A vacant and boarded-up two-storey building on Clarence Street in the ByWard Market was destroyed by fire Wednesday morning, and the Ottawa police arson unit has been called in to investigate.

The flames broke out at about 4:15 a.m. at 211 Clarence St., near Cumberland Street, an abandoned home nestled between two six-storey apartment buildings.

One firefighter suffered a minor injury and was treated by paramedics, the fire department said. No other injuries were reported.

More than 100 firefighters brought the fire under control from outside the building because it was unsafe to enter. The building was destroyed.

"We'll probably end up tearing it down," said Ottawa fire department platoon chief Jom Cockran. "It's just a hazard right now."

Jamine Ackert, who lives nearby on Clarence Street, says she wrote to Coun. Mathieu Fleury with her concerns about the boarded-up house that burned down.

"I'd like to see a plan for swift development," Ackert said as she surveyed the scene Wednesday morning. "I have a daughter who goes to school here. Having more and more abandoned buildings is unsightly, it's frustrating."

Ackert said 211 Clarence St. was just one of several similar vacant homes in the vicinity.

Clarence Street is closed between King Edward Avenue and Dalhousie Street. Cumberland Street, which was closed between Murray and York streets, is now open.

Motorists and pedestrians are asked to avoid the area.

An Ottawa fire department investigator is at the scene and the Ottawa police arson unit has been called in to investigate.
