The Inco strike of 1978 (locally referred to as the Sudbury Strike of 1978) was a strike by workers at Inco's operations in Sudbury, Ontario, which lasted from 15 September 1978 until 7 June 1979. It was the longest strike in Inco or Sudbury history until the strike of 2009–10, and at the time broke the record for the longest strike in Canada.[3] It has been noted as one of the most important labour disputes in Canadian history.[4]
