The CBC Election Pollcast, hosted by CBC poll analyst and founder Éric Grenier, explores the world of political polls, their influence on the media and the trends they are showing.

Joining Éric on this week's podcast is Phil Authier, political reporter for the Montreal Gazette. He has reported on the NDP-commissioned poll for Justin Trudeau's riding of Papineau, and the resulting controversy.

How should the media handle these polls paid for by political parties? Did the media do the right thing in this case? And how do the election chances of the three Montreal-based leaders (Justin Trudeau, Thomas Mulcair and Gilles Duceppe) look?
