Peel Regional Police have released the names of three people who were killed and three people who were injured in a crash in Mississauga on Sunday night.

The crash involving two silver vehicles occurred on Winston Churchill Boulevard, north of Queen Elizabeth Way, at about 11 p.m.

Canville Roberts, 40, a Mississauga man and the driver of the first vehicle, died at the scene. Five-year-old Ayon Brown and 13-year-old Keziah Edwards-Young, passengers in the second vehicle, died in hospital.

Police said Roberts was driving a Mazda 6 southbound on Winston Churchill Boulevard when he lost control for unknown reasons, crossed the centre median and crashed into a northbound Mercedes C250.

The crash left both cars demolished. (Tony Smyth/CBC) One of the cars was turned into a twisted pile of metal and police say speed may be a factor in the crash.

Camall Brown-Williams, 24, the driver of the Mercedes and Ayon's father, suffered non-life threatening injuries in the crash.

Also injured was Lekeisha Edwards-Smith, 25, a passenger in the Mercedes and Keziah's sister. She remains in a Toronto hospital in critical condition.

Ayon Brown is the son of Camall Brown-Williams and Lekeisha Edwards-Smith, police said.

Jynnai Hartley, 7, a passenger in the Mercedes and the god-daughter of Lekeisha Edwards-Smith, was taken to a Toronto hospital, where she remains in stable condition.

Police are appealing for witnesses who may have seen the crash, have dashboard video footage, or who may have information about the drivers prior to the crash.
