The electionprediction.org site predicts three Liberal wins in the cities plus the Conservatives in the Saskatchewan seat. It should be understood these are predictions by the person who runs the site. His record is good but far from perfect.
Meanwhile, the Green Party has released the results of polls in three of the four ridings, predicting a Conservative win in Saskatchewan plus Liberal wins in Willowdale and Quadra. While the Greens trail, the results are not surprisingly flattering to them, ranging from 12 to 19% (higher if the undecided are excluded). TC thinks they look much too high. Curiously however, no poll in Toronto Centre.
