I know about a lawsuit being reported by The Toronto Star two-three years ago. It was about a teenaged boy in St. Catherines, ON. The teenager had bought a bike from Canadian Tire, that had some defect in it. While riding the bike one day, he slammed it against something and lost a few teeth, and incurred some permanent disability, and disfigurement. Canadian Tire fought the family tooth and nail but a local court did award them some sizeable compensation (in real money, not Canadian Tire money). May be, someone in St. Catherines will post more details.
