New LiUNA Local 183 headquarters to be built in Vaughan


Diamond Schmitt Architects has announced that it has been selected to design a multi-use building in the City of Vaughan for the Labourers’ International Union of North America (LiUNA) Local 183.

The building, located in a new urban precinct in Vaughan, will consist of a six-storey tower connected to a three-storey wing that sits dramatically on an assembly hall, which is buried in the landscape.

The key feature of the 295,000 sq. ft. headquarters will be a highly-transparent glazing system. In addition to the assembly hall, the building will also have offices, medical clinic facilities, a pharmacy, financial services, training classrooms, and recreational facilities for union members.

The soft landscaping will extend up and over top of the assembly hall with access to portions of the building’s rooftops. This unique amenity activates the outdoor space to socialize in a protected microclimate and supports the project’s LEED Silver sustainability goals for storm water retention and heat island reduction, Diamond Schmitt Architects said in a statement.

The project is expected to break ground in the fall of 2018, with a targeted opening date of 2020, according to a report in

LIUNA Local 183 is the largest union local in North America.
