A man is dead, and three others have been injured after a two-vehicle collision in Scarborough Sunday evening.

Emergency crews were called to the intersection of Lawrence Avenue East and McMillan Avenue just after 6 p.m.

Sgt. Orang Momeni from Traffic Services said an Audi was travelling west on Lawrence Avenue at a high rate of speed when it lost control and entered the eastbound lanes, colliding with a white Jeep.

As a result, the Audi split into two pieces, Momeni said.

Scarborough collision

Images sent by a viewer show the front half of the vehicle lying on the north side of the road. The other half is resting across the street on the lawn of a residence.

A few metres away, the other vehicle is seen sitting on the sidewalk with extensive front-end damage.

"From video footage that we're able to view, it appears that this (Audi) was passing others at a very high rate of speed," Momeni said.

"You have a large debris field. And that alone shows you that the speed that was involved here was very high."

Momeni said there was nobody on the sidewalks at the time of the collision.

He said a passenger of the Audi, a man in his 20s, was pronounced dead at the scene.

The male driver of the Audi and the female driver of the Jeep were rushed to trauma centre in serious condition, Momeni said.

Another passenger of the Audi was taken to a local hospital with minor injuries.

Crash

"The investigation is still ongoing, and we are trying to gather as much information as possible," Momeni said.

Suman Mohindra, who lives a few blocks away, said she came running out of her house after she heard a "big bang," something she's never heard in her life.

Mohindra said when she reached the crash site, she saw paramedics trying to revive one person lying on the road.

"This is a quiet street. And I find it sometimes because it's a quiet street some people do speed up," Mohindra's husband Bal said.

Momeni said the speed limit on this section of Lawrence Avenue East is 50 km/hr.

Police have closed Lawrence Ave East from Morning Dew Road to Beechgrove Drive for the investigation.

"We are hoping that anybody who might've seen this or might've captured this on a dashcam would contact us at Traffic Services and help us with the investigation," Momeni said.
