The issue is that the top parties feel secure in their oligarchy. It doesn't really matter which one is in power as they're always relevant and can squabble as they like.

They don't feel threatened during elections anymore because it's not about leading the country in a better direction according to their party principals, but it's about what each person can personally gain by doing favours.

I'm worried that the only way to actually make positive change is to put one of the minor parties in charge. Maybe seeing the Green party or the Communist Party of Canada in charge for a few years'll be what it takes to make the mainstream parties actually fix their crap. Of course, the level of a miracle for something like that to happen is so remote that it's hard to see any hope in the government without some sort of major upheaval to happen.
