A multi-vehicle crash has left one person dead, four others injured and has closed the westbound lanes of the Gardiner Expressway.

Toronto police and fire are on the scene of the fiery collision that happened just after 5:30 Tuesday evening to reports of several vehicles on fire.

At least five vehicles were involved and three of them caught fire, but the blaze has been put out by firefighters.

Acting Insp. Phil Sinclair confirmed one person was pronounced dead on the scene while four others were taken to hospital with injuries, varying from minor to serious.

All the people involved were adults, but no further details have been released.

The events that led to the collision are still under investigation.

All westbound traffic is being forced off at the Yonge/York Street exit and the westbound Gardiner is closed from the Don Valley Parkway to Jarvis Street. The southbound DVP is closed from Richmond Street to the Gardiner.

The closure is expected to last several hours.
