Dale was driving 40 kilometres per hour (kph) in a 40 kph zone down the right-hand lane of a fourlane Ontario street where children were playing. Nine-year-old Patrick ran into the street chasing a soccer ball. Dale, without glancing over his left shoulder or looking in his rear-view mirror as prescribed by traffic regulations, swerved into the other lane to avoid Patrick. In so doing, he hit a car driven by Danika and going in the same direction as Dale in the left-hand lane at 50 kph. Danika lost control of the car, hit a utility pole, and was seriously injured. The pole, owned by Powerco, snapped in two and the wires were about to fall on Patrick, still in the street. Paula, standing nearby, saw this and ran to push Patrick out of harm's way. She succeeded, but in saving Patrick was hit by the wires herself. Paula died of electrocution and burns from the wires. Patrick survived with some bruises and scraped knees.
