Firefighters were on the scene early this morning as a multi-alarm blaze tore through a historic neighbourhood in Mississauga, near Hurontario Street and Dundas Street East. 

The blaze started in a grocery store on the southeast corner of the busy intersection and quickly spread to other commercial units — buildings described by fire officials as the original site of Cooksville in the 1800s.

Three ladder units arrived as crews fought the blaze in the bitter cold. 

At their height, flames shot through the roof and out through Karachi Bazaar, a video rental business at the rear. A wall of one of the buildings collapsed. 

"It's honestly very devastating because we spend more time here than we do at our own home," said Salman Hasan of Karachi Bazaar, when speaking to CBC News on Thursday.

Hasan said that his family’s business had been in operation since 1997.

No injuries have been reported, though the large building at 28 Dundas St. E. is expected to be a total loss. 

As of the supper-hour, the cause of the fire remained unknown. Crews were removing debris, so that fire investigators could get a closer look at the scene.

Back in Toronto, fire crews also responded overnight to a two-alarm house fire near Bayview and Moore Avenues.
