A coalition is not the same as a minority government, there has only ever been 2 canadian coalitions. It's pretty unlikely that will happen.
I think a minority supported by BQ will be good for the environment, significant tightening on immigration, probably liberal agenda otherwise. the BQ is much more closely aligned with Libs than CPC, as I think Blanchet made clear in the english debate. A LIB+NDP+Green isn't totally out of the question right now, probably also good for the environment.
So about 69% of the voters elected 169 liberals? Nice.
