Designed by Moriyama & Teshima Architects and completed in 2009, the new City Hall is located adjacent to the historic Old City Hall, which itself is now serving as a Provincial Offences Courthouse. Prior to the construction of the new City Hall, municipal departments had been spread across five different downtown locations. The Guelph Memorial Gardens arena was demolished to make way for the new civic building.
The City Hall was built to meet the LEED Silver standard set out by the Canada Green Building Council. As a result, operating costs are 30 to 40 percent lower than that of a similarly-sized typical office building.
