Local 793 of the International Union of Operating Engineers represents thousands of crane and heavy equipment operators in Ontario’s construction industry.

We build the roads and bridges you travel on, the subways you ride in, and the offices you work in. We also build pipelines, stadiums, refineries, subdivisions, and work in landfills, mines and quarries.

Union members operate mobile cranes, tower cranes, concrete pumps, bulldozers, excavators, graders, tractor loader backhoes and many other types of heavy equipment.

IUOE Local 793 members have helped build Toronto’s key infrastructure and many of its landmarks, such as the CN Tower, the SkyDome (now Rogers Centre), and New City Hall, as well as residential and commercial buildings, subway lines, and hospitals.

Over the years, the membership of Local 793 has met every challenge, and continued to organize and press for positive change. The local has blazed a trail to bring dignity, safe working conditions and economic benefits to thousands of operators on construction sites across the province.

The story of Local 793 is one of hope, hard work, pride and perseverance.
While building on the foundations of the past, Local 793 is preparing for the challenges of the future.
