in-person event information

Saturday, June 4 and Sunday, June 5, 2022 from 10 a.m. to 4 p.m.

Welcome to the 20th anniversary of Doors Open Ottawa! Visitors are invited to explore nearly 60 of Ottawa’s most beautiful and interesting building sites live and in-person during the first full weekend in June. 

During each visit, we kindly remind guests to adhere to any specific entry requirements that may be posted by our building partners. After a two-year hiatus from hosting a live event, please be patient and enjoy this exciting new phase as we re-open the doors to Ottawa’s built heritage!


Info from the City of Ottawa

The City of Ottawa is thrilled to participate in this year’s hybrid Doors Open Ontario event. Doors Open Ottawa has been showcasing the unique built heritage of the nation’s capital since 2002, and we look forward to opening both live and virtual doors to the Ottawa community – and beyond.

In celebration of our 20th anniversary, the Ottawa Regional Society of Architects and Doors Open Ottawa have joined forces to create a scavenger hunt. To win one of 50 gift cards from local Ottawa area businesses, submit a digital Doors Open Ottawa scavenger hunt entry form between June 3 and 5, 2022. Visit for full contest details, and to access this year’s full building list – which will be available online from May 30.

We hope you enjoy the opportunity to visit nearly 100 buildings that are historically, functionally, culturally and architecturally significant in nature – from Cumberland to Carp and everywhere in between!

The main house here is considered to be one of the oldest homes in Ottawa. The Billings family lived here for five generations. Once a large agricultural property, parts of the estate were given to different family members or sold off. Today, what remains is a museum, several outbuildings and a cemetery for more than 140 community and family members.
