I had the honour of submitting the application for a Heritage Toronto plaque commemorating the history of the International Union of Operating Engineers Local 793, which was unveilled on November 4. The plaque is located on the Southeast intersection of Church and Shuter streets, where the Elliot House Hotel was once located and eleven steam shovel operators founded Local 793. This plaque is one of the outputs of the Laborem Ex Machina public history project that I am leading at York University.
