338Canada Projection Update: December 16th 2018

We add to the projection the Forum poll published last Sunday and the Nanos update (here is the full list).

You can access those projections by region:

This 338Canada Projection includes the following political parties: the Liberal Party of Canada, the Conservative Party of Canada, the New Democratic Party, the Green Party of Canada, the Bloc québécois, and the People's Party of Canada.

Here are the regional breakdowns per party:

While it is legitimate to wonder whether last week's Nanos numbers fluctuated this drastically because of noisy data (especially the 28 point swing in Ontario between Libs and Tories), Forum's numbers were inline with what Forum has been measuring all throughout 2018.

Here are all the federal polls of 2018, with Forum's polls indicated by a black arrow:

So there is a clear trend in Forum's numbers: they tend to favour conservatives more than any other firm on the field in Canada.

That being said, I do not discard Forum's numbers entirely. However, the 338Canada model automatically gives a poll lesser weight in its calculation if it is seen as an outlier (said poll would regain its due weight if it is later confirmed by other polls).

And so here is the popular vote projection for December 16th 2018:

The most significant swing this week is the gap between the Liberals and Conservatives closing by an average of 1.6 point. The Liberals are still heavy favourites, but as you can see on the chart below, the confidence intervals are now overlapping:

Here is the seat projection. The threshold of majority at the House of Commons is 170 seats.
