That referendum asked which of five voting systems residents would prefer to use in electing members to the Legislative Assembly of Prince Edward Island.

[2][3][4] The referendum, after four instant run-off rounds, indicated mixed member proportional representation was the preferred choice with over 52% support on the final ballot.

[5] Premier Wade MacLauchlan said after the vote that he is doubtful the result of the referendum "can be said to constitute a clear expression of the will of Prince Edward Islanders" due to the low voter turnout relative to provincial general elections.

[7][8] A motion by Green Party leader Peter Bevan-Baker to implement mixed-member proportional representation in line with the referendum results was defeated on November 22, 2016, by a vote of 6–20.

said that the result showed there was "significant support" for MMP, and that the group was calling on the government to convene a citizens assembly to study electoral reform.

[22] Responding to the results, Progressive Conservative leader Dennis King said Islanders have an interest in furthering the conversation on how they govern themselves and elect members of the legislature.

[24] Peter Bevan-Baker, leader of the Green Party, called the results "agonizingly close" and said it is inevitable that proportional representation is coming but that PEI is not going to be the province leading the charge.
