Brandon Pardi has lost his bid to have his verdict and sentence overturned.
Pardi, now 24, was convicted of dangerous driving in the Halloween 2007 death of 3-year-old Bianca Leduc in Ile Perrot.
He had just turned 18 when the car he was driving crashed into Bianca's babysitter's backyard — as they were putting up Halloween decorations.
In 2012, Pardi was sentenced to two years less a day to be served in the community.
Today, the Quebec Court of Appeal has upheld the guilty verdict, and the sentence.
Pardi's lawyers had tried to argue — unsuccessfully, in the end — that Pardi should have been tried as a youth, since the crime happened on his very first day as an adult.
