That is an extremely ironic statement. Canada exists on land that they hold title to (according to our laws). It's only now that we've begun to recognize the reality of that, and what that means.
Sure, but that doesn't mean they get to do whatever they want. There's laws and courts that should be followed until such time that it's changed in the law. I'm perfectly fine with changing the law to meet their needs and sovereign claims but we can't have chaos until that happens.
They have territory in Canada, ok well what does the law say about building on that land? If they want the law changed, ok let's work to change the law. Until then, we go by what the law and the courts say as of right now. If you want to challenge a court decision, then challenge it. Lots of pro bono lawyers out there i'm sure willing to help them and make a name for themselves.
It's fine and good to listen to protestors, but we shouldn't be negotiating with them, it's ridiculous. The law is the law, enforce the law. The truth is the gov doesn't want to do it because it's bad PR, gotta be PC.
