The 2006 Toronto Transit Commission wildcat strike was an illegal strike in Toronto, Ontario, Canada, on May 29, 2006. It was initiated by 800 Toronto Transit Commission mechanical and janitorial workers who were protesting proposed changes in work schedules, including permanent reassignment of 100 workers to night shifts.The strike began between 4 a.m. and 5 a.m. EDT, and quickly resulted in a large scale disruption of service when transit drivers honoured the picket line, effectively shutting down the Toronto transit system. The shutdown left over a million commuters searching for alternative means of transport.
