Event information

Digital Doors Open Ottawa

While the City of Ottawa has cancelled the 2020 Doors Open Ottawa event (originally scheduled for June 6-7), visitors can still enjoy Digital Doors Open Ottawa - where they can explore some traditional Doors Open Ottawa sites without having to leave home. The following sites offer tours, videos and activities that will engage people of all ages.


Info from the City of Ottawa

After careful consideration and following the recent update provided by Mayor Jim Watson, Doors Open Ottawa, originally scheduled for June 6 and 7, will not be taking place this year. While this has been a difficult decision, it is crucial that we follow recommendations made by public health officials to help slow the spread of COVID-19.

We recognize and appreciate the time and effort that has gone into planning Doors Open Ottawa 2020. Doors Open Ottawa has celebrated Ottawa’s built heritage for 18 years and we look forward to once again opening doors to the community on June 5 and 6, 2021.

Thank you for your support, understanding and participation in our continued efforts to plank the curve in the interest of preserving the health and safety of Ottawa residents.

Diefenbunker: Canada's Cold War Museum

The Diefenbunker: Canada’s Cold War Museum is a four-storey Cold War bunker built to protect the government from a nuclear attack on Ottawa. Once top-secret, this underground facility is now open year-round. During Digital Doors Open, you can explore this site through a series of virtual tours, download some colouring pages from their collections, keep busy with various jigsaw puzzles, or play the online game, Project Rustic (Flash required). And learn more in the video below from Historica Canada about the Cold War and the important role that this site played.
