Election simulator

Our predictions use polling numbers and other data to calculate each party’s chance of winning a particular seat (read our methodology for more on how it works). We run simulated elections in each riding 1,000 times. The average of all of these simulations gives us our national forecast.

Try it for yourself below: When you hit “new simulation,” winning parties are assigned for each seat based on our projection of how likely they are to come out on top.

Poll tracker

Our simulations are based on publicly available polls, including the ones below. You can examine the raw numbers and filter them based on methodology or which firms conducted the polls.

All polls conducted since the January 1, 2015.
Polls are considered to be more accurate when they sample the opinions of more people. This filter excludes some polls with smaller sample sizes, which reduces the margin of error associated with the results. Specifically, polls conducted with fewer than 1,500 respondents are not included.
This filter includes only polls with very large sample sizes, which reduces the associated error further.
