Explosions flattened a fireworks factory near Montreal early Thursday, with noise from the blasts heard and seen from several miles away, police said.
Fireworks could still be seen exploding in the smoke billowing from the warehouse in Coteau-du-lac, Quebec, 50 kilometers (31 miles) southwest of Montreal, for several hours after the initial blast at about 9 am local time (1300 GMT), according to television images.
Authorities said they will be unable to determine what caused the explosions until it is safe to approach the demolished factory to investigate.
No injuries were reported, but dozens of people were evacuated from nearby homes and a campground as a precaution.
A highway connecting Montreal and Toronto was also closed, as was a train line linking Montreal to Ottawa.
