He was elected provincially, only Ontario gets to decide.
The other main party, the Liberal party, was lead by a wet paper towel that had some fairly weak stances on some subjects that people didn't like.
There is a 3rd main party, the NDP, that had been elected about 30 years ago during a financial crisis, and because of their performance, the people around at the time have vowed to never vote for them again.
Combine that with our First-Past-The-Post voting system, which translates 40%, 25%, and 25% of the votes for each party (Conservative, Liberal, NDP) to 70%, 25%, and 5% of the power for each party (Conservative, NDP, Liberal). There is also the Green party which makes up for the remaining percentages.
I think all of the above is stupid and wish it were better.
