A four year old is being treated at a Hamilton hospital after she was ran over by an ATV in Norfolk County.
OPP Constable Ed Sanchuk says a 32 year old man was sitting on the vehicle with a two year old on his lap on Saturday afternoon.
The two year old pressed the throttle and caused the vehicle the reverse quickly.
Although the driver tried to avoid the four year old who was playing in the driveway behind him, the vehicle collided with the child and rolled over.
The four year old was air-lifted to a Hamilton hospital with serious injuries while the two year old also suffered minor injuries.
An investigation in ongoing.
