The Atlantic provinces and Quebec are probably the biggest reason we won’t see PR actually take affect. They currently have massive over representation constitutionally guaranteed and I highly doubt they are gonna give that up without a massive fight.

The closest we will ever get is a different way to count votes within the current riding system, which is still not PR at the end of the day.

(And aside from the fact that PR doesn’t solve the issue of more populace regions fucking over less populace ones without regard)
