Heritage Mississauga is a not-for-profit charity and the only independent city-wide organization devoted to heritage matters. Established in 1960 to develop and manage a Museum focused on the Bradley family of 1840, Heritage Mississauga changed its mandate in 1994 to focus its work on researching, recording and celebrating Mississauga’s heritage.
Heritage Mississauga advocates for the preservation of our city’s heritage legacy through dedicated programming focused on oral history, record keeping, outreach and celebrations. Our shared heritage is an important element in fostering and maintaining Mississauga’s sense of community, pride and history. Together with the support of community groups, corporations and individuals, Heritage Mississauga continues to accept the challenge of promoting awareness of the community’s most precious non-renewable resource.
Heritage Mississauga (Mississauga Heritage Foundation) began in 1960 when a citizens’ group was organized by the then-Township of Toronto to move a heritage home that once belonged to a United Empire Loyalist family (the Bradley’s), to a permanent location, and open a community museum (Bradley House Museum Complex, managed by the Museums of Mississauga today).
In 1994, when the City took over the management of the Museum, Heritage Mississauga had the opportunity to redefine its mandate to focus on researching, recording and celebrating the heritage of the entire city.
In 2004, the organization moved from its offices at the Civic Centre to one of the oldest City owned buildings in Mississauga, the historic Robinson-Adamson House “The Grange” c1828, (1921 Dundas Street West, Mississauga). At “The Grange” Heritage Mississauga provides the community with a comprehensive Heritage Resource Centre.
Heritage Mississauga strives to create a sustainable heritage resource that will continue to contribute to the cultural vibrancy of the local community and which is available to all. Recognized as experts in the field of research, writing and program delivery, the organization works in partnership with the community to deliver effective and interesting programs and services.
