 While mailboxes, particularly in the affluent and predominantly Anglophone city of Westmount, were common targets, the largest single bombing was of the Montreal Stock Exchange on February 13, 1969, which caused extensive damage and injured 27 people.Other targets included Montreal City Hall, Royal Canadian Mounted Police, armed forces recruiting offices, railway tracks, and army installations.FLQ members, in a strategic move, had stolen several tons of dynamite from military and industrial sites, and, financed by bank robberies, they threatened through their official communication organ, known as "La Cognée", that more attacks were to come.
