In 2002, the Doors Open concept became a reality when the very first Ottawa event welcomed nearly 80 building participants and 35,000 visitors. Since then, the event continues to expand and evolve with the everchanging times, and this year is no different. Buildings will have the option to participate virtually, in-person, or a hybrid of the two. As a visitor, you can plan your ‘visits’ accordingly and follow the most current public health policies in place.

Whether you choose a virtual or live experience, you will discover the secrets and stories that lie within some of Ottawa’s most interesting buildings by way of still photography, in-depth descriptions, 3D and/or virtual tours, YouTube videos, in-person guided and self-guided tours, and more, so stay tuned!

Heritage Ottawa has been a strong supporter of Doors Open since its inception in 2002. An event designed to celebrate the city's built heritage by opening up buildings for public viewing was a perfect fit for Heritage Ottawa. Many of our members and directors were active participants in bringing the event to the city. Today, members of our board of directors continue to contribute as active participants on the Doors Open Ottawa Advisory Council.

Join us in exploring Ottawa's history, culture and stunning architecture. 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.
