Doors Open Toronto returns this month, and the 2025 edition of the event is set to include some exciting new spots to explore. Doors Open, the city's annual festival that allows rare glimpses into buildings, properties and areas not typically open to the public, is coming back this month. This year, the Don Jail and Old City Hall are also making a comeback after a six-year hiatus, but those aren't the only fresh additions making things extra exciting for Doors Open 2025. The long-awaited new home of St. Lawrence Market's Saturday Farmers' Market has finally opened for business, but you can get an even deeper look during Doors Open, when the market building will be open both during the Farmer's Market on Saturday and during its downtime on Sunday. This year at Doors Open, the curtain is getting peeled back on the place that made games like Assassin's Creed and Far Cry possible.
