And this is why the LPC will never pass electoral reform (except for ranked ballot, because they're more likely to be everyone's second choice) because under full PR they'd never, ever, get another majority government despite having tepid support among the voting population. For the record, the CPC wouldn't even support ranked ballots as they're almost never the second choice of anyone (because their policies--when they can be bothered to articulate them--are unpopular, believe it or not)
For the record, no Canadian political party has had >50% of the popular vote in half a century, and even before then it was exceedingly rare. FPtP allows the LPC or CPC to sneak a majority in, anyways.
