I'm not sure I'm following you. The NDP coalition got dental and perceptions added to public health. Is that (plus other smaller stuff) not a big enough win for a minority party to get in a coalition government?
I just don't get Canadian politics. The party that wants to deregulate everything so the 1% can capture even more wealth at everyone else's expense (and that's punching down on trans kids and wants to roll back women's rights) is beating the party that wants to help the bottom four quintiles of Canadians.
