A fire tore through an unoccupied rooming house at 292 Lyon St. N. late last night.
Fire crews extinguished the flames after a second alarm was called to bring in more fighters to protect neighbouring homes.
No one was hurt.
The cause of the fire is under investigation. It has been deemed suspicious.
On March 18, two men were rescued from the rooftop of the two-and-a-half storey residence after a fire started in one of the units.
