I know that the government likes to do a pan-aboriginal approach, which is a one-size-fits-all approach. That's just not always possible, depending on which treaty area you're in. Sometimes you have areas that don't even have treaties, like British Columbia. They don't have any, except for the modern-day ones like the Nisga'a have. However, they're not covered off by any. I think most first nations would reject that anyway. The Anishinabek Nation is different from the Haudenosaunee Confederacy, and so forth. They even have different treaties.
For instance, in Ontario, we have the beaver hunting grounds, which are covered off by the 1701 Nanfan treaty; and the 1701 Dish With One Spoon treaty, which also led up to 1764 at Niagara Falls, with the proclamation.
There are a lot of overlapping things that we have to look at, and a pan-aboriginal approach doesn't work a lot of the time.
