The Ontario Construction Secretariat (OCS) was formed in 1993 to represent the collective interests of the unionized construction industry in Ontario’s industrial, commercial, and institutional (ICI) construction sector.
As a joint labour-management organization, OCS is dedicated to enhancing Ontario’s unionized ICI construction industry by developing relationships, facilitating dialogue, and providing value-added research.
Research is the foundation of the OCS that underpins each of the OCS strategic objectives: Improved Labour Relations; Positive Perceptions of Unionized Construction; and Supportive Public Policy.
Our stakeholders include the twenty-five unionized construction trades and their contractor partners. OCS is also pleased to have provincial government appointees to its Board of Directors.
Representing over 130,000 union members and 5,000 union contractors, the OCS is a trusted leader in delivering non-partisan and impartial research and advice to our industry and government stakeholders.
