LIUNA members build office towers, apartment buildings, schools, sports facilities, shopping malls, parking garages, factories and many other types of buildings, including houses.

Heavy Construction and Highway Construction
LIUNA members build roadways, bridges, dams, power plants and other major construction projects.

Manufacturing & Commerce
Although LIUNA began in 1903 as a construction union, our members now work in many types of factories and processing plants. We also work in stores, offices, hotels, restaurants and offices.

Public Sector
Government-funded services is one of the fastest-growing areas of LIUNA membership, from hospitals and nursing homes to school boards, municipal streets and parks departments, waste management and recreation, to name just a few.

We’re an International Union
As our full name says, LIUNA is an International Union, with members in both Canada and the United States. Across the continent, we are over half a million strong. Although we run our own affairs in Canada, we are proud to be an important part of one of North America’s oldest and most powerful unions. Our long tradition of cross-border cooperation continues to benefit members in both countries.
