An explosion at a semi-detached home in Brampton that seriously injured a one-year-old child was caused by an exploding alcohol still, police say.

A man has now been charged over the explosion, which occurred around 1:30 p.m. on Tuesday near Humberwest Parkway and Cottrelle Boulevard.

Aerial footage from the scene showed severe damage to the back of the home.

The injured child was taken from the scene to a local hospital for treatment for second-degree burns.

A 57-year-old man from Brampton has been charged with arson by negligence. He was released a promise to appear and is scheduled to appear in a Brampton court at a later date.
