Stratford City Hall National Historic Site of Canada is prominently located on a triangular-shaped civic ‘square’ that forms the centre of the business district in Stratford, Ontario. Built at the end of the 19th century, it is a monumental town hall constructed of red brick with a prominent clock tower. Its Picturesque design incorporates an eclectic blend of late-Victorian features. The formal recognition consists of the building on its legal property.

Stratford City Hall was designated a national historic site of Canada in 1976 because it is significant as a late 19th-century Picturesque civic building. Stratford City Hall reflects the development of town halls during the late-19th century, as the administrative functions of municipal government increased and cities sought to express their civic pride and ambition in impressive, large-scale buildings. Its Picturesque design, incorporating details from a variety of styles, reflects the architectural eclecticism of the late 1890s. Designed by Toronto architect George W. King, with the assistance of local architect J.W. Siddall, the building was intended to exploit its irregular site, presenting interesting façades from all angles. Its monumental scale, prominent tower and use of red brick distinguish it as a civic building.
