No.
To me, Vincent Lemieux's term “moderate proportional representation” is excellent. If you want to develop a system proportionate with the size of Canada, it is sufficient to obtain one-third of 1% of the vote to be elected. It is also possible to implement a proportional system based on the size of the provinces. In Ontario, it is sufficient to garner 0.8% of the vote to be elected. In Quebec, it takes a little over 1% of the vote and about 10% in New Brunswick. Proportionality depends on the size of the constituencies.
Vincent Lemieux's argument is that, by creating small enough constituencies, we avoid the proliferation of political parties. This is a fundamental political issue.
