Grey County OPP say a little boy skating on a frozen pond was injured when he was run over by a skid steer.
It happened at a residence on Grey Road 4 in Grey Highlands.
Police say the 4 year old was taken by land ambulance to hospital in London with non-life threatening injuries.
The skid steer was being used to light up the pond for family skating on Monday evening.
The victim's little brother crawled inside the skid steer, and inadvertently put it into motion.
