Ontario Court Justice William Fitzgerald also gave Frank Reynolds, 65, of Wellands, a one-year driving licence suspension.
On June 5, Fitzgerald found Reynolds guilty of dangerous operation of a motor vehicle causing bodily harm.
Reynolds testified he did not know he had struck Joan Sherritt with his Chevrolet Tahoe about 3:20 p.m., on Jan. 30, thinking instead it was a chunk of ice in the tire well.
He also said he did not know Sherritt was underneath his SUV as he continued his left turn in front of the store, dragged her for a distance of 20 metres, and then drove backwards, running her over again.
"It seems to me that the operation of the vehicle in the manner I described constitutes a marked departure from a responsible, prudent driver," said Fitzgerald in his decision.
The crash was captured on Walmart security video.
Sherritt told the court she suffered facial injuries, including four broken teeth, and is still in pain.
