What We Do

The Historical Society of Ottawa (HSO) is Ottawa’s oldest historical organization. It was founded in 1898 by a group of prominent Ottawa women interested in the preservation of Canada’s rich historical heritage at a time when there were few Canadian museums and little government funding for such activities. Initially known as the Women’s Canadian Historical Society of Ottawa, the Society changed its name in 1955 when men were allowed to participate as full members.

The Society’s objective is to preserve and increase public knowledge of the history of Ottawa, including its people and places, through publications, meetings, tours, awards, sponsored research and the maintenance of a Reference Library in the City of Ottawa Archives; participation in local heritage events; and to support and encourage heritage conservation.

At monthly meetings, held from September to June, guest speakers inform and engage members in a wide range of topics related to the history of Ottawa and the Ottawa Valley. The monthly meetings are open to the general public as well as to members at no cost. Society members also receive a quarterly newsletter, and copies of HSO’s “Pamphlet Series” that examine local historical issues. The Society also organizes one-day bus tours for its members and guests to historic sites in Eastern Ontario and Western Quebec.

The Society is the official patron of the Ottawa Regional Heritage Fair for area youth (Grades 5-9) which is held annually. At the Fair, the Society presents the Sir Richard William Scott Historical Society Award in recognition of research excellence in a subject relevant to Ottawa’s history. The Society also presents annually the Algonquin College Award to a student in the College’s Applied Museum Studies Program, and the Colonel John By Award to a university undergraduate or graduate student who writes the best history paper on a topic of relevance to Ottawa or the Ottawa Valley. 

The Society welcomes everybody with a love of history and an interest in Ottawa’s heritage, irrespective of race, religion, sex, age, country of origin, or any other attribute.
