jeffery simpson has a book called "the friendly dictatorship" that sums up the absolute power in the pmo.
the last thing i want is an elected judiciary. i find it refreshing that the courts are a guardian of our rights and do not dismiss liberties based on political whims. the supreme court upholds our rights under the charter and deems some government legislation unconstitutional, which makes that legislation null and void. However the courts do take into account the objectives of the government when making a decision. The courts have deferred to parliment more and more in recent years, and i think this is a good mix between upholding civil liberties and upholding the notion of parlimentary supremacy.
i would agree though, that senate reform is needed. the senate right now is useless and the only way to make it useful is to bring in the triple e senate. elected, effective, equal.
As for the house of commons, the opposition parties seem to be slowly putting things together. The responsibility of the opposition parties is to keep pressure on the governing party, this pressure is the reason why the governing party is not actually dictatorial. The governing party wants to get re elected and if the opposition parties put enough pressure on the government regarding an issue and there is public outcry, the government usually softens its stance to appease the opposition and lessen the anger of the public. So the opposition parties do play an important role in shaping policy for this country.
Having said that, chretien is more dictatorial than most PM's have been. the reason is, there is no effective opposition so he can pass pretty much any legislation he wants, with out fear of seriously hurting his chances of being re-elected. This type of arrogance is starting to become more of an issue and could lead to chretiens eventual downfall. since there is no opposition ready to govern, the only way to get rid of chretien it seems, is to have paul martin win the liberal leadership, which is better than nothing i guess.
