The Treaty Three Police and the Ontario Fire Marshall's Office is investigating a fire near Devil's Gap that destroyed seven cottages.
Fire Chief Warren Brinkman says they know which cabin the blaze started at, and because the units are so close together, it didn't take long for the fire to spread.
He says their main priority became to protect a large lodge nearby.
Crews spent several hours putting out the fire and didn't leave the scene until about noon on Saturday.
