Trudeau needs to go, but the replacements aren't exactly compelling no matter how you slice them. It'll be Scheer or Bernier for me. Probably Scheer because Ontario already has Conservative Gov and more get's done if the party is the same throughout. Mind you allowing that for too long isn't good either. I also think Trump will be much more friendly to a Conservative Federal Gov here.
I'd guess the Conservatives will take power. Don't think it will be a landslide but also don't think it'll be a close call. The Ontario poles for Ford didn't make it look like he was going to run away with it, yet he steamrolled Liberal Premier Wynne, who unlike her name, lost. Horwath's New Democrats did ok in that election surprisingly, but I don't see the NDP having that sort of backing in this Federal election.
