Firefighters rescue 6 after suspected arson

Six people were rescued from an Ottawa highrise apartment building Sunday evening after a suspected arson.

Multiple 911 callers reported flames on the 13th floor of the approximately 15-floor building at 2850 Cedarwood Drive, which is in the south Ottawa neighbourhood of Herongate, just after 7 p.m.

When firefighters arrived they found a fire in the hallway and knocked it down by 7:30. As firefighters were battling the blaze, the six residents from three apartments went to their balconies to escape the fire.

All other residents had escaped the building but firefighters were forced to rescue the six who were stuck. They were brought to safety uninjured.

Damage to the building is about $300,000 and a fire investigator continues to examine exactly how the fire was set, but it was ignited intentionally, officials believe.

Most of the residents returned to their homes but the 13th floor remained abandoned Monday morning as walls and floors are charred, the CBC's Amanda Pfeffer reports.

Cedarwood Drive was closed for a couple hours but reopened around 9 p.m. Sunday.
