Your effort is commendable, but in fairness only the 15 seats above could really have flipped under FPTP. It's unreasonable to expect parties to pull candidates in line for 3rd place, or voters to cast ballots strategically on a large scale.
What your list does show is that if Trudeau had successfully carried out his promised electoral reform, he would without a doubt be sitting on a majority of ~180 today.
