Federal, provincial or municipal. That's a discussion that has to happen.
This is called strategic retreat. You carefully select those communities that should either be moved or elevated. You can elevate these homes as well, either by putting them on stilts or on berms, but they must be moved out of harm's way. You can design this program even as they've done in the Netherlands where they've created sacrificial areas. They've essentially said, “Okay, this whole area, we're just going to move. We're then going to divert water into it, and that's going to reduce flooding downstream and protect communities downstream,” so you can do this intelligently.
