Why not both?

Meanwhile, taking into account the certainty that Stephen Harper will do absolutely everything possible to barricade himself in the Prime Minister's office, let's also respond to Murray Dobbin's question:

Reform democracy or rid the country of Stephen Harper?
...
What is our goal? Do we want to finally rid the country of this execrable politician once and for all, or do we want democratic reform for the sake of democratic reform?

Of course, getting rid of Harper needs to be at the top of the to-do list. But particularly if the Cons plan to weasel their way out of any votes of non-confidence in this Parliament (or any future one), there's simply no guaranteed way to get there from here. So in the meantime, it's certainly worth some effort to put formal measures in place to limit the damage Harper can do - as well as setting up a more democratic system for future PMs.
