The City Hall of Toronto, Ontario, Canada is the home of the city's municipal government and one of its most distinctive landmarks. Designed by Finnish architect Viljo Revell (with Heikki Castrén, Bengt Lundsten, Seppo Valjus) and landscape architect Richard Strong, and engineered by Hannskarl Bandel, the building opened in 1965. It was built to replace Old City Hall, which was built in 1899.The current City Hall, located at Nathan Phillips Square, is actually Toronto's fourth city hall and was built in order to replace the former city hall due to a shortage of space. The area of Toronto City Hall and the civic square was formerly the location of Toronto's Old Chinatown, which was expropriated and bulldozed during the mid-1950s in preparation for a new civic building.

The North York Civic Centre is a building that once served as the city hall for the former City of North York, Ontario, Canada.
Designed by Adamson Associates Architects, the building is located on Yonge Street north of Sheppard Avenue, and features Mel Lastman Square along the Yonge Street frontage. The construction of the building was intended to act as a catalyst for the development of the "North York City Centre", a downtown area for the formerly suburban North York. The building received The Governor General's Medal for Architecture in 1982.
With municipal amalgamation, North York is now part of the City of Toronto, and the building no longer serves as a city hall. Today, the building is home to the North York Community Council and a number of local municipal departments and services. Opposite the Civic Centre is the North York Central branch of the Toronto Public Library.
