A boy has died after being struck by a Lakeshore West GO Train just west of Long Branch GO station.

Peel police say the child, believed to be either 12 or 13 years of age, was struck in the area of Alexandra Ave and Fourth Street in Mississauga around 2:45 p.m.

Investigators say early information suggests the boy and another young child were on some sort of motorized bike in the area before he was struck.

Const. Tyler Bell-Morena said the traffic signals were functioning and in working order with the arms down, lights flashing and audible tone at the time of the incident.

“All the information at this point, and understand that it’s preliminary and subject to change, but everything we have at this point is that the child went around the barrier and was struck by the train,” continued Bell-Morena.

“This is a horrible situation for the family involved and it would be remiss of me not to remind motorists in the area, especially during this time of March Break with a lot of kids out and about, [to be] mindful of your surroundings.”

GO Transit has begun to run service through the area, but delays are still possible.

Fourth Street is closed from Ogden Avenue to Alexandra while Alexandra is closed from Fourth Street to Lakeshore Road East.
