International Union Of Operating Engineers, Local 793

International Union Of Operating Engineers, Local 793 Local 793 represents thousands of crane and heavy equipment operators, and other skilled workers in At the end of that meeting, the men sent a letter to H.M.

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 campu

s 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. Richardson, J. 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.

Opportunity is knocking for members of Local 793 in northern Ontario as work officially gets underway on the first segment of the new road network to the Ring of Fire.
The $61.8 million Geraldton Main Street Rehabilitation Project will connect Hwy. 11 in the south with Hwy. 584 in the north and prepare the road to handle the heavy traffic expected to come with the opening of new mines in the mineral rich area located 500 km northeast of Thunder Bay.
The provincial government estimates the Ring of Fire redevelopment will create more than 70,000 jobs in industries across Ontario and generate over $22 billion dollars over 30 years. It says developing a network of all-season roads is a key step in the plan – music to ears of our members.
Local 793 Executive Board member and Northwest Ontario Area Supervisor John Kelly and Special Projects Representative Kyle Park were at Tuesday’s groundbreaking in the Municipality of Greenstone, where Minister of Northern Development and Minister of Indigenous Affairs in Ontario Greg Rickford announced, “The Ring of Fire is no longer a distant promise - it is happening now!”
Local 793 signatory contractors Pioneer Construction and Bélanger Construction will be working on the road improvement project.
With much of the proposed road network cutting through their land, much time has been spent in building partnerships with First Nations and other Northern communities, ensuring they share in the jobs and prosperity that will be created.
Chief Sonny Gagnon of Aroland First Nation spoke at the event of the importance of developing responsibly together with the government, with support also being offered by Chief Yvette Metansinine of Animbiigoo Zaagi’igan Anishinaabek.
Work on the road in Geraldton is expected to take three years.

OETIO has been awarded $400,000 by the government of Ontario to renovate the dome at the Morrisburg campus.
The funds, which were obtained through the Apprenticeship Capital Grant (ACG), will be used to replace the dome's cover and add internal electric lighting.
The renovation of the 400-by-135-foot structure, which was built in October 2009, will allow OETIO to continue providing programs year-round.
Operating Engineers Training Institute of Ontario was one of just six training providers to have its application for funding approved, with the ACG allocating a total of $1.75 million to support apprenticeship training projects.
Local 793 Business Manager Mike Gallagher said, “We are grateful to Premier Ford and Minister of Labour, Immigration, Training and Skills Development David Piccini for the award of $400,000 for the renovation of the dome in Morrisburg, which will ensure our apprentices continue to learn their trade in a safe and controlled environment whatever the weather.
“Having invested nearly $300 million in training over the past three decades and with a third training centre soon to open its gates near Barrie, Local 793 is pleased to have a partner in government that recognizes the importance of attracting more young people to the skilled trades and giving them the tools they need to succeed.”

A good mentor can often become a father figure to a young Operator taking their first steps in the trade. It just so happens that for Ethan Medeiros, his father is his mentor! Union Steward Donny Medeiros has been a member of Local 793 for two decades and is currently working for Hydro One on a transmission line upgrade project near Flamborough, where he works closely with his son Ethan, 21, who joined the Union just two years ago. It’s great to see our Union family continuing to grow!

Business Manager Mike Gallagher provides a video update for Local 793 members as the country heads into the Victoria Day long weekend.
It has been an incredibly productive spring for the Union, capped by the return visit of Prime Minister Mark Carney to Oakville at the end of April. He used the occasion to announce his Team Canada Strong measure, a $6 billion effort aimed at recruiting, training and hiring up to 100,000 Red Seal tradespeople in the next five years. You can read all about the PM's visit and the details of the government's investment on the IUOE Local 793 website.
Brother Gallagher also delivers more good news for members, including:
• the new training centre set to be completed later in the summer in Oro-Medonte
• the purchase of the property next door to our HQ which will help us train more Operators
• the promise of good jobs in the North
• the Union's expansion into the railroad sector - with 300 new members from A&B Rail coming over from LIUNA 183,
• a big jurisdictional dispute win recorded against the Labourers at the Ontario Labour Relations Board.
• Important information on the Pension and Benefits plans
If all that wasn't enough, it looks like the sun might even be making a comeback!
We wish you and your families a happy Victoria Day long weekend!
