Emergency crews were called to a fire at Winnipeg's Mission Industrial Park on Thursday.

Bales and pallets of packed cardboard were ignited at Industrial Metals in the 500 block of Messier Street and the flamed began to quickly spread.

The building, which had about 20 employees inside, was evacuated.

No one was hurt.

Most of the bales in the compound were pulled out and hosed down.

Damage is estimated at $5,000.

The cause of the fire is under investigation.
