The Oshawa man accused in the death of a 35-year-old father of three in a collision after which he fled the scene has plead guilty to multiple charges.Jaiwin Kirubananthan appeared in a Newmarket court on Monday morning and entered a guilty plea for dangerous driving causing death, three counts of dangerous driving causing bodily harm and fail to remain where death ensued. Kirubananthan was 18 at the time of the incident.Andrew Cristillo was killed in a crash between two vehicles on Highway 48, between St. John Sideroad and Ballantrae Commons on August 3, 2025. His three daughters, all under the age of eight at the time, suffered life-altering injuries. His wife Christina, who has been battling breast cancer for the past few years, was also injured.According to the OPP, the driver of the second vehicle fled the scene but was found shortly afterward and arrested. They also confirmed to CityNews that the accused was also involved in another crash back in January, 2025 which involved an OPP vehicle that was driving Premier Doug Ford. Kirubananthan was charged with dangerous driving in that incident as well.Following Cristillo’s death, his family launched a petition to urge the Ontario government to strengthen dangerous driving laws. The petition has garnered more than 43,000 signatures so far.Ontario premier Doug Ford met with Cristillo’s family last summer and pledged to bring forward legislation in response to the family’s petition.The legislation, called dubbed Andrew’s Law, was tabled in November and if passed, it would enact lifetime driving bans for those convicted of dangerous driving causing death.The new law would also allow police to immediately suspend a driver’s licence for 90 days if they have reason to believe someone is driving dangerously, and impose increased fines.The legislation is currently making its way through Queen’s Park and is in the second reading stage.Speaking to media outside the courthouse, Cristillo’s younger brother Jordan said passing the law is “common sense.”“If you can’t be trusted behind the wheel, you shouldn’t be back behind the wheel,” he said. “When people are going over 200 kilometres an hour, hitting the premier of Ontario’s car and back behind the wheel in 30 days, clearly out system is failing us and it failed my brother.”Jordan, along with family and supporters, gathered at the courthouse holding signs that read “Justice for Andrew = prison for Jaiwan.” As the trial got underway, Jordan made another appeal to lawmakers to pass the law as soon as possible.“This crime – dangerous driving causing death – goes up to a lifetime in prison. However too often our sentences favour the criminals and not the victims and sympathy for the criminals is cruelty to the victims. We want to see a change to that starting today,” he said.He asked for both justice to be served as well as lasting change to ensure no other family has to suffer through the grief they’ve had to face.“Nothing’s going to bring my brother back, we understand that. Justice means a couple of things to us. One is that we prevent future tragedies like what happened to Andrew from happening to someone else, so that his legacy becomes one of protection. And two that the individual that caused this is made an example of. Why? Because this crime wasn’t an accident. As Doug Ford said, it was murder.”More to comeWith files from Afua Baah and The Canadian Press
