Four people were rushed to the hospital — two with life-threatening injuries — Thursday night after Peel police responded to two separate collisions in Brampton.

At around 9:50 p.m., investigators rushed to the Chinguacousy Rd. and Queen St. area after they received a call for a two-vehicle collision.

One of the vehicles struck a barrier and flipped over, investigators said. The driver of the vehicle was rushed to the hospital in critical condition while two other people were transported to hospital in stable condition, paramedics said.

Two hours later, Peel police said they responded to another call for a two-vehicle collision in the Goreway Dr. and Castlemore Rd. area.

Investigators said a dump truck and a minivan collided.

According to paramedics, the male driver of the minivan was transported to the trauma centre in life-threatening condition.

Police are investigating the cause of both incidents.
