Stupar, 50, struck and killed the seven-year-old girl with his car near the Walsh's home in the neighbourhood of Leaside in July 2014.
He has been prohibited from driving for two years, must pay a $2,000 fine and has a two-year probation under conditions including 200 hours of community service.
The community service is line with the victim impact statement from Georgia Walsh's mother, Jillian Walsh.
"You can right the wrong of a life taken way too soon by living your own life in a way that gives back to the community and to this country and to the people you love," she said in a statement representing the Walsh family.
"Live the full healthy life of two people, yours and Georgia's."
Stupar is suffering from post-traumatic stress disorder stemming from the incident, his lawyer said. Walsh's death has had a devastating effect on his life.
"Obviously this has ruined a number of lives. Nothing could be done here to change that," said Chris Morris, Stupar's lawyer. "Hopefully if people hear about this case, they will pay more attention when they drive and will be more careful."
The seven-year-old's death inspired a campaign around Toronto to drive more slowly in areas where children play.Suggest a correction
