Mackenzie House, House museum with Georgian architecture in downtown Toronto, Canada.

Mackenzie House is a three-storey Georgian townhouse at 82 Bond Street in downtown Toronto, built of yellowish-tan brick. Its symmetrical facade has a black paneled door with a transom window, two ground-floor windows with black louvered shutters, and three white-framed sash windows on each of the upper floors. Inside, period furnishings reflect an 1860s upper-middle-class home.

The three-storey brick townhouse was purchased in 1858 by Mackenzie's friends and supporters, not built then; sources give a construction date of 1836. Mackenzie, Toronto's first mayor and leader of the 1837 Upper Canada Rebellion, lived there until his death in 1861. After a sheriff's seizure in 1864, John Taylor let the family stay rent-free, and in 1868 Isabel Mackenzie repurchased it with funds from the Ontario Legislature.

The museum bears the name of William Lyon Mackenzie, who founded the Colonial Advocate newspaper and led the 1837 Upper Canada Rebellion. A working 19th-century printing press lets visitors see the tools of his trade. Exhibits also cover Black Canadians and Mary Ann Shadd, and in 2025 the museum partnered with Dundee Culture, a site promoting Mackenzie's Scottish birthplace.

Entry is through the front door on Bond Street, where visitors are guided through the different rooms across all three floors. Comfortable shoes are helpful since there are many stairs and narrow passages to navigate inside.

The side panels of the Memorial Arch that once stood at the foot of the Honeymoon Bridge in Niagara Falls are displayed in the small courtyard next to the house. The arch was built in the 1930s, dismantled in the 1960s, and the panels were installed here in 1974.
