A Dairy Queen in Cole Harbour, N.S., was damaged in a fire early Sunday.

An RCMP officer driving by 1038 Cole Harbour Road spotted flames inside the drive-through window at about 1:15 a.m. and called for help.

Halifax Regional Fire Division Commander Corey Beales said it’s not clear if the fire started inside or outside.

“The place is going to be closed for quite some time,” he said. “They sustained significant fire, smoke and water damage.”

The restaurant was closed at the time and nobody was inside. Beales said a security company is guarding the site Sunday and fire investigators will arrive Monday.

“If the cause is suspicious, we will turn it over to police,” he said.

The Dairy Queen is in a small strip mall. Smoke may have spilled into other units and caused damage, Beales said.
