It's an election, yes. But there will be a referendum on how leaders are elected in the future. Currently, the province is divided up into sections, and a single candidate is elected among several competing parties. That candidate represents that region in Parliament. The party with the most elected candidates forms a government. But this type of election doesn't take into account "by how much" did each candidate win in each region. It is possible for a government to win every region, an absolute majority, with only 51 percent of the popular vote.

The new system being proposed is called "Proportional Representation". It is identical to the previous system, with one candidate representing each region. However, additional representatives will be voted in to represent the proportion of the popular vote each party won. This way, a person who voted for the losing candidate will still be represented. The party of that losing candidate will still fill the correct proportion of the parliamentary seats.

Some have said that this will almost certainly lead to a government that will have to endlessly compromise on its policies in order to pass legislation, and that leadership will be rendered ineffective. IMO, this is a good thing, because when we vote for a party we may not agree with every policy they have. But if they win they implement all of their policies as if it were a "mandate" to do so. Sometimes they create policies just because it is the opposite of what a competing party's policy is. With the new system, they will not necessarily be able to do everything they want. If there is popular opposition to one or more of their policies they will not have sufficient votes to implement it. So, what some might term an "ineffective" government, might just be a government that can no longer do stupid things that nobody wants, just because one of their "selling points" got them elected.

These are two reasons that make "Proportional Representation" superior to the current electoral system in Ontario.
