LiUNA Local 183

What LiUNA Local 183 does

LIUNA Local 183 is the largest construction local union in North America, representing over 70,000 members across Ontario in residential, industrial, commercial, institutional, infrastructure, restoration, formwork, and utility construction sectors. Founded in 1952 and affiliated with the Labourers' International Union of North America, the union delivers collective bargaining, grievance handling, and workforce representation on behalf of construction laborers, with employer counterparties spanning multiple contractor associations including TRCLB, DRCLB, MTABA, the Ontario Formwork Association, and provincial utility employers.

Its core service stack is delivered through affiliated operating units: a digital Member Portal (183m.ca) for dues payment, tax receipts, and virtual meetings; the LIUNA Local 183 Training Centre operating apprenticeship, construction skill, and health and safety programs at six Ontario sites; LIUNA Care 183 for employer-funded health and welfare benefits; the LIUNA Pension Fund of Central and Eastern Canada for retirement security; and the Labourers' Local 183 Scholarship Trust Fund, which has distributed over $10.5 million in scholarships since 2006. Distribution is anchored by a Toronto headquarters on Wilson Avenue, a newly opened Vaughan headquarters (May 2024), and regional offices in Cambridge, Barrie, Cobourg, and Kingston.

The union's revenue model is a recurring monthly dues subscription paid by individual members, supplemented by employer contributions that fund benefits and training; dues structure is not publicly disclosed. Member acquisition is community-led through organizing efforts and word-of-mouth across construction sites, and engagement is maintained via events such as Family Day at Downsview Park, an annual charity golf tournament, and active social media presence. As a member-governed nonprofit under the Ontario Labour Relations Act, the organization is controlled by its membership and led by an elected Executive Board headed by Business Manager Jack Oliveira.

Scale indicators6 records

Recent moves8 records

Expansion highlights5 records

Broad incumbents

• Labourers' International Union of North America (LIUNA): LIUNA is the parent international union and federation to which Local 183 belongs. As the broader North American labor federation covering hundreds of thousands of laborers across construction, waste management, and healthcare, it shares Local 183's core mission of collective bargaining and member services and represents the macro structure within which the local operates.
• Teamsters Canada: One of Canada's largest labor organizations, with significant construction, warehousing, and transportation membership. As a broad incumbent across multiple industries, Teamsters represents an alternative organizing destination for Ontario workers and competes for collective bargaining leverage with large employer groups.
• United Steelworkers (USW) Canada: A major Canadian private-sector union representing workers in construction, manufacturing, and resource industries. With overlapping construction membership and large-scale bargaining capacity, USW is a broad incumbent peer operating across similar labor-relations and collective bargaining domains in Canada.

Direct peers

• Carpenters' Regional Council (Ontario): Represents carpenters and related trades across Ontario's ICI and residential construction sectors. As a fellow Ontario construction union that negotiates provincial collective agreements with overlapping contractor associations, it directly competes with Local 183 for both members and contractor signatory relationships in the same GTA market.
• International Union of Operating Engineers Local 793: Represents Ontario operators of heavy equipment, cranes, and related construction machinery. As a fellow large Ontario construction union that collaborates (and competes) with Local 183 on joint advocacy — including the Skills Development Fund defense referenced in the data — it is a direct peer in the same provincial labor ecosystem.
• International Union of Painters and Allied Trades (IUPAT) District Council 46: Represents painters, glaziers, drywall finishers, and related trades in Ontario construction. Referenced as a Local 183 partner in the Walnut Foundation PSA blood testing program, IUPAT is a direct peer competing for the same Ontario construction labor pool and engaging in similar benefits and training initiatives.
• CLAC (Christian Labour Association of Canada): A multi-sector Canadian labor organization with significant construction membership across Ontario. Named as a peer stakeholder that jointly defended the Skills Development Fund alongside Local 183, CLAC represents an alternative labor model that competes for the same workers and contractors in Ontario's unionized construction market.
• International Association of Bridge, Structural, Ornamental and Reinforcing Ironworkers Local 721: Represents Ontario ironworkers on structural steel, reinforcing, and ornamental construction. As another Ontario-based construction trade union with its own apprenticeship, dispatch, and collective bargaining apparatus, it directly competes with Local 183 in the heavy structural and ICI construction segments.
• International Brotherhood of Electrical Workers (IBEW) - Ontario Construction Council: Represents electricians and communication technicians across Ontario's ICI and utility construction sectors. With overlapping utility-sector collective agreements (Local 183 also holds a Provincial Utility CBA), IBEW competes for the same skilled-trades workers and contractor relationships in Ontario.

Regional players

• LIUNA Local 506: Another Ontario-based LIUNA local covering construction laborers in a different geographic region (Hamilton-Niagara area). As a fellow LIUNA local with the same trade jurisdiction, Local 506 is a regional peer with comparable operations (training, dispatch, benefits) but a separate geographic footprint, illustrating how the LIUNA federation segments Ontario labor representation.
