2018 is the first election in which Ontario municipalities are permitted to use ranked ballot voting (thanks to the Municipal Elections Modernization Act, 2016).
London, Ontario will be using ranked ballot voting in the 2018 election. They did not have a referendum, their council decided the benefits of ranked ballots were worth implementing right away.
Kingston and Cambridge, Ontario decided to put this decision in the hands of the people and are holding referendums to see if they should move to this voting system for the 2022 elections.
The people of Kingston, along with Cambridge, have the historic opportunity to be the first city in Canada to vote to implement a better electoral system.
