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.
Vancouver Island Coal Strike began on 16 Sept 1912 when miners at Cumberland declared a "holiday" to protest the firing of Oscar Mottishaw. Canadian Collieries, recent purchaser of the Dunsmuir Mines, locked them out and hired Chinese and recruits from Britain and the US as strikebreakers.
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.
