The Battle of Ballantyne Pier occurred in Ballantyne Pier during a docker's strike in Vancouver, British Columbia, in June 1935. The strike can be traced back to 1912 when the International Longshoremen's Association (ILA), began organizing the waterfront workers in Canada, alongside the Lumber Handlers' Union in Vancouver. Going head to head with the employers association, the Shipping Federation, several strikes resulting in wage increases were won by workers in the coming years. Victories on the waterfront increased over the next decade, and by 1923, the Shipping Federation became determined to break the power of the ILA.
