De nation à nation: une ressource sur les traités en Ontario is the French language edition of the Union of Ontario Indians' treaty guide, Nation to Nation: A Resource on Treaties in Ontario by Maurice Switzer.  This 68-page French language book from the Union of Ontario Indians is designed to inform readers and students about First Nations treaties in Ontario. Edited by Maurice Switzer the book has a definition section and background about treaties in general, treaties between First Nations, the Royal Proclamation of 1763, Indian treaties in Canada, and a timeline showing Indian treaties in Ontario. Specific treaties such as Treaty of Niagara 1764, Chippewa Treaties, Manitoulin Treaties, Robinson Superior Treaty, Robinson Huron Treaty, and Williams Treaties are described. A brief overview of the significance of the War of 1812 is explored. News articles about treaties and the contemporary reality of these nation to nation relationships add to the understanding of their importance today. The final essay is Patrick Madahbee’s call to action for instituting a process to mend the relationship between Canada and Ontario First Nations.  This important collection clarifies the often confusing picture about treaties by focusing on treaties covering Ontario from their origin to the present day. Background data was provided by the Canadian Encyclopedia, and historians Maurice Switzer, Alan Corbiere, and David Shanahan. An excellent resource for secondary level students as well as college, university, and the general reader.
