Carney is an obvious good ideological match to lead the CPC, but I don't see that happening. More realistically, Freeland also comes to mind. Honestly, I think the CPC and LPC should just get it over with already and merge. CPC tries to cut harder right every once in a while and it never goes anywhere. They should merge so we can have a better defined left (eg NDP) center (arguably Green) and right (merged LPC/CPC, plus fringe stuff like PCP).
