Doors Open Ottawa 2017

Visit one or more of the 151 buildings that will be open to visitors next weekend for the annual Doors Open Ottawa. That's probably a record number. View archives, churches, colleges and universities, embassies, museums, public utilities, recreational facilities, schools, and more. A few, such as the US Embassy, require advance registration.
