NANAIMO — More than 50 people from a supportive-housing complex in Nanaimo, B.C., have been displaced after a fire in a mattress that was started by a cigarette.

Troy Libbus, Nanaimo Fire Rescue’s assistant chief, says their crew responded to an alarm Sunday at Samaritan Place, a supportive-housing complex that has 51 units.

He says no one was hurt, as firefighters were able to fight the blaze and evacuate residents at the same time, thanks to the building’s sprinkler system that helped suppress the fire.
