The Archives of Ontario is collaborating with partners to share an original copy of Treaty 9 in Toronto and Timmins during Treaties Recognition Week (November 3-9, 2024). By sharing the Treaty, we hope to increase access to this important living document among Indigenous communities and create opportunities for students to gain a deeper understanding of treaties, treaty obligations and the oral version of the Treaty 9.

Watch this space or contact us at reference@ontario.ca for more information on how and when to view Treaty 9.

The Archives of Ontario is pleased to launch its new online exhibit “Slavery and Abolition in Upper Canada.” The exhibit is a refresh and a reframing of the Archives’ 2007 exhibit “Enslaved Africans in Upper Canada.” We hope that through this exhibit, we can encourage a greater understanding of the history of slavery and the lasting impact it has had on Black communities in the province.
