Tom Davies Square, Town hall in Sudbury, Ontario

Tom Davies Square is Greater Sudbury's city hall, a complex of four buildings on a site bounded by Brady and Paris Streets. The triangular main building has its right angle at that corner and a glass-walled hypotenuse facing a central outdoor plaza; a diamond-shaped building to the west now houses the Greater Sudbury Police Service, a taller tower at 199 Larch holds provincial offices, and a rectangular building with a colonnade breezeway houses Bell Canada.

Built in the late 1970s as Civic Square (Place-Civique), the complex replaced an overcrowded city hall whose council met in the Mackenzie library auditorium. Local firm Townend, Stefura, Baleshta and Nicholls designed it, with Arthur Townend and John Stefura as lead architects. It was renamed in 1997 for retiring regional chairman Tom Davies.

The complex was renamed in 1997 for Tom Davies, retiring chairman of the Regional Municipality of Sudbury, not a mayor. The central plaza, redesigned in 2019, is used by city staff and residents as a pedestrian route between Brady and Paris streets and as a gathering space for civic events.

The complex sits at the corner of Brady and Paris Streets, with the glass-walled hypotenuse of the main triangular building facing the central outdoor plaza. The plaza was redesigned and completed in 2019, so the open space at the centre is newer than the surrounding buildings. The 199 Larch tower, added later at the northeast corner, holds provincial government offices.

The 2023 plan, approved in November, would move most city operations into the underused tower at 199 Larch and convert the Brady Street council building into a cultural facility housing the main public library branch and the Art Gallery of Sudbury. The federal government contributed $25 million in September 2024.
