The Ottawa police’s arson unit is investigating a fire at a luxury condo construction site in Ottawa’s Little Italy neighbourhood Monday morning.

Ottawa fire officials said they were called to 115 Champagne Avenue South around 4:30 a.m. Monday when a passerby noticed a trailer on fire.

A 180-kilogram propane tank had to be kept cool by fire crews as the trailer fire was extinguished.

Fire officials said the case is being considered suspicious because there are signs of forced entry to the site of the future Soho Champagne condominiums.

Damage is estimated at $100,000 to the trailer and $50,000 to its contents.

There are no reports of injuries.
