Explore Toronto's Buildings
Saturday, May 27 to Sunday, May 28, 2017

Since its inception in 2000, Doors Open Toronto has attracted more than two million visits to nearly 700 unique locations. It is Canada's largest Doors Open event and one of the three largest in the world. 

The 18th annual edition is scheduled for May 27 to 28, 2017, and offers an opportunity to see inside more than 150 architecturally, historically, culturally and socially significant buildings across the city.

The 2017 theme is Fifteen Decades of Canadian Architecture and features highlights from each decade since the 1860s, as well as a pre-Confederation cluster. By looking at our architectural, design and urban planning past, we can more easily look ahead to the next 15 decades!

Doors Open is produced by the City of Toronto in partnership with the broader community.
