context_page_description: The Toronto City Hall, or New City Hall, is the seat of the municipal government of Toronto, Ontario, Canada, and one of the city's most distinctive landmarks. Designed by Finnish architect Viljo Revell and landscape architect Richard Strong, and engineered by Hannskarl Bandel, the building opened in 1965. It was built to replace Old City Hall, which had housed city offices since 1899. The current city hall, located at Nathan Phillips Square, is the city's fourth and was built to replace its predecessor which the city outgrew shortly after its completion.

  Hester How Daycare Centre opens 1990 and named after a Toronto teacher Hester How who helped turn around delinquent boys in the second half of the 19th Century.
  Minor upgrades by Toronto architect Bruce Kuwabara to connect the two towers and upgrade council chambers in 1997-1998
  East Tower Observation deck closed - the 27th floor deck has been opened during Doors Open and one councilor has asked for a seasonal opening Access to the floor is via two sets of stairs as elevators end at 25th Floor.
  Gift shop closed
  City Hall library reduced in size
  The ice rink is still used for skating during winter, but people cannot use the pool/fountain area to wade in during summer
  A green roof was added late 2009 and opened to over 10,000 visitors on Doors Open Toronto weekend in May 2010.  The site now contains largest publicly accessible green roof in the city.
  City Hall was designated as a property of historical and architectural significance under the Ontario Heritage Act in 1991. In 2005, the building celebrated its 40th birthday.
