Doors Open

Doors Open, held annually on the first weekend in June, is a once-a-year opportunity to tour some of Ottawa’s most fascinating and unusual places.

Come and explore 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.

Last year more than 120 of Ottawa's most extraordinary buildings opened their doors to the public.

Doors Open Ottawa celebrated its 15th anniversary in 2016, and continues to be one of the largest Doors Open architectural events in North America. For a complete list of last year's participating sites, click the PDF link below for the Doors Open 2016 program.

The next Doors Open Ottawa weekend takes place on June 3 and 4, 2017. Check back in May 2017 for full details.
