A pair of fires, one in Point St. Charles and another on the Main, caused untold damage Wednesday but no injuries were reported.

The first fire burst out at a building on the Main during the noon hour, leading firefighters to ascend to the roof to battle the flames at about 12:15 p.m.

No injuries were reported at the four-storey, 50-year-old building at 3780 St. Laurent, just north of Pine Ave.

Police were initially asked to investigate the possibility of arson but later Wednesday a police representative told CTV Montreal that the fire is believed to have started in a stove.

Later Wednesday huge plumes of smoke filled the sky above a vacant industrial structure on Le Ber street in Point St. Charles at about 8 p.m. 

Firefighters attacked the blaze on the roof of the industrial structure at 1830 Le Ber while police set up a perimeter. The structure will likely have to be demolished. Arson is not suspected.
