Canton's police chief says there were things out of the ordinary at the scene of Sunday's fire at a village landmark.
Chief James Santimaw declined to elaborate, but did say police are trying to determine if the blaze at the Dairy Queen is suspicious.
He said evidence has been sent to the state police crime lab in Albany.
The Dairy Queen at 45 Gouverneur Street was destroyed early Sunday morning, forcing the closure of Route 11 to close for about 8 hours.
The restaurant had been a fixture in Canton for 51 years and employed 15 people.
The property is owned by Gail Crabtree and John Putman. Putman's daughter, Jessica, told 7 News the family hopes to rebuild, but is waiting to see what insurance will cover.
At least 10 fire departments battled the blaze Sunday.
