I read about the recent U.S. Supreme Court decision about the ability of the government to take private property under Eminent Domain. Interesting theory.
We don't have that here in Canada. No need. We're so passive, all the government would need to do is say "please".
Government: "We need your land!"
Person: "No! Are you friggin' nuts! Get the hell out of here!"
Government: "Alright, you leave us no choice. We need your land, PLEASE."
Person: "Well geez, if you're saying please, then I dunno. I guess. Here are the keys."
