Dundas-Ossington blaze injures firefighter

A Toronto firefighter suffered minor injuries Wednesday morning while battling a blaze at College Street West and Ossington Avenue.

Fire crews were responding to a roof fire at an unoccupied building under renovation at 842 College Street.

The building is a two-storey century-old building that was undergoing renovations, fire officials said. The main floor was formerly a restaurant with two vacant residential apartments above.

The firefighter couldn't see due to heavy smoke and fell through a hole in the floor that had been cut by contractors.

He was taken to Toronto Western Hospital, but only suffered minor injuries, CBC's Trevor Dunn reported from the scene.

It was a two-alarm blaze, with 12 fire trucks and 45 firefighters responding.

Firefighters had the blaze under control quickly. The fire caused traffic backups in the area but TTC vehicles were moving through by 8:30 a.m.
