Residents of a downtown Kitchener condo building were sent outside for a period of time Wednesday morning as firefighters dealt with a fire in a ground-floor unit.

Firefighters were called to the Kaufman Lofts at King and Victoria streets around 9:45 a.m.

“The fire was first observed by someone who was passing by on King Street, and (saw) flames coming out of the window,” said Doug Voisin, a platoon chief with the Kitchener Fire Department.

Voisin said that person then went into the building and activated a fire alarm.

Responding fire crews rescued a dog from inside the unit and brought the flames under control. No people were home at the time of the fire.

“There was a fair amount of damage to the interior,” Voisin said.

The cause of the fire remains under investigation. Damage is estimated at between $50,000 and $70,000.
