Two children were seriously injured after two separate collisions in Mississauga Sunday night.

Peel Regional Police say the first collision happened in the area of Eglinton Ave. and Ninth Line just before 7 p.m., when a 7-year-old girl was struck by a vehicle.

The girl was taken to a Toronto hospital with serious, but non-life-threatening injuries. Peel Police Const. Akhil Mooken told the Star Monday morning that the girl is now recovering and in stable condition.

Police say the driver remained at the scene.

Around 9:45 p.m., police tweeted that a 4-year-old boy and a woman were hit by a vehicle near Goreway Dr. and Morning Star Dr.

The child was taken to hospital with life-threatening injuries. Mooken said as of Monday morning that he is now in stable condition.

The woman was also taken to hospital.

Police have closed Goreway Dr. between Morning Star Dr. and Etude Dr. for investigation. Mooken said there were many people celebrating Canada Day in a nearby plaza that could have potentially witnessed the incident.

Police are asking anyone with information on either collision to contact the Major Collision Bureau at (905) 453-2121, ext. 3710. Anonymous information may also be submitted by calling Peel Crime Stoppers at 1-800-222-8477.
