Two fatal traffic accidents occurred on Ontario's Highway 400 within a few hours of each other, beginning around 11 p.m. on Aug. 6 when a motorcyclist died in a single-vehicle crash. Around 4 a.m. the following day, an 82-year-old Vaughan woman was struck and killed by an apparent hit-and-run driver.
Following the motorcycle accident, the southbound lanes of Highway 400 were closed for several hours in the vicinity of Highway 401. The hit-and-run pedestrian accident caused lane closures for about five hours. One constable stated that even the alternate routes were congested and that it would take some time for traffic to clear.
