not accurate - it would hurt it because now no one has a majority so they would cater to BQ in certain situations to prop up whatever party needs a few more seats for power. Right now sure they have representation but no real power. They cannot win the election at all. With PR, the Bloc gains power as now people have to cater to them (or another party) to get a majority of votes if anyone wants anything passed. So yes they are overly represented but with no real power. Put in PR, and they are more proportionally represented and yet have way more power.
