The financing part?

Already happening. Loads of loans are being held up in the Vancouver area because no one is sure who owns what:

Right. Which makes it pretty likely that if the federal government is entering into agreement, one of the things the agreement would do is resolve that issue. Because that's what the federal government would probably regard as a necessary prerequisite to giving the tribes anything.

In another post I linked how the tribes are asserting their ownership of the land...over people who had no idea the tribes were the real owners.

Yeah, but that's a completely different legal issue. Those properties were lands that the tribe actually owned through "conventional" forms of ownership, and the people who had the mobile home thought - mistakenly - that they had some right of ownership in the mobile home tracts. They didn't. That's not uncommon, BTW; we run into it from time to time here in Florida. People who "buy" mobile homes often mistakenly think that they're buying a house the way that someone buying a single-family detached home is buying a house. But they usually are not. They're buying the structure itself which is not a fixture to the land, and (at best) are taking over a lease on the mobile home lot which is under the mobile home.

Given the ramifications of the ruling and any deals the Canadian government makes on behalf of the citizens who thought they owned property there should have been much more transparency.

Maybe. From what you've posted in the past, it seemed like the federal government regarded this as a whackadoodle judge who was certain to get overturned on appeal. And the tribe itself had elsewhere said that they were not interested in obtaining any ownership interests in private property in their lawsuit, but rather "to defend its traditional territory and fishing rights":

...which makes it pretty likely (though not certain!) that the agreement isn't to give away Vancouver, but rather the federal government agreeing to tribal requests for sovereignty on its own land and concessions on those fishing rights in exchange for formal acknowledgment by the tribe that they're not claiming ownership of private property.

Again, we won't know until we see. But that seems vastly more likely than the implausible scenario that the federal government has entered into an agreement that would worsen any title uncertainty on the better part of Metro Vancouver, much less "give Vancouver away." If they reached an agreement, it wouldn't do that - if that was what the tribe demanded, they'd just continue the appeal.
