On 10 March 1957, the 1,000 workers of Gaspé Copper Mines in Murdochville, Québec, struck for the right to unionize. The conflict lasted 7 months and ended in defeat for the miners. Moreover, a 15-year judicial battle finally awarded the company $1.5 million in damages from the United Steelworkers of America ("Métallos" in Québec).
The Winnipeg General Strike, 15 May-25 June 1919, is Canada's best-known general strike. Massive unemployment and inflation, the success of the Russian Revolution in 1917, and rising Revolutionary Industrial Unionism all contributed to the postwar labour unrest that fuelled the landmark strike.
Two days later, the 3 main UNION CENTRALS defied a municipal ban to organize a huge march in solidarity with the newspaper workers. More than 12 000 people clashed with 100 Montréal policemen. The outcome was some 50 arrests, several dozen injuries and one death from natural causes.
