Ministry of Public and Business Service Delivery
Established in 1903, the Archives of Ontario is Canada’s largest provincial archives.
Our objective is also to capture the records of enduring provincial significance
illustrating the history and development of Ontario.
We act as the guardian of Ontario’s documentary memory under the Archives and Recordkeeping Act (2006). As the official repository for the archival records of the Province of Ontario, we strive to acquire records from the private sector which document the many facets of Ontario's diverse society, and provide a reflection of the interaction between the government and its citizens.
The records in our collection are from individuals and organizations that tell the stories of Ontario’s people, document events and trends with wide-ranging social or political impact, and reflect the province’s cultural diversity.
