This is a list of National Historic Sites (French: Lieux historiques nationaux du Canada) in Canada's most populous city, Toronto, Ontario. There are 36 National Historic Sites in Toronto. The first National Historic Site to be designated in the city was Fort York in 1923.
National Historic Sites located elsewhere in Ontario are listed at List of National Historic Sites of Canada in Ontario, with additional breakout lists for some cities. These sites are part of a federal designation program that includes National Historic Events and National Historic Persons. Each is typically marked by a federal plaque. Certain sites are part of the national park system, administered by Parks Canada, though there are none in Toronto. Bead Hill National Historic Site, in eastern Scarborough, is slated to join the park system once Rouge National Urban Park is expanded to include that area. It would become Toronto's only National Historic Site in the national park system.
This list uses names designated by the Historic Sites and Monuments Board of Canada, which may differ from other names for these sites.
