Two pedestrians in the GTA are dead, one after being hit by a car in Scarborough and another after being trapped under a bus in York Region. And a third is in serious condition.

The York accident happened first at about 4 p.m. The bus hit the woman in Vaughan on Pine Valley Drive between Embassy Drive and Langstaff Road on Thursday afternoon.

Emergency crews rushed to the scene and propped up the bus in an attempt to reach the victim.

However, paramedics were unable to save her. An air ambulance had been called to the scene, but was then called off.

The victim's age hasn't been confirmed yet, but there are unofficial reports she was in her mid-teens.

A few hours later, a car struck and killed a woman in her late 30s or early 40s as she crossed Birchmount Road at Rolark Drive, between Ellesmere Avenue and Highway 401. She was pinned beneath the vehicle.

Then shortly before 7 p.m., paramedics took a 52-year-old woman with serious head injuries to the trauma centre at Sunnybrook hospital.

That incident happened at Jane Street and Falstaff Avenue, which is just south of Highway 401.

Another non-fatal incident occurred in Thornhill when a York Regional Police cruiser on its way to a car was involved in a collision with a black SUV.

A total of five people were left injured in the incident, which occurred at Bathurst Street and Atkinson Avenue. That location is about one kilometre south of Highway 407.
