The Oshawa Historical Society was founded in 1957 and is an affiliate of the Ontario Historical Society. The purpose of the Oshawa Historical Society is to bring together those individuals interested in the diverse historical aspects of Oshawa and to research, record, retain, preserve, and present historical information pertaining to the Oshawa area.

The Oshawa Historical Society also manages the Oshawa Museum. For over 65 years, the Oshawa Museum has celebrated our city’s history with engaging events, inspiring exhibits, and an extensive collection of archival materials. Nestled on the shores of Lake Ontario in beautiful Lakeview Park, the Oshawa Museum tells the story of Oshawa from the earliest Indigenous settlements to the present day.

The Oshawa Museum is situated on the traditional territory and treaty lands of the Mississaugas of Scugog Island First Nation. Our work on these lands acknowledges the signatory communities of the Williams Treaties, as well as the Mississauga Nation and other members of the broader Indigenous community, for their resilience, and their longstanding contributions to the area now known as Durham Region.
