Several families are temporarily homeless following a fire that raged through a Brampton townhouse complex overnight, causing an estimated $2.4 million in damages, fire officials say.

Firefighters spent more than five hours trying to douse the flames at 3 Darras Ct. where eight units were engulfed after the blaze broke out Saturday around 9:50 p.m., according to Peel police.

The fire spread through the upper levels of the townhouses, moving through the roofs, a Brampton fire spokesman said.

None of the 14 displaced tenants were injured in the fire near Clark Boulevard and Bramalea Road. Two firefighters sustained minor injuries, Platoon Chief Ed Davis said.

No sign of arson

A small crowd of residents gathered outside the building. One woman was holding her hand over her face as she watched firefighters try to extinguish the flames. Smoke poured out of the building's roof as red and blue flashing emergency lights reflected off the haze.

Brampton's Emergency Measures Office has begun helping the displaced families find shelter, according to a tweet from fire officials early Sunday.

Others affected are staying with family.

The fire's cause has yet to be determined, but a police spokeswoman said she does not believe it was set deliberately.

The Ontario Fire Marshal continued to investigate the incident Sunday.
