TORONTO -- Three teenagers and two adults were injured after a three-vehicle collision in Scarborough Tuesday afternoon.

Emergency crews were called to the area of Pharmacy Avenue and Donside Drive around 3:55 p.m. after receiving a report of a crash.

According to Toronto police, emergency personnel had to rescue a “young female” who was trapped in a vehicle. She sustained serious injuries and was transported to a trauma centre.

Paramedics said that two teenage girls and a “young male” were seriously injured and transported to SickKids Hospital for treatment.

A woman believed to be in her 50s was also transported to a trauma centre with serious injuries. A man believed to be in his 40s sustained minor injuries, paramedics said.

Toronto police Sgt. Neil Munroetold CP24 Tuesday evening that a white Infiniti vehicle had crossed into the southbound lanes and struck two smaller cars head-on.

“We are very early into the investigation so it’s going to be a while until we determine exactly how this occurred,” he said.

Investigators spent most of the day canvassing the area in search of witnesses and video footage of the incident.

Roads in the area were closed while police investigate the incident.
