Two volunteer firefighters died while trying to put out a blaze at a store in Listowel, Ont., Thursday, provincial police say.

The firefighters went missing a short time after the fire broke out at a Dollar Store. Police later found their bodies inside the building.

"A search of the structure revealed that two firefighters had succumbed to injuries sustained while fighting the fire," Ontario Provincial Police said in a press statement.

Police have not yet identified the firefighters.

Listowel is located about 150 kilometres west of Toronto.
