From Carp to Cumberland, over 73,000 visitors explored some of the city's most interesting places during the event's 15th consecutive year in operation.

Doors Open Ottawa continues to be the second-largest Doors Open architectural event in North America.  Since its inception in 2002, over 920,000 visitors have discovered some of the city’s most prestigious buildings including Earnscliffe: Official Residence of the British High Commissioner, the Supreme Court of Canada, the Embassy of the United States, and the Sir John A. Macdonald Building....just to name a few.

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.
