Discover Your Hidden History with Heritage Toronto

Doors Open Toronto invites the public to explore the city’s most-loved buildings and sites for free each year during the last weekend of May. The event provides rare access to spaces not usually open to the public and free access to locations that would otherwise charge an admission fee. Since its inception in 2000, Doors Open Toronto has attracted more than two million visits to nearly 700 unique sites and is the largest event of its kind in Canada.
