I think strong cultural investment is a good way to start and beneficial to canadians as a whole. I went on vacation to Haida Gwaii recently and really appreciated the Haida Heritage Center[1] but those places are few and far between - the funding for it actually originated in a standoff with the government[2] that was then invested and nurtured to accrue the value it has today. They host seminars and classes around culture and history while employing a number of reservation residents - I think it'd be wonderful if the federal government put a more serious investment into cultural preservation as a way to spur economic health.
There are other actions being called for by the tribes themselves but I hope that cultural investment ends up being part of the end solution.
