It is a tragic situation that a grieving south Etobicoke family is coping with tonight.

A three-year-old boy is dead and his older sister is in critical condition after they, along with their father, were struck by a vehicle near the busy Burnhamthorpe Rd. and The East Mall on early Tuesday.

Toronto Police say they were called shortly after 11 a.m. to Montebello Gardens for a collision involving two children and their father.

The children, the boy and girl about seven or eight, were crossing the road with their father who is also in hospital receiving treatment, explained Det. Brett Moore, of Traffic Services.

The driver of the SUV, reportedly an 82-year-old woman, remained at the scene and was later taken to hospital for checks.

The toddler had his vital signs absent when emergency crews arrived and did not survive, police said, while the girl suffered serious injuries and was rushed to Sick Kids hospital.

“It appears that the driver of the motor vehicle was making a turn onto The East Mall, and the family was crossing the street and we don’t know how that came to be — which direction they were crossing,” Moore said.

Investigators said anyone who witnessed the incident or has dash camera footage is asked to call police.

Officers were canvassing the area in search of video footage or witnesses of the horrific incident.

Roads in the area were closed and motorists advised to take alternate routes.

“We are going to be asking the local community, anyone who saw something, to come forward,” police said.
