When Montreal's police force went on strike for one day over pay in 1969, there was looting and rioting in the streets. But the city's problems leading to the unrest had been building for more than a decade. Organised crime, militant separatists and commercial rivalries all erupted on 7th October, just as police officers decided to protest that their pay was much lower than officers in other Canadian cities. Sidney Margles was a local reporter, and described the scene, and the underlying problems, to Rebecca Kesby.
