In the second such incident in less than two days, a fire at a housing complex on Gordon Street in Guelph has left residents there homeless.

Officials continue to investigate what caused the fire, though they apparently do have an idea where the blaze may have started.

Firefighters and other emergency crews were initially called to the scene late Monday night and the building was evacuated.

Guelph Police Sgt. Doug Pflug says "A 20-year-old female did suffer smoke inhalation and minor injuries and was treated at the Guelph General Hospital."

Residents remain distraught. They have not yet been allowed back in and it remains unclear when they will be able to return to their homes.

Elizabeth Kent of Victim Services Wellington says "Well I think it's tough. Some of them will have lost quite a bit of their belongings, others will have fire damage to their belongings."

The fire comes just one day after a Sunday morning blaze at a rooming house on Paisley Road that killed one man and forced residents out.

Police have identified the man who died in that fire as 52-year-old Ian Bull. A preliminary investigation has determined the fire is not suspicious. The cause remains under investigation.

Pflug says "Right now we are investigating this fire as a single incident, bearing in mind that there was one on Paisley Road and we have had fires on the East end. It's too early to determine if any of these fires have been linked."

There are reports that the unit in the Gordon Street complex where the fire started didn't have hydro and candles may have been used for light and heat.

But police don't yet know how the fire started, "Right now it's too early in the investigation to deem this a suspicious fire as investigators are still on scene and conducting the preliminary investigation," Pflug says.

Meanwhile displaced residents, many of whom have been put up in a hotel for at least a night, are looking for a place to stay.

Kent says "We're hoping we can give them even just a little bit of money so that they get the things they need, their personal needs items, and maybe some clothing."
