In celebration of Canada's 150th anniversary, pay homage to Ottawa’s history, culture, and stunning architecture during Doors Open Ottawa 2017!

This year, over 150 historically, culturally and functionally significant buildings will open their doors for free for the public’s viewing pleasure. From Carp to Cumberland, over 80,000 visitors are expected to explore some of the city's most interesting places during the event's 16th consecutive year in operation.

Whether you're a resident or visitor to the nation's capital, take advantage of the Doors Open Ottawa Shuttle Bus, operating within walking distance of over 50 participating buildings. Or take the opportunity to enjoy the summer sun and cycle your way around the city on a Doors Open Ottawa bicycle tour. No bike, no problem! Visitors can visit numerous buildings per day by making their way around the downtown core on foot.

Volunteers are key to making Doors Open Ottawa great!

During this 150th anniversary year, enlist family and friends to join you in giving the gift of time. Show off Ottawa's treasured sites and buildings while helping thousands of visitors celebrate this historical and cultural event.
