International Union Of Operating Engineers, Local 793 👷 Representing over +20,000 Operating Engineers in Ontario & Nunavut
✊ United We Stand At the end of that meeting, the men sent a letter to H.M. Richardson, J.

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. We have a head office and training campus in Oakville, another training campus in Morrisburg and district offices around the province. Our story began on Dec. 11, 1919, when 11 very determined men gathered at the Elliott Hotel in downtown Toronto to discuss their future. Comerford in Chicago, Illinois, then general president of the International Union of Steam Engineers, requesting that he immediately grant a charter and supplies for a new hoisting engineers local to represent workers in Toronto. The charter members were Frank Dennis, Joseph Valin, James Hawkins, William Wells, J.S. Miller, Thomas Lahey, Dave McBlaine, Mat Clark, A. Wright and R.J. Elliott. The men got their charter and the local was on its way. The early days weren’t easy. There were times when the future of the union looked bleak. During the Depression, for example, the local dwindled to just a few hardy souls. Money was so tight that the union office was closed and the furniture sold. Meetings were held in members’ homes. The only big project on the go was the construction of Maple Leaf Gardens in Toronto. But dedication to the cause, plain old determination by the members, and a slight boom in the coal trade combined with aggressive organizing conducted at the Toronto docks helped save the union. By 1942, membership had soared to 120 members. After the Second World War, the local continued to grow as operating engineers were called on to build schools, hospitals, roads and institutional and commercial structures around the province. The 1950s saw membership grow to 1,400. By then, the local also had enough money to rent an office at 205 Church St. in Toronto. In the 1960s, union membership expanded with plenty of work on massive projects like Lester B. Pearson International Airport and the subway in Toronto. The head office on Church Street was torn down and replaced with a new one. Union offices were also opened in other areas. In the 1970s, the local negotiated its first-ever provincial collective agreement. A pension plan and life and health benefit plan were also introduced. Another milestone was reached when the local succeeded in getting the hoisting engineers trade formally recognized in Ontario. By the 1980s, membership had surpassed the 8,000 mark. The union moved into a new home at 30 Commercial Rd. in Toronto and opened a training site on 50 acres north of Stouffville. The early 1990s proved to be a tough period for the local. A recession resulted in projects being cancelled and many members didn’t work for five or six months. More dark clouds gathered when the local was put under international supervision after getting into financial trouble. But as in the past, the union survived. The problems were straightened out, the union got its financial house in order and members went to work on projects like Highway 407, steel plants in Hamilton and the casino in Windsor. The union also elected a new executive and officers to lead it into the future under the guidance of business manager Mike Gallagher. In 2005, the union moved into its present home, a 34,000-square-foot, state-of-the-art head office at 2245 Speers Rd. in Oakville. Today, with more than 17,000 members, Local 793 has established itself as one of the largest and most successful construction locals in Ontario. 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.

Local 793 Business Manager Mike Gallagher and President Dave Turple welcomed Oakville mayoral candidate Sean O'Meara to our head office on Monday, where he toured the training facilities, met our apprentices and visited the Memorial Garden.

Local 793 has endorsed O’Meara to lead Oakville in the October 26 election.

Brother Gallagher and President Turple told the stories of some of our members who lost their lives on the job and whose names appear on the memorial wall, the tragedies that continue to fuel the union’s fight to improve training and jobsite safety.

O’Meara was able to test his operating skills on our hi-tech training simulators and chatted with some of our crane apprentices and instructors, insisting that under his leadership Oakville will build the roads, bridges and infrastructure the town needs.

Local 793 Business Manager Mike Gallagher has celebrated the outcome of Monday’s referendum in Alberta, noting that our country – like our union – is always stronger together.

CBC is projecting that 76% of Albertans rejected the proposal to begin the separation process.

Brother Gallagher said, “A united Canada is a strong Canada. With this referendum behind us, it’s now time for the country to get on with job of improving the lives of everyone who calls Canada home.

“With the U.S. president threatening to make Canada the “51st state” and then imposing sanctions that harm all of us, now was not the time for separatists to drag us down this dead-end road. In current circumstances, the separatist leaders’ secret meetings in Washington with American officials can be viewed as at best selfish and at worst treasonous.

“This result clearly shows that the push for a referendum was always more about United Conservative Party internal politics than any real desire by Albertans to split from Canada.”

The Business Manager, visiting Washington this week in his role as International Vice President, also bemoaned the high cost of the exercise, which some estimates have placed at $134 million.

He said, “It has been a colossal waste of money, not just in direct costs but in lost investment. If that money had instead been applied to issues that really matter, such as tackling homelessness, we would be a stronger country with far fewer Canadians suffering.

“We must now turn our attention to cross-country cooperation on things such as pipelines, infrastructure and workforce development so we can build up the economy, tackle real societal problems and make our great country even better.”

The 69th Annual Ontario Building Trades Convention took place this week in Ottawa, bringing together union leaders, industry stakeholders and government officials.

Business Manager Mike Gallagher led the Local 793 delegation in the capital, which included President Dave Turple, Vice President Mike Scott, Recording-Corresponding Secretary Steve Booze, Treasurer and OETIO Executive Director Rick Kerr, and Financial Secretary and Director of Health and Safety Brian Alexander.

During the conference, which was focused on worker safety, construction industry outlooks and ways to invest in skilled workers, Business Manager Gallagher addressed the board to emphasize that with a strong demand for labour and a shortage of workers, the priorities should be addressing Labour Board delays, improving health and safety, and retaining qualified workers in the building trades rather than asking workers to accept less.

Ontario Premier Doug Ford used the event to reiterate his government's backing of the skilled trades, touting its $2.5-billion investment in the Skills Development Fund and ongoing support of apprenticeships, which it says has delivered 14,000 new registrations and 9,100 apprenticeship completions in 2026.

There was more good news for training providers such as the Operating Engineers Institute of Ontario (OETIO) and workers wanting to build a career in the trades, as Federal Secretary of State (Labour) John Zerucelli announced on Thursday more than $430 million over five years to expand union training facilities, modernize equipment and support apprenticeship programs.

The government of Canada has announced more than $430 million in new funding over the next five years for the Union Training and Innovation Program (UTIP).

The investment is designed to allow union training providers such as the Operating Engineers Training Institute of Ontario (OETIO) to build new facilities, purchase equipment and improve access to and quality of training.

Speaking at the 69th Annual Ontario Building Trades Convention in Ottawa, John Zerucelli, Secretary of State (Labour), said the new funds will help Canada attract more people to a sector that is projected to have 1.4 million job openings in the decade up to 2033.

Local 793 is currently in the early stages of building a new regional office and training centre in Stoney Creek and has plans to develop further hubs in Sarina and Sudbury.

Last month, Local 793 Business Manager Mike Gallagher hosted Zerucelli at our new state-of-the-art training campus in Oro-Medonte, where he told the Secretary of State that with the right government support the union could build the three new facilities in two years instead of five.
