In the 2003 Ontario provincial election, the four ridings elected three Liberal MPPs and a Progressive Conservative.

Under the existing voting system, 50.68% of the voters got the representative they voted for.

The other 49.32% of the votes were wasted.


In our model, the seats would have been allocated as follows:

Under this model, 90.89% of the voters would have helped to elect a local representative.

Another 8.97% of the voters would know that their vote had helped to elect provincial list members, so they would also have representation.

Only 0.13% of the votes cast would not have helped to elect an MPP, and therefore would have been wasted.
