Visit the Archives of Ontario on Monday, November 7 between 1:00 and 4:00 p.m. during Treaties Recognition Week for a rare opportunity to see the original written document of Treaty No. 9 — the James Bay Treaty from 1905-1906 that covers roughly two-thirds of Ontario.

You can also learn about the context and different interpretations of the treaty, its impact on Indigenous communities, and the role that archival records and other forms of memory have come to play in its story by visiting our James Bay Treaty (Treaty No. 9) online exhibit.
