No local stands alone.

Sheet Metal Workers' & Roofers' Local 235 is an affiliate of the Essex & Kent Building Trades Council in Windsor, which describes itself as an affiliation of fourteen local trade unions representing over 12,000 trades professionals across Essex and Kent Counties. The Council lists the local among its affiliates as Sheet Metal Workers and Roofers.

Being one of fourteen is what makes a union jobsite work. The trade beside you is held to the same training and safety standard, and the trades speak together on procurement, project agreements and safety law rather than one local at a time.

Local 235 also services the Sarnia area, where the Sarnia-Lambton Building Trades Council represents the building trades. Provincially the councils coordinate through the Provincial Building and Construction Trades Council of Ontario, and nationally through Canada's Building Trades Unions.

Local 235 is a chartered affiliate of SMART, the International Association of Sheet Metal, Air, Rail and Transportation Workers, which represents skilled workers across construction, manufacturing, service, railroad and shipyard industries in Canada and the United States.

Provincially the local sits within the OSMWRC, the Ontario Sheet Metal Workers' & Roofers' Conference, which coordinates the Ontario sheet metal and roofing locals. Wage schedules for Local 235 members are negotiated provincially through the Conference.

Members work under the Local 235 Collective Bargaining Agreement, which sets the terms and conditions of employment across the local's four trade classifications: Sheet Metal, Roofing, Decking & Siding, and Air Balancing. Apprentices work under the same agreement from their first day on the job.

On the employer side the provincial sheet metal agreement is bargained with the Ontario Sheet Metal Contractors' Association. Apprenticeship and trade certification in Ontario are administered by Skilled Trades Ontario, and employment standards, health and safety law and labour relations sit with the Ontario Ministry of Labour, Immigration, Training and Skills Development.

Sheet Metal Worker is a compulsory certified trade in Ontario under trade code 308A, so the work requires a valid Certificate of Qualification or registration as an apprentice. In-school instruction is delivered at the Ontario Sheet Metal Workers Training Centre in Oakville, a joint union and contractor training centre, and the apprenticeship leads to a Certificate of Qualification and the interprovincial Red Seal.

Beyond the ticket, members upgrade through SMART's International Training Institute and through courses run at the local.

Health and safety training for Ontario construction runs through the Infrastructure Health and Safety Association, the designated sector association. Workplace injury and illness coverage is administered by the Workplace Safety and Insurance Board.

SMART maintains its own occupational health arm, SMOHIT, covering the hazards specific to this trade. National reference material comes from the Canadian Centre for Occupational Health and Safety.

Members and their families are covered by medical, dental and vision care, short- and long-term disability, life insurance and prescription drug coverage, alongside a defined pension plan. Members review and manage their coverage through the Union Benefits member portal.
