Strangely I've noticed the exact opposite in remote northern Ontario; the feds fund better data access than the the nearby (non FN) communities because the feds give money to Bell and Rogers to improve local access who turn around and pocket the money, think up excuses and deliver a watered-down service 10 years later.
The more FNs are allowed to participate in their own futures, even if it is via grants or guaranteed loans to make equity stakes in a project, the better off they will be, and the less of a financial burden. Some are taking stakes in resource projects, power transmission projects, etc., in turn for a share in employment and the profits. It's never going to be consistent. Some want to be partners in resource development; others adamantly not.
One thing I would like to see is the Nations and feds work out some manner of title transfer for reserve lands. No resident has property equity and there is virtually no 'pride of ownership. I don't know how they would do that. Right now, the feds aren't great landlords, but some councils can be be pretty draconian as well. Housing and infrastructure in remote, fly-in FNTs is always going to be a challenge no matter who is responsible for doing it.
