The 14-year-old deceased was killed when a handball net toppled onto him during a physical education class.
His parents and sister successfully sued the school board.
The jury awarded $100,000 to each parent and $50,000 to the sister for loss of guidance, care, and companionship under the Family Law Act.
The trial judge also awarded the plaintiffs solicitor-and-client costs.
The school board appealed the damages and costs.
The Court of Appeal upheld the parents' awards as high but within the accepted range, but reduced the sister's award to $25,000 as inordinately high.
The costs order was varied to party-and-party costs, as the plaintiffs' settlement offers did not comply with Rule 49.10.
