The Markham Civic Centre is the city hall of the city of Markham, Ontario. The brick and glass Civic Centre was designed by architect Arthur Erickson with Richard Stevens Architects Limited and was opened on May 25, 1990. The entrances, except for the great hall entrance, are named after communities in Markham (Unionville, Milliken, Thornhill). The building is adjacent to an 11.5-hectare park with a large pond reflecting the south façade.
