to the hospital with life-threatening injuries."

Paramedics transported the male driver to a local hospital with life-threatening injuries.

An eight-year-old boy and five-year-old girl were passengers in the vehicle and not injured. Police have identified the 38-year-old male driver from Woodstock as the father of the children.

According to OPP, a family member was following in a separate vehicle. They stopped at the scene and were able to pull the children and man from the vehicle with the help of other witnesses before first responders arrived.

Police continue to investigate the incident.

While it's unclear what caused the car to leave the roadway, OPP plan to crack down on distracted and dangerous driving for the rest of the long weekend.

"No phone call or text is worth your life or anyone elses," said LeClair.

Weather is not beleieved to be a factor in the collision.
