One person has been rushed to hospital with critical injuries after a shooting in Mississauga.

Peel regional police say the incident happened outside a home on Acorn Place, near Hurontario Street and Highway 403, shortly after noon.

Police said the victim had “obvious signs of trauma” when officers arrived.

The victim, believed to be in his 20s, suffered a single gunshot wound, Peel paramedics said. He was transported to a Toronto hospital's trauma centre for treatment.

Investigators say they are looking for three male suspects who were travelling in a newer-model dark grey Chevrolet Malibu sedan with tinted windows and a large sunroof. Officers remain in the area canvassing for surveillance camera footage.

Residents in the area heard multiple gunshots ring out in the early afternoon. They say they're concerned for their safey in the area, which has seen two other shootings in less than a year.

"It's just scary. This needs to stop," said one woman, who wished to remain anonymous. "I have a son here... We could be walking or driving. This is really scary."

Acorn Place was closed at Ellia Avenue while police conduct an investigation.
