Interesting, I'm somewhat shocked that the fed has no ability to direct and deploy the Mounties, but I wont argue with a Canadian. That said, I think the democratic solution is to act through ones representatives, impeach the premier, ect.

I also dont see why the emergency act, if declared, couldn't be used to enforce existing laws and remove the truckers.

I think my core point is that there are conventional and broadly accepted methods to take when people are breaking the law. People breaking the law does not provide a blank check to stop them by any means desired.
