Around 90 firefighters were called in to battle the flames, which were sparked just before 10:30 p.m. Sunday.
The three storey building houses four apartments and two businesses, including Benedict's restaurant. All of the building's occupants escaped unharmed, however two cats perished in the blaze, according to one resident.
Suzanne Léveillé was asleep in her apartment when she was awoken by the smoke alarm. Léveillé and her 22-year-old daughter made it out unharmed, but their apartment was destroyed.
"I've lost everything," Léveillé said Monday morning as workers tried to clean up some of the aftermath of the fire.
"I can't even find a pair of shoes."
Fire officials said the blaze started in the main floor ceiling.
However, the exact cause is not yet known.
