Update (Oct 17): Based on this week’s polls, new information has been added for the following three ridings at the end of the article: Coquitlam — Port Coquitlam (BC), and Essex (ON).

Short version:

We found 16 special ridings that will change the outcome of the election. In these ridings: the conservative candidate is ahead, one of the progressive candidates is a close second, while the other is a distant third but still has enough support to impact the result. Brampton Centre and Prince George are two examples:

Two of ridings that will change the election

In both ridings, the 3rd-placed candidate has little chance of winning but could guarantee the victory of his or her progressive counterpart.

There are 14 other ridings where the same thing could easily happen. If the Liberal and NDP parties cooperate in all 16 ridings, they will each take 8 seats from the conservatives, stopping the Conservative party from forming the government!
