Big difference between the US system and the parliamentary system in Canada...there are separation of powers and often divided government here in the US. In Parliament, if the liberals win, they control everything. In the US, you have to control the Presidency and both houses of Congress. It does not happen often.
Plus, if in the US, Alberta and Saskatchewan would have other states as allies. They would not be on their own fending off the federal government.
Interestingly, Canada today probably functions a lot like the U.S. would operate if we respected our own Tenth Amendment.
