DORVAL -- Two people are dead and several others injured after a violent collision involving an STM municipal bus in Dorval.

The incident took place at the intersection of 55th Ave. and Lindsay Ave., where the impact of the crash was enough to flip the 196 city bus on its side onto the lawn of a commercial business.

One of the victims was the 61-year-old female passenger of a BMW. The second was the bus driver, a man in his 50s.

The driver's body was trapped under the bus, which had to be righted by emergency crews in order to extract him from the wreckage.

"This is a great day of mourning for us and our thoughts go out to the family of course," said STM spokesperson Marianne Rouette, adding that the STM would conduct its own investigation into the incident.

Two other people suffered very serious head injuries and were in serious condition, including the female driver of the BMW and a passenger on the bus. Both are expected to survive.
Five people were taken to hospital to be treated for relatively minor injuries. Four other people were treated on the scene by emergency crews, but chose not to be transported to hospital.

Reconstruction experts were on the scene for hours Tuesday night, trying to determine the cause of the crash.

The collision took place at about 6 p.m., during rush hour, in an industrial park.

"According to information provided by witnesses, the bus was travelling on Lindsay Ave. westbound and the other vehicle was going north on 55th Ave. The collision occurred at the corner of two streets," said Montreal police spokesperson Jean-Pierre Brabant.

"The second car, a Mazda 3, was on the corner, facing south on 55th Ave. The two passengers (in that car) were not injured."

Immediately following the incident, the site was described as chaotic, with scores of ambulances rushing to assist the victims along with other emergency vehicles. The road was closed to traffic.

Two smashed cars lay near the flipped bus. On one car, the impact was so hard that the engine block was pushed inside the vehicle.

"It was clearly a major impact," said Bob Lamle, spokesman for the city ambulance service. "The vehicles have major frontal damage and the first car, the front end is almost cut off."

There were about 14 people riding on the bus at the time of the deadly collision.
