Doors Open Toronto 2025 brings back fan favourites for first time in 6 years

Doors Open Toronto officially kicks off in less than three weeks, and you'll be able to visit two fan-favourite sites for the first time since 2019. 

On Monday, the City of Toronto unveiled the exciting lineup of buildings, walking tours, and special programming for this year's citywide event, which takes place on Saturday, May 24 and Sunday, May 25. 

For two days only, you'll be able to explore over 150 of Toronto's architectural, historical, cultural, and socially significant buildings completely free of charge, including the Aga Khan Museum, Evergreen Brick Works, the Legislative Assembly of Ontario, The ZoomerPlex, and the Archives of Ontario. 

New additions this year include Ubisoft Toronto, Spin Master Headquarters, St. Lawrence Market North, the YZD Experience Centre, and the Museum of Contemporary Art Toronto, to name a few, as well as returning favourites like Old City Hall and the historic Don Jail at Hennick Bridgepoint Hospital, both of which are returning for the first time in six years. 

The historic Don Jail, which was initially used as a reform jail, was created by renowned architect William Thomas and remained open for 113 years before closing in 1977. The property was eventually purchased by Bridgepoint (now Hennick Bridgepoint Hospital) and incorporated into a new health care facility. 

Through the self-guided tour, you'll be able to explore the building and access areas that are not normally open for public visitation. 

The free, one-weekend celebration of architecture and public space will take place through this year's theme of "play." A complete list of participating buildings and sites is available on the City's website.
