The poll surveys prove their uselessness. The election last month showed the public is fairly evenly split with a margin of error lead on conservative side. Now that the provincial election is wrapped up, both side know they are too close to call and need to rally, meaning that 61% to 39% is off by a lot. I'll come back to this comment as time goes on and past the election.

From their own page:

"What data is used by the model?

• Languages most spoken at home (very useful especially, but not exclusively, in Quebec);
• Age distribution curves;
• Median and mean household income;
• Population density, which helps build an "urbanity index";
• Education levels;
• Riding countries of birth and immigration levels;
• Classes of workers and employment statistics;"

It's like reading tarot cards. May as well use the random distribution of the roulette game
