Each May, Doors Open Toronto — presented by Great Gulf — invites you to explore the city’s most-loved buildings and sites, free of charge. The event provides rare access to buildings that are not usually open to the public and free access to sites that would usually charge an admission fee. Since its inception in 2000, it has attracted more than two million visits to nearly 700 unique locations. It remains the largest event of its kind in Canada.

Lists of featured sites are available on the website: https://www.toronto.ca/explore-enjoy/festivals-events/doors-open-toronto/
