Massive plumes of smoke hovered over parts of Montreal Saturday evening as a major blaze hit a mattress factory on Marco Polo in Riviere des Prairies.

About 100 firefighters were called to the scene of the blaze which blackened the sky near Ray Lawson and Henri Bourassa.

Nobody was hurt in the fire which started at about 5 p.m. Saturday. 

No cause or damage estimate was immediately made available by the Montreal fire department.
