The Six Nations of the Grand River Band is suing the governments of Canada and Ontario in a court case that started in 1995. The Band says that under the 1784 Haldimand Proclamation, which it considers a treaty, the British Crown set aside about 950,000 acres of lands along the Grand River in Ontario which the Six Nations of the Grand River and their descendants were to enjoy forever.

The Band says that after 1784, the British Crown, and later the governments of Canada and Ontario, failed to set aside these lands, improperly sold most of them to settlers, and mismanaged the proceeds of sales from them. The Band is asking the court to make findings to this effect, and seeking compensation from the governments of Canada and Ontario for these historical wrongs.
