Two people were critically injured after a taxi and a transport truck collided in Brampton this morning.

The two-vehicle crash occurred near Dixie Road and Queen Street East at around 5:10 a.m.

Witnesses at the scene said it appeared as though the truck rear-ended the cab at a high rate of speed.

Peel Paramedics say two passengers in the back seat of the cab, identified as a man and a woman in their 40s, were rushed to a trauma centre with life-threatening injuries.

The driver of the taxi went to a local hospital with minor injuries and the transport truck driver was uninjured.

Roads are closed in the area as police investigate.
