Operated by the City of Toronto, this gas-lit Victorian structure was once home to the city's first mayor, William Lyon Mackenzie. In the 1930s, local citizens saved the house from demolition, and it was restored and opened as a public attraction in 1950. Today, a gallery addition features changing exhibits, and the costumed staff presents demonstrations of 19th century life. Special programs for children are offered during summer months, and the site is available for private functions.
