MECHANICAL CONTRACTORS ASSOCIATION ONTARIO
The unified voice of the mechanical contracting industry in Ontario.
WHO WE ARE
The Mechanical Contractors Association of Ontario (MCAO) is a provincial, not-for-profit organization committed to advancing, promoting, and supporting Ontario’s mechanical contracting industry. Representing nearly 300 dedicated professionals and member companies, MCAO brings stability, value, and leadership to the industry across the province.
WHAT WE OFFER
MCAO is proud to provide evolving educational opportunities, business resources, and member representation. Through partnerships with government agencies and industry associations, we offer access to a wide range of training programs—many of which are subsidized to help our members grow their skills and expertise.
OUR ROLE
As an accredited bargaining agency with the Ontario Labour Relations Board, MCAO represents all unionized mechanical contractors in Ontario. Our volunteer board of directors—composed of leaders from member companies—advocates on behalf of the industry at every level of government.
PROVINCE-WIDE PRESENCE
Ontario is divided into fourteen regional zones, each served by its own local Mechanical Contractors Association. While these zones operate independently, they work in close alignment with MCAO to deliver valuable benefits, resources, and support tailored to their local members.
