First of all, all the funding that comes from the federal government is own-source revenue. All of the money that's in Canada comes from our lands and resources, so we're just talking about “let us control our own money”.
Second, there's no reason why first nations couldn't be receiving a portion of all federal, provincial, and municipal taxes that happen on our traditional territories. We should be getting a royalty from all the business that's conducted on every highway, water, and land area in this territory that has only been possible through the dispossession of our lands and territories.
