Walnut Hall was a row of four Georgian-style terraced homes in Toronto, Ontario, Canada. Constructed in 1856, it was recognized by both the Government of Canada and the City of Toronto as being of historic significance, but portions of it collapsed and it had to be demolished in 2007 due to neglect. At the time of its demolition, it was Toronto's last remaining complete row of 19th century Georgian townhomes.
