It's not an unlikely scenario, the past two elections haven't resulted in a majority government (which I personally think is extremely healthy). If this poll was the seat proportion on election day we'd likely see something a bit rarer where the plurality party would be excluded from government but it'd be pretty consistent with the past two elections... Trudeau's popularity slumps while CPC palatability to other Canadians continues to decline. Lil' PP certainly isn't going to attract any centrist voters.
