338Canada Ratings of Canadian Pollsters


The tables below contain information regarding the 338Canada ratings of Canadian pollsters, which are used to weight the polls used by the 338Canada model. I do not publish these results and calculations lightly, because I know ratings such as these will ruffles some feathers in polling circles and that is certainly not my goal. However, for the sake of transparency, and to offer readers an easier understanding of how pollsters have fared in this country in recent years, I feel these figures - which I have been using for years - should be made available to the reading public. The details of the 338 Score and ratings are explained in this blog post.
