An investigation is beginning into a three-alarm blaze at a two-story townhouse in the city's Corktown neighbourhood that broke out on Thursday evening around 8:30 p.m. 

The fire shut down Queen Street East in both directions from Power Street to River Street. The road has now partially reopened. 

The fire, which was brought under control by 11:30 p.m., initially posed some challenges to firefighters. 

"Due to how the fire is extending our crews are fighting the flames defensively, which means they aren't able to go in because of how heavy the smoke and blaze is," said Toronto Fire Captain Adrian Rathushniak on Thursday evening.

One firefighter was treated for a leg injury they sustained while responding to the blaze, according to Toronto paramedics. There were no other injuries. 

Buildings near the townhouse were cleared by crews, with residents allowed to return to their homes at about midnight, Rathushniak added. 

Toronto Fire says they will keep a crew throughout the day at the site as an investigation into the fire's causes gets underway. The presence of the fire truck will likely mean one lane on Queen Street East remains closed in that area, said Ratushniak. 

The Fire Marshall's Office will also be participating in the investigation due to the severity of the damage to the building.
