Under international law, a treaty is a legally binding agreement between states (countries). A treaty can be called a convention, protocol, pact, agreement, etc. It is the content of the agreement, not its name, that makes it a treaty. Thus, the Geneva Protocol and the Biological Weapons Convention are the two treaties, although neither treaty in its name. Under U.S. law, a treaty is a legally binding agreement between countries that requires ratification and « consultation and approval » of the Senate. All other agreements (internationally treated) are called executive agreements, but are nevertheless legally binding on the United States under international law. On July 6, 2012, the City of Edmonton, represented by Mayor Stephen Mandel, signed a partnership agreement with Confederation. This was the first such agreement between a city in Alberta and a group of First Nations governments. Edmonton is part of Treaty 6 territory and has the second largest Aboriginal population of all Canadian communities.  The Government of Canada believes that the terms of the treaty were clearly recorded in the document, but because of the oral traditions of Aboriginal peoples, they have a different understanding of the terms of the treaty.  Although there were three interpreters present at the negotiations for Contract 6, two from the Crown and one from the Aboriginal peoples, it was not possible to translate words directly between English and Le Cree.
Some words in both languages did not have a corresponding word in the opposite language. This meant that the two groups did not fully understand each other, as the concepts were changed due to the exchange of words between languages. Aboriginal peoples had to rely on their interpreter, because the document they were to sign was exclusively in English, which gave them the disadvantage, since the interpreter had to explain the words, meanings and concepts of the treaty text, because the Crees could neither speak nor read English.  Aboriginal peoples claim that they accepted Treaty 6 because they were informed that the Crown did not want to buy its land, but to borrow it.  Another understanding was that indigenous peoples could choose the amount of land they wanted to keep, but surveyors came to place reworks per person on the reserves, which was considered a violation of the treaty.  Indigenous peoples believed that the treaty would adapt to agricultural conditions due to changing conditions such as the level of money, drastic changes in health services and the effectiveness of agricultural instruments that were invented or modified. However, the terms of the contract remained the same, leading indigenous peoples to believe that the terms of the contract should be reassessed to better meet the current needs of indigenous peoples.  Contract 6 is the sixth of the numbered contracts signed between 1871 and 1877 by the Canadian Crown and various First Nations. It is one of 11 numbered contracts signed between the Canadian Crown and First Nations.
In practical terms, Treaty 6 is an agreement between the Crown and the Plains and Woods Cree, Assiniboine and other governments of Fort Carlton and Fort Pitt. The key figures representing the Crown were Alexander Morris, Deputy Governor of the Northwest Territories; James McKay, Manitoba Minister of Agriculture; and W.J. Christie, the head of the Hudson`s Bay Company. Chief Mistawasis and Chief Ahtahkakoop represented the Carlton Cree.  In addition to treaties, there are other, less formal international agreements.
