About this source
What it is
This is a hand-drawn survey map, known as the Ridout Survey, completed in 1821 by Thomas Ridout, Surveyor General of Upper Canada. It shows the lands granted to the Six Nations along the Grand River, running from Lake Erie to Lake Ontario, with numbered and named lots and an inset map.
Why it matters
These lands were granted under the 1784 Haldimand Proclamation to the Six Nations, including the Mohawk people Joseph Brant led to this territory after the American Revolution. The map documents the formal boundaries of a settlement that became central to Haudenosaunee life in Canada, and shows how colonial authorities recorded Indigenous land grants.
Look closer

- Whose interests does a map like this serve, and whose voices are missing from it?
- How might the Six Nations themselves have understood this land differently from how the surveyor recorded it?
