Campbell House is an 1822 heritage house and museum in downtown Toronto, Ontario, Canada. It was built for Upper Canada Chief Justice Sir William Campbell and his wife Hannah. The home was designed for entertaining and comfort, and constructed at a time when the Campbells were socially and economically established and their children had grown to adulthood. The house is one of the few remaining examples of Georgian architecture left in Toronto and is constructed in a style in vogue during the late Georgian era known as Palladian architecture. History The house was originally located on a plot of land southeast of its current location, at the intersection of what is now Adelaide Street (then 64 Duke Street) and Frederick Street. More specifically, it stood at the head of Frederick Street as a view terminus, on the site presently occupied by George Brown College's Chef School or Centre for Hospitality at 300 Adelaide Street East. Upon Sir William Campbell's death in 1834, his estate conveyed the house to his wife, Lady Campbell, for her use. After Lady Campbell's death in 1844, her estate auctioned the property and the contents of the house with the proceeds distributed amongst their heirs. For most of the 19th century the structure remained a private residence. It was home to various prominent citizens (Hon. James Gordon, Terence O’Neil, John Strathy and John Fensom) until 1890, by which point the neighbourhood had changed into a commercial and industrial zone. The building eventually came to be used by several businesses after the turn of the 20th century as office space and a factory, including Hobbs Glass Company; Capewell Horse Nail Company and Masco Elevator Company. In 1972, the last owners of the property, the Coutts-Hallmark Greeting Cards Company, wanted to demolish the house to expand its parking lot. Prior to demolition the company offered the house to anyone who could remove it from the property. A professional association of trial lawyers known as the Advocates Society, launched a campaign to save the building. They eventually secured the site at the northwest corner of University Avenue and Queen Street West, south of the Canada Life Building (formerly site of three buildings at the corner including United Clothing Store). With assistance from maintenance trucks of the Toronto Transit Commission, the home was moved northwest from Adelaide Street to the north side of Queen Street West, between University Avenue and
