The Appeal Court says the amounts may have been high but were still reasonable.
The case involved the death of 30-year-old Michelle Vokes, who was killed when her minivan was demolished by a car driven by Randy Palmer six years ago in Owen Sound, Ontario.
Palmer was driving as fast as 120 kilometres an hour in a 50 zone when he slammed into Vokes.
The awards of $135,000 to the then-three-year-old daughter and $1117,000 to the then-five-year-old daughter $117,000 for the loss of care, guidance and companionship of their mother set new benchmarks. The previous high award to a child who lost a parent in Ontario, $65,000, was awarded in 2011.
