Doors Open Ottawa

The City of Ottawa is proud to present Doors Open Ottawa, a free annual architectural event that celebrates our community’s built heritage…and you’re invited! It is the second-largest Doors Open event in Canada, and one of the largest in the world!

On June 2 and 3, discover the secrets and stories of over 140 unique buildings that have shaped the Ottawa landscape, such as the Supreme Court of Canada, Hydro Ottawa’s new Hydroelectric facility at Chaudière Falls, the Global Centre for Pluralism, and the Bank of Canada.

Whether you’re a resident or visitor to the nation’s capital, we also invite you to take advantage of the free Doors Open Ottawa Shuttle Bus, operating within walking distance of over 50 participating buildings. If you prefer to walk, no problem! With so many choices, visitors can explore numerous buildings per day on foot within the downtown core.

Join us during the first full weekend in June to pay homage to Ottawa’s history, culture, and stunning architecture during Doors Open Ottawa 2018! It’s free, it’s fun, and it’s the perfect way to discover how Canada’s Capital has become the beautiful city it is today. And don’t forget… Share your #DoorsOpenOttawa experience on Facebook, Twitter, and Instagram.
