A non-binding referendum on electoral reform[1][2] was held in the Canadian province of Prince Edward Island between 27 October – 7 November 2016.

This was the second electoral reform referendum to be held in Prince Edward Island, following a vote to maintain the status quo in 2005.

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

[11] In-person voting was open in polling stations across the province on Friday, 4 November 2016, 4:00 p.m. - 9:00 p.m., and Saturday, 5 November 2016, 10:00 a.m. - 8:00 p.m.[12] Premier Wade MacLauchlan said after the vote that he was doubtful the result of the referendum "can be said to constitute a clear expression of the will of Prince Edward Islanders" due to the unusually low turnout.

[13] MacLauchlan did commit to discussing the results when the provincial legislature resumed on 15 November 2016; noting the need to examine the urban and rural breakdown of votes, among other issues.

[15][16] A motion by Green Party leader Peter Bevan-Baker to implement mixed-member proportional representation in line with the referendum results was defeated on 22 November 2016 by a vote of 6–20.

[17] A subsequent electoral reform referendum was held on 23 April 2019, simultaneously with the 66th Prince Edward Island general election.
