Proudly Building Our Communities.

Better. Stronger. United.

Welcome to LiUNA!625. We are builders of cities and suburbs. From roads and bridges to skyscrapers and shopping malls. And the neighbourhoods we live in. Established in Windsor in 1945 and one of eleven LIUNA locals in Central and Eastern Canada, the dedication and loyalty of our 2,800 Members across southwest Ontario is unprecedented- a tradition that began in 1903 and has powered LIUNA into one of the strongest, most respected unions in Canada with Members and retirees growing to 130,000.

Inspired by a mandate that defines a progressive, proactive, positive organization, LIUNA advocates and negotiates in the best interest of our Members and their families – to ensure job creation, fair wages, free skills training, exceptional health care benefits and pension security, and the right to work safely-always. A mandate that has enabled a strike-free history, cooperative and collaborative relations with all government partners and signatory contractors and securing LIUNA’s leading role on local world-class infrastructure projects like the Rt. Hon. Herb Grey Parkway, the new $6.4 billion Gordie Howe International Bridge, scheduled for completion in 2025, plus an additional $8- $10 billion in building and infrastructure projects that include the NextStar EV Battery Plant, Highway 3 expansion,  the new Banwell Rd /EC Row interchange and the massive hospital project all slated for completion by 2030 in our jurisdiction alone.

LIUNA is a proud pioneer in establishing an inclusive barrier-free workplace where we welcome, encourage and support all individuals regardless of age, gender or cultural heritage, whether they’re construction-skilled and ready for union membership or pursuing a career path to achieve Construction Craft Worker certification at our state-of-the-art training centre.

Our commitment to build better communities extends beyond construction skills. We take a leadership role in supporting the well-being of our community, fund critical health care initiatives, fundraise for charities through Champions For Change, volunteer for special causes, and host Member functions to celebrate the LiUNA!625 family. Experience our unique ‘lifestyle’. A lifestyle that will bring many rewards in the years ahead.

Feel the Power.
